Mini Schnauzer gets extremely protective at the dog park
I have a 3yr old Mini Schnauzer. He has been neutered and is a great dog. Lately, I have noticed that when we are at the dog park and other dogs approach me looking to play or for affection, he gets extremely upset and barks at them scaring them away.
Sometimes, he gets aggressive and I have to pick him up and remove him from the circle of dogs for a short while. It is embarrassing. He wasn't like this before and I think he acts this way because he senses I am sad. Please help, I want to understand why my dog does this and correct this behavior but I don't know how.
NOTE FROM LINDA AND MAX: How old is he - is he going through his 'teenage years' where he is trying to establish himself and pushing the boundaries? Or has he had a bad experience with another dog which has frightened him?
