My old dog has skin tumors. How do I know when to say goodbye?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Female | spayed | 160 lbs

Hello. Trying to decide about care for black lab/pit bull mix about 13 years with multiple skin tumors. Tumor care is good; keeping clean and dry. Antibiotics and pain meds on board. Still eating well, sleeping a lot, still runs around outside. Just worried about open wounds; smell; contagious? Not sure how to make end of life decision. Your help is appreciated. Thank you.

Thanks for using Petco Pet Education Center, formerly Petcoach! I only see cancer patients and as you can imagine, I see terminal cancer patients on almost a daily basis. First of all, sorry to hear about Timmie. Give her lots of love, treats and all the good stuff that she deserves and wants. Usually regardless of the cancer type, I recommend treating any symptoms if they occur. Meaning that if Timmie develops any decreased appetite or nausea or vomiting or diarrhea, these are treated with medications. Otherwise, if you not pursuing cancer therapy, there is really nothing else to do. This decision is hard to make, no question. However, what I tell my clients is to consider making this decision if they think that quality of life has been severely affected. This means when Timmie does not seem to be enjoying herself anymore. You could consider doing it if Timmie stops doing 2 out of her 3 favorite things (that could be eating, playing, running, etc). Best wishes for you and Timmie!
