Good for you!! It's good to see another responsible pet owner.

Our vet will spay as long as they are 5 months or older, of a good weight and healthy. We found with Peach that some dogs go into heat a lot earlier than others. We didn't get her spayed quite quick enough and she went into heat at 8 months. Really caught us by surprise - we had to kennel her dad for several days until she could be spayed and recover for a day or two.

With Molly and Carly, I didn't give them a chance - they were spayed between 5-6 months which turned out to be much better for them. By doing it when they were younger it helped them bounce back much quicker.
