   <abstract>
    Every year, a higher number of dogs are abandoned or euthanised due to temperament issues and a lack of understanding by owners regarding dog behaviour and training. This research focuses on the potential to make predictions of adult dog temperament based on early puppy behaviours by using a machine learning model. Specifically, the research used guard dog breeds, such as American Bully, American Pit Bull Terrier, and German Shepherd. The study collected dog data and general data from dog owners and used the Random Forest approach to build a predictive model. Users are allowed to input puppy data and receive adult dog temperament predictions in model, which is integrated into a web application. The aims of this web application are to enhance responsible dog ownership and reduce abandonment by offering insights and training recommendations based on predicted outcomes. The model achieved a prediction accuracy of 86% on testing, and it is continually improving, though further refinement is recommended to improve its reliability and applicability across a broader range of breeds. The study contributes to canine welfare by providing a practical solution for predicting temperament outcomes, ultimately helping to reduce shelter populations and euthanasia rates.

     <xref ref-type="bibr" rid="scirp.137264-"></xref>1.1. Background</title>
    <p>Currently, a significant number of canines around the world are getting put down or ending up in shelters even by their owners due to temperament issues. Even the world has an availability of different dog breeds who are most likely to be adopted or petted, in an increasing manner, the number of dogs all around the world is going through tough times related to putting down and sheltering <xref ref-type="bibr" rid="scirp.137264-1">
      [1]
     </xref>. When purchasing a dog as a pet, attractiveness and likability are the factors that most people focus on <xref ref-type="bibr" rid="scirp.137264-2">
      [2]
     </xref>. As of today, most dog lovers buy dogs without knowing the requirements and housing conditions. A dog’s requirements should always match with their owner’s requirements and their housing conditions. Also, it was noted that most dog owners are not training their dogs at early stages and not making time for their dogs <xref ref-type="bibr" rid="scirp.137264-3">
      [3]
     </xref>. And dog owners must have the knowledge to raise dogs properly regarding the well-being of dogs, which can help to reduce behaviour problems in dogs <xref ref-type="bibr" rid="scirp.137264-4">
      [4]
     </xref>. The primary matter is canines getting ended up in shelters and getting put down due to behavioural problems arising for the reason of the lack of knowledge in owner’s viewpoint regarding dog’s requirements, housing conditions and owner’s requirements <xref ref-type="bibr" rid="scirp.137264-5">
      [5]
     </xref>. The result can be fatal as some dogs can get aggressive for strangers, such as new people or animals and even can get aggressive to their owner and family. Then, most of the time, those aggressive dogs will get put down or end up in shelters by those owners. Now, in the animal welfare sector, it’s becoming a highly important and considerable matter. After ending up in shelters, dogs can have the risk of homelessness <xref ref-type="bibr" rid="scirp.137264-6">
      [6]
     </xref>. While investigating the connection between puppy behaviors and adult dog temperament, the research provides knowledge to people and prevents dogs from getting put down and ending up in shelters by providing an innovative solution through predicting adult dog temperament based on puppy behaviors.</p>
    <p>
     <xref ref-type="bibr" rid="scirp.137264-"></xref>There were previous findings available related to temperament of dogs. Previous research was performed for German Shepherd dogs bred for the purpose of Swedish military working dog program and used C-BARQ (Canine Behavioral Assessment and Research Questionnaire) to investigate dog behaviours and experiences. Sudden dummy appearances, structures of frightening floors, human social interactions and noisy sounds were used in T-test (temperament test) to find out the eligibility to grow into military working dogs. The research results showed that behaviours and experiences of puppies in the first 12 months of their life majorly impact for their later temperament <xref ref-type="bibr" rid="scirp.137264-7">
