I had my dog neutered at a low cost clinic, it seems impossible to keep him "calm" and the tip of the incision site is a little red, but is also trying to scab up; and on the 3rd night I've noticed it looks to me it's opening just a little at the tip. The clinic didn't have too many aftercare instructions... should I be cleaning daily, how can I keep him calm so his healing can start?

If you are still in need of help, try posting this question in the dog section.
Did they give you a collar to keep him from licking the stiches?
