Here`s another great article:
I took my puppy to a dog park, he is usually good with other dogs and playing, but today one of the other dogs plays a little rough, his hair stood up on his back and his teeth were exposed and he was snapping at the dog, the other dogs rough playing set it off but how can I train him to be less aggressive, an get less riled up? He seems to only be doing this out of fear when he thinks the other dog is playing too aggressively ( other dog is just playing normally)
