My 8 month old dog loves other dogs and is very playful. When at the dog park he grabs other dogs by the face and ears & won't let go. The other owners at the park think my dog is aggressive and judge me as an owner. Should I use a muzzle?

I would stop taking him to dog parks, his behavior is not playful it's bossy. I don't recommend dog parks for most dogs and most certainly not for assertive and bossy dogs. It WILL become a big problem for you and your dog. I would read this article about dog parks.

Your dog is either going to hurt another dog or he's going to try his moves with a dog that doesn't tolerate it and then you are going to have a fight.

Socializing doesn't mean you have to take your dog to a park and let him off leash. I would also read this article about socializing puppies.

You might want to take a look at our online university class for basic obedience. It covers a lot of information and includes our video on marker training (The Power of Training Dogs with Markers) and pack structure in the curriculum (Pack Structure for the Family Pet).

I want my dogs to be safe and courteous around people and dogs. Taking them to a dog park & turning them loose is not part of that education process.

We have a number of eBooks that may be helpful.
