I've submitted a thread about a week or two ago concerning Buttercup not barking, whining, etc. I took him to the vet today to get his shots and right after we walked out the clinic, he started barking at 2 bulldogs that were outside. I was amazed because that was the first peep I've heard from him ever since I got him. Now that we're home, he's constantly barking. I'm getting frustrated because I want the barking to stop and my son (2 years old) thinks it's hilarious when he barks and encourages or do something to make him bark just so he can have a good laugh. What can I do to stop the barking? (There is no way in telling my son to stop encouraging Buttercup, it's his way or NO way and that's my fault)
