Why didn’t the owner of the dog put a muzzle (?) on him. I think they are called muzzles, but maybe not. The point is that you can buy and put this thing over the dog’s mouth and strap it to its head, so he can’t bite. It doesn’t hurt the dog. He can breath fine, just can’t open his mouth to bite.

Yes, the word is "muzzle." Very common English word which can be used as either a noun ("Put a muzzle on that dog!") or verb ("Muzzle that dog!"), etc.

Is English your second language?
