My options around here are rather limited.. I either throw her to the dog park, or avoid the areas all together.
The " incidents" I've had all revolve around loose dogs in the local parks, not necessarily a dog park. She's been attacked a few times, and I don't want to subject her to that anymore.
I haven't seen any dogs on walks, or had the chance to watch dogs in the dog parks. The only park here is not fenced in, and that's why Kira got attacked. We would walk near the area, and Kira would attract the negative attention.
I chose to go there after hours, and let her fetch, play frisbee, and go through whatever training we do.
