From Heartfelt Letters to Happy Homes – Innovating Dog Adoption Through AI

This is Bailey – a rescue my wife found and adopted from Alabama, and behind her is a picture and memory corner of our late dog, Neo. Neo introduced us to a new world of pet parenting. He passed away unexpectedly at the age of 2 due to an undiagnosed congenital disease. Since then, we have connected with fantastic pet welfare and rescue organizations. This personal journey also led to ‘Pawsome Innovations’ to assist pet rescues, shelters, pet care, vets, and pet parents through innovative solutions. Everything via “Pawsome Innovations” is dedicated to pets, pet shelters, rescues, and organizations facilitating their adoptions.

This journey since the last few years and realization of possibilities through AI/ML models led to one such innovation: matching dogs for adoption at rescues and shelters with pet parents looking to adopt. The solution continually evolves, and the matching model’s accuracy improves with each iteration as we learn more. It’s still in it’s nascent stage, but continues to get better.

The origin of this solution is in the letter my two sons wrote to my wife and me before we had Neo – our first dog. When they were little, they convinced us to get a dog through a heartfelt letter, promising to care for the dog and also help with all chores. This letter was like a contract, though the most significant clause was that we, as parents, were the only parties genuinely responsible. This letter was the best lobbying effort and made us realize what we were missing and what a dog could bring to our lives.

Here is the step-by-step explanation of the solution –

Language agnostic letter as input:

Inspired by that heartfelt letter, expressing their desire for a dog, I realized that such letters could be a powerful way to connect people with dogs in rescues and shelters. Finding the perfect dog goes beyond checking boxes on websites or searching online like we do for products. It’s not just about attributes like size or weight; it’s about adding a new member to the family.

There’s a more profound connection formed through subtle, unspoken love, emotions, expressions, and the unique bonds dogs bring into our lives. This is where a letter of expression plays a crucial role. It’s not just about stating our desires but also considering what’s best for the dog in a long-term home. Such letters can help potential pet parents easily navigate the adoption process, providing predictability and better preparation for welcoming a new furry family member.

Individuals write letters, in their preferred language, detailing their lifestyle, home environment, expectations of their would-be furry kid, and what they are willing to give and sacrifice for that unique furry child. These letters become the basis for finding the best match among dogs in rescues.

Utilizing Large Language Models (LLMs):

This solution uses the ‘gpt-4o’ LLM model via an API call to parse the letter. This highly advanced model can understand and extract nuanced information from the text. The LLM identifies critical attributes from the letter, such as a dog’s lifestyle preferences, specific needs, and desired traits. These attributes are crucial for the matching process.

Vector Analysis and Retrieval Augmented Generation (RAG):

The extracted attributes are transformed into vectors. These vectors represent the attributes in a numerical format that can be compared with other data. Retrieval Augmented Generation (RAG) uses these vectors to retrieve relevant information from a rescue and shelter database and identify the top dogs that best match the attributes extracted from the letter. Here is the function in the code to match preferences with pet data and return top five matches:

def match_preferences_with_pets(traits, pet_data):
combined_fields = pet_data.apply(lambda row: ' '.join([...]), axis=1)

pet_descriptions = combined_fields.tolist()
traits_embedding = model.encode([traits])
pet_embeddings = model.encode(pet_descriptions)
print(f"This is what model picked: {pet_embeddings}")


cosine_similarities = cosine_similarity(traits_embedding, pet_embeddings).flatten()
related_pet_indices = cosine_similarities.argsort()[-5:][::-1]
return pet_data.iloc[related_pet_indices]

This is what this function is doing-

  • Combines relevant fields from pet data into a single description.
  • Converts the traits and pet descriptions into numerical embeddings.
  • Calculates similarity scores and finds the top 5 matches.

Tailored Adoption Plan:

As accuracy increases, a new feature to this solution will be added – after identifying potential matches, this solution would also suggest a tailored adoption plan for each dog. This plan would include recommendations for a preferred diet, behavioral tips, what to expect on the first day, weeks, and months after adoption, and strategies to ease the transition and acclimatization post-adoption. The plan will be based on available information about the dog’s traits, known behaviors, also genetics, and other breed-specific information.

Machine Learning Model Development:

The matching model is continually evolving. Each iteration involves refining the model with more data and improved algorithms to enhance accuracy.

This solution uses various data sources, including Rescuegroup.org and Dog Aging Project 2022 Curated Data, for educational and research purposes. This data helps train the model to understand different dog attributes and match dogs with potential adopters.

Building the Pet Matching and Adoption ML Model:

Key attributes extracted from the letters and dog profiles are used to create features for the ML model. These features include lifestyle compatibility, activity level, breed-specific needs, and health considerations.

Python for Implementation:

Python is extensively used to implement the solution. Libraries such as pandas, numpy, and sklearn are used for data preprocessing, model training, and evaluation.

Using Python, we preprocess the data, train the machine learning models, and evaluate their predictions. The process involves:

  • Cleaning the data.
  • Transforming it into suitable formats.
  • Feeding it into the model for training.

Our furry friends are here to make our lives “PawSome”. This solution combines advanced ML techniques, data normalization, analysis, and a compassionate approach to improve the lives of dogs and their new families. This journey has been deeply personal, motivating, and rewarding, driven by our love for dogs and our commitment to making a difference in the pet community.

Acknowledgement & Thanks : Rescuegroup.org and Dog Aging Project 2022 Curated Data have graciously shared data about the dogs for educational and research purposes.


And here is a sample letter and output from the code (entire code and the model will be available via a dedicated site to anyone interested in further building on it for the welfare of our furry friends)

Dear Future Furry Companion,

We hope this letter finds you well, wherever you are. My name is James, and my wife Linda and I are looking for a special dog to join our family here on our peaceful farm in Maine. We are both retired veterans who served our country with pride and dedication. Our farm is a haven of tranquility, filled with the sounds of nature and the laughter of our two 10-year-old grandkids who visit us often.

I have had a deep bond with dogs throughout my life. During my time in Vietnam, I had a loyal companion named Max who was more than just a dog to me. Max was my protector, my confidant, and my friend during some of the most challenging times. His unwavering loyalty and love provided me with the strength to endure those days. After the war, Max continued to be my steadfast companion until his last days, and his memory lives on in my heart.

Linda and I have always had a soft spot for dogs, and our farm has seen its fair share of furry friends over the years. We have always believed in giving a loving home to dogs in need, and we prefer to adopt from rescues because every dog deserves a chance at a happy life.

Our farm is a wonderful place for a dog who loves to run, explore, and be part of a family. We have a variety of farm animals, and it’s important to us that our new companion is comfortable and friendly with them. We also have other dogs who are very much a part of our family, and we hope that you will get along well with them too.

Our grandkids are full of energy and love spending time with our animals. They are kind and gentle, and they have grown up learning how to care for and respect animals. We are looking for a dog who will be their friend, someone they can grow up with and create beautiful memories together.

We promise to provide you with a loving home, plenty of adventures, and all the care you need. Our hearts and doors are open, and we are ready to welcome you with open arms. You will be more than just a pet to us; you will be a cherished member of our family.

We can’t wait to meet you, to share our lives with you, and to create new memories together. Until then, stay safe and know that there is a warm and loving home waiting for you here in Maine.

With love and anticipation,

James and Linda
