Old dog peeing inside, thin but hungry, has tumor. Is it time?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | spayed | 15 years and 6 months old

My dog is 15 years old. Has a tumor on her side. She is skin and bones yet is always hungry . Eats well, drinks well and does not appear to be in any pain. Still runs around like a puppy now and then. She has never voided in the house yet the past week we have been waking up to puddles. Is it time to let how? my childhood dog started to do this in her senior years and when taken to the vet he said her chest was riddled with tumors and we had to say goodbye there and then.

The decision on when to let Honey go is never easy. From the photos I can see that she is quite thin and appears to have little muscle mass. Since her appetite is normal, it is possible that she has cancer (cancer uses a lot of energy to grow and essentially takes calories and nutrients away from other body systems), but could have other endocrine/metabolic conditions (such as diabetes) or kidney disease. Diabetes and kidney disease could also explain her increase in urination. At this point, I recommend taking Honey to the vet for an exam and blood and urine testing. While none of the conditions I mentioned above are curable, they can be managed with medication that could improve Honey's quality of life. A vet cannot force you to euthanize a pet, but may strongly recommend this as an option if there is a grave prognosis or suffering. I hope this helps and that all goes as well as possible for Honey.
