I have a big golden retriever and he wouldent hurt a fly but there is this boxer...

I dont have a pug but I herd about this kind of thing happening before. Well it could be its leash is tight,or he is sleepy and is being interupted.
Oh and tell me how ...

my brother is rough with my dog to but every time he does that I over power him by getting a treat and throwing it out side in the back yard and my dog will go for the treat and my brother will go some were else and leave the dog be.

I have a dog and its hard. But I all so think that he or a dog needs a friend some times
