Pet's info: Dog | Australian Cattle Dog | Male | unneutered | 3 months and 16 days old | 17 lbs
Hello, I have a male Australian Cattle Dog puppy who is about 15 weeks old. He seems pretty happy and is friendly towards people, but is protective and dominant as well. The few times we have taken him to a dog park, he is immediately aggressive; small dogs, big dogs, it doesn't matter. He growls, barks, snarls, chases, lunges, and bites, basically scaring them away. He is a little rough with our other smaller puppy sometimes, but not nearly as vicious. Can you help me?

If Hondo gets into a fight every time he's at the dog park it would be best to discontinue going. For some dogs, the dog park is a high-stress place and it may not be for them. Other ways to exercise can include solo walks, fetch in secluded areas, and even focused activities that don't involve other dogs. If he's having trouble with the new puppy, or is severely dog aggressive/reactive it would be best to talk with a trainer or behaviorist in your area that can work with you on a plan to help get him more desensitized to other dogs, and potentially doing OK with some. In the mean time, if play gets too rough or one or both dogs seems agitated, taking a break and separating both dogs until they've calmed down is best. Make sure not to leave them unsupervised together as even the sweetest dog can accidentally injure another! Since aggression toward other dogs is a complex issue, it is best to work with a trainer who can supervise your techniques and plan in person.
