We often say that we would do anything for our dog, but sometimes we feel helpless despite our best efforts. One dog dad decided to take matters into his own hands using an unlikely skill to help his dog—and the results were fascinating.
Paul Conyngham is not a doctor, nor does he have any background in biology or oncology. However, the engineer has 17 years of experience in machine learning, plus a rescue dog he would do anything for. When conventional treatment failed to help his eight-year-old rescue dog Rose, he turned to something he knows best: machine learning.
Rose is a Staffordshire-shar-pei mix that Conyngham adopted from a shelter in 2019. The dog was diagnosed with mast cell cancer in 2024, and conventional treatment couldn’t help her.
Conyngham refused to give up and began exploring options on how to help his sick pet. He explored modern genomic science and artificial intelligence, hoping to get ideas.

How Did Conyngham Help His Dog?
His first step was to analyze the cancer at the genetic level. He contacted researches at two universities and sequenced DNA from Rose’s healthy blood cells and from the tumor. He then compared the two genetic sets, identifying the mutations responsible for the cancer’s growth.
LLM models excel at interpreting huge parts of complex data, and Conyngham used that skill to his advantage. He used ChatGPT and similar AI models to identify targets that the immune system could potentially attack. The result was an mRNA vaccine specifically targeted to his dog and her cancer.
Rose received her first treatment in December 2025, and in early 2026, the tumor was reduced, with Rose looking happier and healthier.

What Are Fans Saying About It?
Conyngham was recently on an Australian television segment talking about his dog and the cure he found. The video was posted on YouTube, and there are plenty of comments about it from happy fans.
Most fans are happy that we have a breakthrough in the cancer treatment for dogs, saying, “This is incredible. Paul you are a legend!” and “This is beyond insane. Game changer!” One fan also hoped that there will be cure soon for her dog as well, saying, “My dog has bladder cancer. She’s already had radiation therapy and it had stabilized, but she’ll probably have to do it again. I really hope they find a cure soon.”
What happens in the future is anyone’s guess. But for one pet parent, AI helped him find a cure for his ailing dog.
The Future of Cancer Therapy in Dogs
Cancer is the leading cause of death in dogs, according to the Canine Cancer Alliance. According to the organization’s statistics, almost half of senior dogs die due to cancer.
While Conyngham and Rose’s case is amazing, we have to mention that this is just an individual case. Not everyone has the same access to money, data and the teams he used to help him come up with a customized vaccine. Plus, even when Conyngham had a design, he still had to get ethical approval and veterinary supervision.
Scientists involved in the project said that it highlights the growing convergence of artificial intelligence. And while Rose’s case is a single experimental usage, it offers a glimpse of hope of how cancer therapies could evolve in the future to help more dogs.
