My puppy is being very aggresive to all of us. When we play with him he bites us. When we walk past him, he bites us. When we do anything with him, he just doesn't stop biting. He also growls. He bites a face if its close to him.:doh: We have tried to teach him not to but he won't understand. We have tried saying no firmly, locking him in a room for 15 seconds, and spraying him with water, but he won't stop. Could someone please help? Thanks. I also would like to add I am new to this forum.
