蘇菲是女狗，要注意如果不spay，又不讓懷孕的話，女狗有可能會導致子宮發炎和病變

Q: Should I let my dog have a heat before I spay her?

A: Medically, it’s better to spay your dog before her first heat. It greatly reduces the risk of mammary tumors. People who wait to spay their dogs until after their second heat greatly increase the risk of mammary tumors in their pets. Once they’ve had several heats, intact female dogs have a one out of four chance of developing mammary tumors.
