I hate it when people say those things. Your Gracie from what I can tell by you sig is one of the sweetest looking dogs I know. What is with the people at your dog park? Here you can take a huge dog like that and all the people will love it. If I saw you I would pick my dog up because she is afraid of big dogs. I would let her get used to gracie. Then she could do whatever. I am glad you won't stop walking. You shouldn't. And those people need some serious education on dog breeds.
