No, she's not going into heat - she was spayed last February. I guess I can live without her playing a lot like before or but I kinda miss the snuggles that used to be given so freely. I guess I took it for granted that she'd always be that way because I didn't know, I never had a dog. Now when she snuggles I make sure it lasts as long as possible where I'm not the one to move first.