      [7]
     </xref>. It was found that it’s hard to apply standardized dog behavioural tests and also recommended to use standardized dog behavioural tests such as the DMA (Dog Mentality Assessment) or Serpell and Hsu developed method for evaluating guide dog temperament <xref ref-type="bibr" rid="scirp.137264-8">
      [8]
     </xref>. It was found that previous researchers used different kinds of statistical models. C-BARQ and IFT (In-For-Training), a standardized temperament evaluation used to predict the success of assistance dog training, which resulted in high accuracy rate in a previous research paper <xref ref-type="bibr" rid="scirp.137264-9">
      [9]
     </xref>. Also, behaviour tests were conducted for the purpose of puppy prediction for the suitability as detection dogs and recommending further validation of behaviour tests for different breeds <xref ref-type="bibr" rid="scirp.137264-10">
      [10]
     </xref>. Also, previously had a behaviour recognition based on multimodal data, which were collected through a wearable device and a camera to apply in health monitoring and treatment of dogs <xref ref-type="bibr" rid="scirp.137264-11">
      [11]
     </xref>. An earlier study reviewed about past research studies relating to different studies of dog temperament and also mentions that most of the studies were focused on Labrador Retrievers and German Shepherd dog breeds <xref ref-type="bibr" rid="scirp.137264-12">
      [12]
     </xref>. Earlier research was focused on predictive validity of behavioural tests only regarding military working dogs to evaluate relationships among those behaviours <xref ref-type="bibr" rid="scirp.137264-13">
      [13]
     </xref>. In a past study, they were unable to find proof connecting paw preference to temperament, except that the lateralized dogs outscored ambilateral dogs on a test of stranger-directed aggression <xref ref-type="bibr" rid="scirp.137264-14">
      [14]
     </xref>. Also, found that specific breed temperament may be triggered by certain mutations in genes, whereas other characteristics may reflect wide range of inherited behaviours of “ancient” lineage or selection by humans for the purpose of particular functional skills <xref ref-type="bibr" rid="scirp.137264-15">
      [15]
     </xref>. Also, Bennett, Litster, Weng, Walker and Leuscher assessed the effectiveness of evaluation tools, SAFER (Safety Assessment for Evaluating Rehoming) and mAAP (modified version of Assess-A-Pet), in predicting aggression of dogs using 67 dogs and comparing their behaviour histories with the C-BARQ, and discovered that mAAP had better sensitivity and specificity for recognizing aggressive dogs than SAFER. Also, <xref ref-type="bibr" rid="scirp.137264-16">
      [16]
     </xref> discovered that both these tools were imperfect for predicting aggression. Another earlier research suggested that temperament tests in the previous research were developed without scientific systematic approach. They identified five main key measures (practicality, reliability, purpose, validity, standardization) of a temperament test to influence a new approach <xref ref-type="bibr" rid="scirp.137264-17">
      [17]
     </xref>. Most of the previous research was done without systematic approaches.</p>
    <p>As stated by Shelter Animals Count 2023, which is the national database that collects data from most of the animal shelters in world, the percentage of dogs that were relinquished to shelters by owners was 24% in 2019, 2021, 2022 and 2023 <xref ref-type="bibr" rid="scirp.137264-18">
      [18]
     </xref>. The percentage of dogs non-live outcomes in shelters was 36% in 2019 and 2021, 44% in 2022 and 47% in 2023 <xref ref-type="bibr" rid="scirp.137264-18">
      [18]

