we have a 6yr yorkie that weighs between 3 1/2 and 4 1/2 lbs. we have been debating on wether or not to "fix" her or not. she has not ever been pregnant and we do not plan on breeding her. she is our baby, since we can't have any of our own. i was told that if we don't spay her, her female organs can turn up cancerous. she is healthy, no major porblems. check ups have always come out clear. the only real problem she has is dental problems.
she has been anesthetized twice, both for teeth cleaning and removal. both times it has taken a day or so for her to recover from the anesthesia. we hate to put her to sleep for this procedure if spaying is not really necessary. any advice would be highly appreicated. THANKS.
Spaying does reduce the risk of mammary cancer pretty dramatically.
I would wait until you plan to have her next dental cleaning done and have the vet do both at the same time - the spay and cleaning - that way she only has to be put under anesthetic once.
The bigger risk, I think, is that every heat cycle she goes through runs the risk of Pyometra. Pyometra is a uterine infection that can potential kill a female dog is not caught quickly and the only cure is spaying - which if your girl is already sensitive to anesthesia would be even more physically stressful for her. I've had 2 Pyo's and they are NOT fun. The girl spikes a really high temp, and the toxins from the pus in her uterus are basically slowly poisoning her. It's scary. And if you don't know to check her daily for several weeks after each heat cycle you can miss the early warning signs.
