Should my pet have her first heat before she is spayed?

PuppyKissMany people still believe that a dog or cat should have her first heat before she is spayed. This old wives tale! I was in a vet office yesterday, and overheard a young couple ask the vet, “Can our puppy really get pregnant now? She is only a baby!” A 7- month-old baby, so the vet’s answer was YES she can! Dogs and cats (puppies and kittens really) can go into heat as young as 6 months of age, especially smaller dogs and kittens. That’s just one reason so many caring vets are recommending their clients get their dogs and cats spayed at 4 months of age. Your puppy does not need to have her first heat – on the contrary! North Shore Animal League of America points out that spaying, “Risk of mammary gland tumors, ovarian and/or uterine cancer is reduced or eliminated, especially if done before the first heat cycle.”

There are so many great reasons to have your dog or cat spayed by 4 months of age! NSALA not only has a great website listing them all at, their SpayUSA hotline will help you find a low-cost or free spay option near you! See what Ceasar Milan has to say about spaying and neutering in his video PSA for SpayUSA too.
