Is it safe to spay my senior dog after 6 months of continuous heat?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Female | unspayed | 14 years and 8 months old | 7 lbs

My dog is in heat for 6 months now (just blood, no puss). Recently we did blood test and ultrasound. Everythin was normal but grans, which were slightly elevated (13.3, normal range is up to 12), neut was 11.7 (normal up to 10.5) and eos 1.6 (normal up to 1.5). Vet is unsure whether we should spay her or not because of her age. What do you think, should I spay her or not? Thank you.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Personally, if she has had vaginal bleeding for 6 months that isn't normal and I would spay here. Anesthesia and surgery is a bit riskier for geriatric dogs and cats but as long as blood work was done, safe anesthesia and monitoring equipment is used she should do well. I wish you and Pinky the best!
