Re: Dog Park Problems
I avoid dog parks like the plague. I think they're partly responsibly for Flynn's issues. He went all the time as a tiny puppy and a few times he was really scared by bigger, older aggressive dogs. It made him fearful - which developed into fear aggression. (I have no proof it was the dog parks but the behaviorist seems to think so too).
Now, he's not great with other dogs. He's never bitten a dog or hurt one but given the chance, he has pinned them down, scared them, growled at them. It's scary for the other dog owners and I don't feel right about letting it happen. If it continues to happen it could escalate. You have to do what's best for you and your dog, but I felt too much guilty about being the parent of a dog other dogs and/or people feared so I took him out of that situation.
Flynn has a few select dogs we know he gets along with and that's about it (and we got him a sister last year whom he now loves). Until we got our second vizsla, we felt guilty about the lack of socialization but the behaviorists said "your dog doesn't need dog friends. You are his pack." Of course, this was when he was about 3 years old, so the necessary socialization period with other dogs was already over.