    <p>Related to the temperament and behaviours of dogs, many of the previous researchers have researched dog breeds such as Golden Retrievers <xref ref-type="bibr" rid="scirp.137264-9">

      [15]
     </xref>. In the world, there are many more dog breeds available. 200 dog breeds are currently registered in the AKC (American Kennel Club) <xref ref-type="bibr" rid="scirp.137264-19">
      [19]
     </xref> and over 300 breeds are currently recognized in the UKC (United Kennel Club) <xref ref-type="bibr" rid="scirp.137264-20">
      [20]
     </xref>. With that gap in mind, other dog breeds like American Bully, American Pit Bull Terrier, etc. related research can be addressed. Also, most researchers have previously focused on companion dogs <xref ref-type="bibr" rid="scirp.137264-3">

      [26]
     </xref>. This research focuses on enhancing the well-being of dogs by predicting their adult temperament from their puppy behaviours and taking steps to give proper training to them, etc. to reduce attacks in public society.</p>
    <p>This research study focuses on predicting adult dog temperament based on puppy behaviours using Random Forest ML approach and also, found that there is no previous research done on predicting adult dog temperament based on puppy behaviours and experiences using a ML prediction model with Random Forest approach. The study provides users with a solution and the knowledge to develop responsible ownership of dogs and positive human-dog relationships, helping canine welfare by reducing the dog count getting put down and ending up in shelters. This improves the well-being of canines as well as dog owners, also shelters and dog rescue groups through an inventive approach.</p>

    <sec id="s1">
     <title>2. Methods</title>
     <p>The main target of the research is to gather dog data and general data from dog owners. With that strategy in mind, data gathered by calling through phone, physically visiting and by Google Surveys, and then used for the analysis process. After gathering of data phase, organized and stored data in an excel sheet as in Comma-Separated Values (CSVs) <xref ref-type="bibr" rid="scirp.137264-27">
       [27]
      </xref> format which was more suited when feeding to the machine learning model in the model training process. Dataset contained same dogs’ adult dog behaviors and puppy behaviors. Dog behaviour attributes such as energy level, shyness/outgoingness, reaction to owner and the family, reaction to new people, behavior around other animals, responsiveness to common commands, specific behavioural issues, and general data attributes such as having other animals at home, having children in home, perform trainings for the dog, each day hours spending with the dog, etc. contributed to predict the adult dog temperament in the solution of the study. Most of these attributes are highly valued key variables to affect dog temperament <xref ref-type="bibr" rid="scirp.137264-4">
       [4]
      </xref> <xref ref-type="bibr" rid="scirp.137264-28">

      </xref>-<xref ref-type="bibr" rid="scirp.137264-33">
       [33]
      </xref>. Then, the data preprocessing part done through feature engineering by focusing on categorizing behaviour data and handling missing values to attain the best results. Overall, all the findings provided the training data for the ML predictive model. In the Discussion and Findings section, some of the graphs and charts are displaying processed data related to dogs and their owners. Then, the dataset absorbed into the ML model which uses the Random Forest ML approach that can handle complicated relationships with a medium to large dataset <xref ref-type="bibr" rid="scirp.137264-34">
       [34]
      </xref> <xref ref-type="bibr" rid="scirp.137264-35">
       [35]
      </xref>. While Decision Trees approach is useful but may not capture the complexity of the relationships in the data as effectively in this research because it is good for small, simple and well-structured datasets <xref ref-type="bibr" rid="scirp.137264-35">
       [35]
      </xref>. While focusing on Neural Networks approach, it typically requires much larger datasets. Also, the training of Neural Networks approach is very time-consuming and can be computationally intensive <xref ref-type="bibr" rid="scirp.137264-36">
       [36]
      </xref>. The difficulty of interpreting trained models is one of the primary issues with neural networks approach <xref ref-type="bibr" rid="scirp.137264-36">
       [36]
      </xref>. When comparing with other ML approaches, Random forest approach is fast to train <xref ref-type="bibr" rid="scirp.137264-37">
       [37]
      </xref>. Random Forest approach can outperform Neural Networks approach over specific cases and also can have advantages when comparing with Neural Networks approach <xref ref-type="bibr" rid="scirp.137264-36">
       [36]
      </xref>. The Random Forest approach was chosen as the better option for this research project. The model was then trained. After the model training process, it was evaluated. Then the predicting model integrated with a web application. Users can be able to input puppy data into the integrated web application to get adult dog temperament predictions of those puppies. Also additionally, based on the predicted adult dog temperament results, the software provides valuable insights such as recommendations, insights and training plan generators to users. By making better decisions such as perform trainings for the dog, etc. can improve the well-being of their dogs and their relationships <xref ref-type="bibr" rid="scirp.137264-38">
       [38]

