I can't believe I didn't notice this before with my post about Little Bear. I think he's a bully to Claussen but insecure at the dog park. He barks in any dogs face that wants to play, won't stand still to be sniffed. I'm wondering how I can fix this. Maybe having him on leash? People don't really like to see that at the park. When I held him still to be sniffed so he understood what the other dog wanted he growled and tried to wriggle away. Weird...BC he has never had a bad experience at the park-never been attacked I mean.
I agree with OntarioSheltie and ... it could just be LB's personality... he may just not like unfamiliar dogs. And his behavior with Claussen may be what Dr. Shelli was describing with Ember...
It could also be a maturity thing. I can't remember how old Claussen and Little Bear are (and I know you just posted an update thread about them a few days ago... my short-term memory needs work)... but LB's uncertainty at the dog park, and unwillingness to be sniffed, sounds a lot like Lerwick. Lerwick never had a bad experience at the Dog Park either, but like LB he was scared of other dogs and insecure there anyway. It's just part of his personality. He LOVES people... not shy at all around strangers... but other dogs are a different matter. He used to run away from other dogs (which would only make them want to chase him, silly boy), and really went out of his way to try to prevent them from sniffing him. He became a master of the rapid-sit whenever a dog went in for a sniff.
He has been much, much better since we had him neutered though (at 9 months). He is happy to oblige the bum-sniffers, and will even sniff back. But he still doesn't like it when dogs sniff his face. He is also much better/braver when he and the other dogs are off-leash, generally speaking. When we are walking him, and meet other people walking their dogs, he is much more likely to be afraid and try to get as far away from them as his leash will allow.
He never barks at them, though, or lunges. Fortunately he doesn't do the fear aggression thing. He always flees the field whenever he perceives a challenge (real or imagined). This is especially evident when we're playing fetch with him at the dog park. If another dog comes anywhere near him (even if they're just passing by), he'll immediately drop his hollee roller (or veer off-course if he's still in the chasing stage) and move away a few feet. We spend a lot of time getting our toy back from other dogs, LOL.
