I know how you are feeling. Roscoe got neutered about a month ago and I was a wreck. THey kept him overnight and I had to work the next day so it was like 36 hours before I could see him. He lost so much weight in just that amount of time, I was so sad. He was ready and rarin' to go as soon as he got home though. It was really hard to keep him calm, especially with Blayne around. He went into naughty mode for awhile because he wasnt allowed to get the exercise he needed to burn off the energy. A month later, he still isnt completely healed. The internal stitches have caused a reaction and he still has 2 few bumps under his incision, which is caused from him licking it. Make sure to keep Cooper away from the incision, even if it means making him wear an e-collar. He will want to lick it so bad because it will itch as it heals. It will heal so much better and faster if he leaves it alone though.
