It's okay if your dog doesn't like other dogs. All dogs are good dogs, and that doesn't make them bad or you a bad dog owner. What is questionable to me is making the decision to bring your dog -who doesn't like/is agressive to other dogs- to an off leash dog park. My understanding is we take our pets here so they can all play together and socialize. Lately my medium sized dog has been bullied or attacked by a smaller dog. Leading to her getting defensive, because she's bigger or louder I'm always seen as the villain or she's seen as an aggressive animal (heartbreaking cause she so submissive and sweet). All dogs are good dogs, please leave your anti-social ones out of the dog park (they clearly don't like it very much). /Rant
