We are not planning to breed Gracie. Our vet wants to wait as long as we can before spaying her. With my previous dog, they wanted her to go through one heat cycle. I remember having to put pants with a pad on Teddie! I don't think they are planning to do that with Gracie. I remember Teddie getting very sweet and clingy when she went into heat. Gracie has been a little like that lately. She is only 4 months though so it is probably too soon. Every vet has different thoughts on this. When did you get your pups spayed?
