Last month while at the dog park Spike met an 8 month old boxer and realized that if he growled and nipped at the boxer it would run. He went nuts herding this poor pup around the dog park nipping at his heels his. The owner left after I tried to explain he wasn't trying to hurt their dog. But I can understand he was getting pretty loud with his play barks and growls. Now whenever we go to the dog park he trys to get any boxer he can find to run away from him. So he barks, growls, snaps his teeth, and nips at these poor boxers until they run away and once they stop running he starts all over again. Everyone I meet thinks he is being too aggressive but I try to explain that its how he plays. I don't know what to do anymore cuz I hate people thinking that hes being mean. I try to explain that at my house when Spike and Annie play it sounds like they are killing each other but they are just playing. Any other corgi owners have this problem its not the dogs it the people who don't understand. Im a dog trainer I know dog behavior and body language and he is not being aggressive but I don't know how to convince people at the dog park of this. Please help!
