Bruce and I are a huge fan of the dog park. But we have recently moved and I think he's a little nervous about it. We have been going to a dog park couple of times because we are currently stuck at an apartment until the people in our new house move out so we can move in. I've been bringing my dog agility equipment to the park because I want to make sure he gets his exersize. I've been working with him off leash around a few other "small frail dogs".(the dog park has two area's one for big dogs and one for small its very nice seeing as Bruce gets along better with big dogs) I give him a treat and he totally freaks out If another dog comes by him. I understand he wants to protect his food. But when It comes around to playtime he loves running with other dogs but when he stops he gets really growly and aggressive so I put him on a leash. But I don't want him to be on a leash whenever theres dogs! I want him to be able to run around with the other dogs and not have the other owners be annoyed with me and my dog! Any suggestions?
