When I got my female yorkie Dixie spayed and also two teeth removed and microchipped the vet said to keep her from running and jumping. Well I gotta tell you I did try and sometimes she would stop in the middle of her 120 miles per hour run and look at me when I got that scared look on my face. She did just fine and when my twin daughters got thier male yorkie Teddy neutered, microchipped and four teeth removed he came home and never stopped as well. I would not worry so much about your little one. It is problely better to see them playful and feeling good than limp and not. I think they will stop if they hurt. Good Luck, the neutering is so much easier, at least Teddy did not have to go back to get any stiches out, Dixie on the other hand did have staples and did have to go and have them removed. The vet told me he knew she would be "very" active so he chose to use strong staples instead of sutures. They are both fine now and glad it is all over. I was the nervous wreck, I wanted to camp out in the lobby of my vets office for the two nights my little Dixie was there.
