I need help. I really don't know what to do. Other people try to play with him or try to carry him and they've been biten. He doesnt run scared and run away from them but when they want to touch him, he bites them. Also, when hes not on a leash and hes inside the house, sometimes he doesnt listen and I tried to physically move him outside the house and he tried to bite me, luckily I saw it coming so I was ready. I don't know what to do. When my dog gets super hyped up and crazy, he won't listen to me, and tries to bite me when I try to get him away from it.
I know as a groomer Maltese can have a nasty streak in them. It sound like no one has ever put that dog in his place and showed him who is boss. He is running the house hold the way he wants. He needs obediance training, and he needs to be on a leash at all times so he can not get away with anything. in a nut shell, he is a spoiled brat who feels he is the alpha in your household.
Illusionmini is right, he is running the show and does not want you in his personal space. He is disciplining you by biting. I have never been in your shoes and I may hear about this recommendation, but I would get on hulu.com and watch some episodes of the Dog Whisperer. He will show you how to introduce you to his space, the body language they read, eye contact, etc., and how to take back your house. I have learned a lot watching his shows and it all works well, and helps me to have more of an identity and compassion for my dogs.
As Cesar says, calm on your part will create submissive on your dogs part. Always relax, don't intimidate, etc. If it gets too bad, like an attack, I would pin him down, use your hand to "bite" him on the neck behind an ear, and hold him there until his body relaxes. This is how another dog would take control in the wild. Some people don't like him, but I find his shows extremely helpful.
He is your friend, partner, defender, your dog. You are his life, love, his leader. He will be yours, faithful and true, to the last beat of his heart. You owe it to him to be worthy of such devotion.
