I had a female (not a yorkie) who we didn't spay until after her first heat. That first heat was enough to convince me that she needed to be spayed. She became neurotic! She was horrible while in heat, and she was normally a very sweet dog. She wouldn't listen, she would try to take off when we were outside, she even bit my hubby once and all he was trying to do was get her to go outside to potty before he went to work. She didn't want to leave me, so she bit him. After she got spayed, she was much calmer and back to her sweet self. Plus, according to our vet, it helps decrease the risk of cancer. |
