Ask a Dog Vet and Get Answers to Your Dog Veterinary Questions
Hello, I am sorry to hear about your dog. Thank you for requesting me. Is he eating at all? Do you happen to have copies of his blood test results? Was a biopsy done on the tumor at all?
Generally, I think if a dog is not eating, his quality of life is not good, and it may be near his end. If he has an inoperable tumor, that makes things even worse.
Only you can know when it is the right time to let him go, you who know him best. But when I am asked for advice, I tell dog owners that when he stops eating, he may be ready to leave this life.
