Hi,I had Bulldozer neutered 3 weeks ago, and Blossom was spayed the week before. When Blossom came home she had 5 syringes of her pain medicine. The medicine was called Metacam, I don't remember the dose, but the vet said it Tate's like honey, so they like it. They got the medicine once every 24 hours, Blossom was on it for 4 days, she was spayed and had stitches, plus we fixed her cherry eye at the same time, but she didn't need the lat dose, and Dozer went home with 5 syringes as well, but only needed it for 3 days. Both of them acted like they never had surgery, trying to jump, and play, vet said keep them quiet , no running, or jumping for 7 days, yeah right, tell that to a bulldog. Lol. The 1st night Blossom whined, I wasn't sure if she was in pain, or just being sucky, so I let her sleep beside me on the couch in the evening, she jumped off the side of the couch, crazy girl, the next day, I took her out for a pee, and she started chasing blowing leaves, and rolled on the ground, she wasn't being quiet. Dozer was fine too after 2 or 3 days as well. As for the skin after being neutered, my vet said it shrivels up after a while, I don't know how long it takes though.
