Actually, I was kind of thinking the opposite way. I wanted to take Lexi to a dog park to help with her dog aggresion, I guess not anymore. If lots of people hate it when other's dogs are aggresive. But I'd keep her on leash with a muzzle. I can't think of anything else, training classes never worked, sigh, if only she was friendly, but there is a reason for her aggresion.
As a pup, the vet told us TO NOT expose her to ANY dogs of any sort until all vacines were done. Well, by then her socialization period was well over and we lost all socialization skills....:(
