[matese]

everything 107barnbey posted plus not spaying can cause Pyometra infection in uterus, if not detected early infection causes puss in uterus which could erupt, causing puss to get into blood, which can cause DEATH. If you mate her one time all the above is eliminated. If you are not going to mate her spay her. At one time they advised spaying after females first heat, that was changed to spaying BEFOFE FIRST HEAT, so age is not a factor, usually females go into heat about 6 or 7 mos. Speak to your about proper time. My first 2 yorkies I did not spay due to ignorance of Pyometra, my 3rd and 4th yorkie I had sMy 2nd payed before first heat as advised by my vet. My 1st 2 babies came down with Pyometra first one was age 11 y/o it was full blow (the vet I had at that time is not the vet that I have been with now 20 + yrs ) I took her to the vet because she had a foul odor coming from her, I thought it was a urinary infection, turned out t be full blown Pyometra, vet gave her a full hysterectomy, she died 9 days later. 6 months later my 2nd baby 12 y/o came down with it, again it was a foul odor, I took her to a diff, vet, they operated, operation was successful, but she died 6 months later reason not known, but was not from Pyometra. My 3rd baby died from a bad heart at age 13 and my last sweet heart died at 16 y/o from pancreitis, spaying my dogs did not change their personalities at all, they were energetic, playful , healthy appetites, sweet loving babies. I recommend spaying if you are not planning on breeding your female. I also had a poodle that I did not spay she had many tumors all removed when discovered, she died of breast cancer at age 11 y/o. Do not fear, if you are not going to breed PLEASE spay her. Check with your vet as to the proper age & time. Good luck and enjoy your lil baby, yorkies are a awesome breed.
