I know the pain and anguish that comes from losing a dog so I will pray for your four legged friend. But I will say this. If worse comes to worst the easy way out for a lot of people would be to just “put it down” and get on with your life. But you can do better. Clinical trials are conducted all the time for dog cancer therapy just like they are for humans. You could enroll your dog in one of these trials. Your dog may or may not benefit but the data gathered from these trials will benefit dogs as a whole in creating new treatments and therapies. And you can take comfort in that. Google ‘dog cancer clinical trials’ to see if there are any in your area or ask your vet about it.
