I have taken Brennan to the dog park near my house; however, I will only do so if there are absolutely no other dogs there. No chance in risking a fight, but it helps him burn off energy since we don't have a fenced in yard.

If there are other dogs there on the large dog half of the park, absolutely not. That's too much risk for Brennan.

Lily has never been to one, but we used to take her to a baseball field and let her run when she was younger. Now, she just doesn't care. She's happy with a small walk around the neighborhood.
