Whenever I take my dog to the park, the following happens:
- When a dog barks at him, even if it is a small Chihuahua, he immediately gets scared and jumps back.
- Otherwise, he just plays normally: running around with the other dogs, fetching a ball, etc.
- However, whenever there is a shy dog, usually if it's a 5-8 month puppy that makes a lot of crying sounds, my dog immediately runs over and rough houses, mounts, etc. Today it got a little out of hand and he bit another dog's(8 month old husky) butt. It was quite a struggle to pull him off. Luckily, nothing happened to the other dog and he was fine. Maybe that triggered him? This other dog was continually letting out crying sounds.
I was told that dogs don't suddenly do something like biting. It's usually a longer behavior pattern. I don't want him to behave aggressively towards shy dogs and so I would like to know the best way to train him against this.
He never ever barks at home. I've heard him bark just once at the park when we had to leave and he didn't want to go. Otherwise, he never barks, I've absolutely never heard him growl or pounce on any human. He doesn't lick either. And I take him to the dog park almost every other day, and he's never bit another dog. So to me, this really was a first. Any advice would be super helpful.
His current training: He's really good with sit/stay/come. I can usually immediately re-direct his attention and he comes when called. Also, he never pulls on the leash. Although the "re-directing" part didn't work too well when he was biting onto the other dog.
He's a 70 pound American Staffy. They estimated him to be about 3.5 years old. And he is desexed.