     <title>3.1. Findings</title>
     <p>The analysis had a broad area of dog data and general data. In this section, some of the charts and graphs are showcasing processed data related to owners and their dogs.</p>
     <p>Data were collected on the dog breeds of American Bully, American Pit Bull Terrier, German Shepherd, Rottweiler, Labrador Retriever and Boxer. The study’s aim is on the guard dog category and also because of the low number of responses to several dog breeds, had to drop Labrador Retriever, Rottweiler and Boxer dog breed data. The research then targeted American Bully, American Pit Bull Terrier and German Shepherd guard dog breeds. Forty nine percent of German Shepherd, 28.1 percent of American Pit Bull Terrier and 22.9 percent of American Bully data were analysed in the total of 96 data in the dataset (<xref ref-type="fig" rid="fig2">
       Figure 2
      </xref>). Collected dog data count displayed these guard dog breeds are crucial for the temperament prediction by displaying different patterns regarding the temperament throughout the breeds, had to consider that different breeds have different behaviours. Within the breeds that identified, 60.4 percent of male animals and 39.6 percent of female animals were found. In the real world, both male and female dogs have different temperaments and having data on both genders provide a significant impact to the solution. Because male and female dogs are having different temperaments, the user can understand and determine which dog gender temperament traits are positive or negative at the final result.</p>

     </fig>
     <p>Dog’s energy level was one of the most essential choices because it is a key indicator to the activity level of dogs and by being aware of this trait aids to predict dog temperament <xref ref-type="bibr" rid="scirp.137264-7">
       [7]
      </xref>. Ninety-nine percent of energy levels were at high, while moderate energy levels were at one percent in the collected dataset (<xref ref-type="fig" rid="fig3">
       Figure 3
      </xref>). Dog’s shyness/outgoingness is a main factor in sociability level of dogs. Canines can have confident behaviours, fearful behaviours, etc. <xref ref-type="bibr" rid="scirp.137264-8">
       [8]
      </xref>. Regarding the research, outgoingness simply spells out that adaptation can be done easily, and shyness requires more socialization. Outgoingness was at 94.8 percent, while shyness was at 5.2 percent in the gathered dataset. By being aware of this attribute aids to predict dog temperament (<xref ref-type="fig" rid="fig4">

      </xref>). In the collected dataset, most of the dogs were friendly to their owner and their family at a percentage of 97.9. Dogs who aggressive towards the owner and family members were very lower at a percentage of 2.1 (<xref ref-type="fig" rid="fig5">
       Figure 5
      </xref>). When concentrating on the dog’s reactions to new people in the gathered dataset, majority of dogs were friendly at a percentage of 59.4, some of the dogs were reserved at 31.3 percent and lesser number of dogs were aggressive at a percentage of 9.4 (<xref ref-type="fig" rid="fig6">
       Figure 6
      </xref>). And when concentrating on the dog behaviour around other animals in the dataset, majority of dogs were friendly at a percentage of 60.4, some of the dogs were reserved at a percentage of 31.3 and lesser number of dogs were aggressive at a percentage of 8.3 (<xref ref-type="fig" rid="fig7">
       Figure 7
      </xref>). Friendly reactions indicate positivity of trust and sociability. Reserved reactions indicates neutral action between friendly and aggressiveness but still needs light training. Aggressive reactions indicate negativity and attention required for training <xref ref-type="bibr" rid="scirp.137264-3">
       [3]
      </xref>. These traits are heavily required for predicting temperament of dogs. Also, the research identified that some dogs had some specific behavioural issues such as aggressiveness that led them to attack new people and other animals sometimes, and very lower number of dogs were aggressive towards their owner and their family. If specific behavioural issues like aggression are discovered, then required to have the attention for training methods. This trait is strongly recommended for predicting temperament of adult dogs in the research solution. When concentrating on responsiveness to common commands trait, most of the dogs were responsive at a percentage of 77.1 and some of the dogs were not responsive to their owners at a percentage of 22.9 which refers to dog obedience and the trainability (<xref ref-type="fig" rid="fig8">
       Figure 8
      </xref>). This trait is also, strongly aids to predict the adult temperament of dogs. Dog’s energy level, shyness/outgoingness, reaction to owner and the family, reaction to new people, behavior around other animals, specific behavioral issues, responsiveness to common commands are key and main ingredients in the study because these traits provide a thorough overview of a dog’s early stage which is definitely affecting that dog’s adult temperament <xref ref-type="bibr" rid="scirp.137264-8">

     <p>In conclusion, the temperament prediction section is chosen as the main feature of the solution. Furthermore, we decided to add more extra features like providing recommendations, insights and training plan generators based on the predicted adult dog temperament results. Each and every dog owner who provided the data to the research was very concerned regarding behaviours of dogs as dogs mature into adult dogs. That makes the project solution is required to build and will be successful among end users. By understanding dog behaviours properly, dog owners can have positive impact on their dog’s well-being.</p>

     <p>Frontend application, backend application, machine learning model and database acted as the main units in the software architecture that the study followed. In the frontend application, interactive interfaces were designed using React library to handle client-side interactions. Integrated with the Python ML model, backend is implemented using Flask (Python) framework and Node.js to handle server-side interactions. The machine learning model is the unit that is responsible for the adult dog prediction based on early puppy behavior data and the model was trained using dog data and general data in the dataset that was collected from dog owners. The model is implemented primarily using Python programming language. Data preprocessing part is done through feature engineering by focusing on categorizing behaviour data and handling missing values. In the process, split data into training (80%) and testing (20%) sets. Trained the model using Random Forest ML approach because Random Forest approach is more suitable to handle complex relationships with a medium-large dataset, as encountered in this research. Also, performed hyperparameter tuning and evaluated the model to enhance the accuracy to fulfill the expectations of the study. After saving and loading the model, predicted the target values. After implementing the ML model, integration of the model to the backend application process happened. MongoDB Atlas cloud database is used to perform CRUD operations for software data and model parameters. After all processes were done, to validate the finalized software solution, tests were conducted and found issues were instantly addressed and fixed.</p>

    <title>6. Conclusions</title>
    <p>In the research study, the research question addressed is how to predict adult dog temperament based on puppy behaviours and experiences to reduce the count of dogs getting ending up in shelters and getting put down. The study covered and made a lot of effort to show it as a considerable work in the subjective areas. Using the Random Forest approach, the ML model was able to predict the temperament of adult dogs with 86% of good performance accuracy based on puppy behaviours and is continually improving.</p>
    <p>The study has demonstrated that it is feasible to predict adult dog temperament based on puppy behaviours and experiences. By analysing and examining factors like dog breed, dog gender, energy level, shyness/outgoingness, reaction to owner and the family, reaction to new people, behavior around other animals, specific behavioral issues, responsiveness to common commands, home type, having children in home, having other animals at home, each day hours spending with the dog, perform training for the dog, etc., most of which are highly valued key variables to affect dog temperament, develop a machine learning prediction model with Random Forest approach to predict and provide adult dog temperament to users. This can help users to understand and address potential temperament issues of dogs with better decisions in early stages, like performing training sessions for their dogs and making enough time for their dogs. This can improve their bond with dogs and can lead the path to reducing the count of dogs ending up in shelters or getting put down due to behavioural issues. Also, with the help of the tool, users who are willing to buy or adopt dogs can get the understanding and then can choose and get a suitable dog based on their requirements. Shelters and dog rescue groups can also use the tool as a solution to predict adult dog temperament and find suitable adopters by matching predicted dog temperament. This can reduce the count of dogs who are homeless or living in shelters and find them a happy home. Tracking dog behaviour data from puppy to adulthood provided greater value by allowing us to get the knowledge of how puppy behaviours change over time. The solution tool also offers users with recommendations, insights and training plans for the predicted results to make informed and better decisions regarding whether managing an existing dog or choosing a new dog. Although the research study has made a considerable amount of work towards the adult dog temperament prediction, there are some areas that still need to be addressed. Further studies could address on enhanced prediction models via much larger and more diverse datasets. Furthermore, the research should continuously prioritize on the well-being of dogs and any other innovative approaches to fulfill needs regarding the welfare of dogs.</p>
    <p>In conclusion, the research is a major step towards the understanding of dog temperament and behaviours to promote responsible dog ownerships. To enhance positive human-dog relationships and well-being of dogs, we could further continue to accelerate the field of canine behaviour using modern and innovative approaches.</p>
