Jasmine: How to stop my Bullmastiff puppy from aggressively biting?
She is 8 weeks old and has been biting aggressively the 2 weeks she has been with me. She goes on attact mode and will bite any part of the body. She bites as long as she is awake. I’ve tried yelping and staying calm and tell her no, also tried to be dominant. I had to show serious aggression for her to stop. I don’t hit her. I don’t want to be aggressive to control her. Anyone familiar with Mastiffs can give me advise?

First of all, your puppy is not biting aggressively. She is biting playfully. Big difference.

Keep her on a leash and use a leash correction when she bites then redirect her towards something better.

    Chances are she is just play biting like she did with her littermates. At what age did you buy her at? Was she with the other other littermates until the 8th week? How was the temperament of both the dam and sire?

    I have seen puppies that young and act like they want to take you out. I totally disagree with the dominant theory. You will end up with more problems than what you have now. You never solve aggression with aggression. What will you do when she grows into a very powerful over 100 lb. dog? My rottie weighs 145 lbs. and the last thing you want to do is pit your strength against him. There are alot of other things you can do, like setting up rules and boundaries. If you tried the yelping, just doing it afew times probably isn't long enough to get the message across. But if it is causing your puppy to become more out of control, then stop using that method. You can add to that, by throwing a fit looking up at the ceiling and walking out of the room. (oh, when I use my teeth, it causes her to go away) When you return to the room act like you are wounded. Normally tho what I do is that I always stay in a very calm state of mind. I just calmly tell them, "Too Bad", take them to the kennel for time out. I take out the bedding, toys, etc. I am not yelling, throwing them in the kennel, so they will not associate the kennel with being a bad thing. Any other time, I always give them cookies for going in. Consistency is the key. If you haven't ever had a mastiff before, I recommend that you find a trainer to work with you that has worked with the breed, uses positive reinforcements.

    It is a myth that playing tug a war will cause aggression. It is really old school stuff. I did not wrestle play my rottie, and I wish I had. Because if you try to play with him now like that, he will growl at you. I don't mean get onto the floor and do it of course.

    I think your dog needs to learn the Be Still Cue for sure. There is a book by Brenda Aloff, called Get Connected with your Dogs. Emphasizing the relationship while training your dog. Its a big book, and it comes with a DVD of 90 minutes. I just went to her second 3 day seminar last month. She is wonderful. It is so worth getting the book. has the cheapest price and there was no shipping charges. I think it was $ 32. I train dogs and use her methods.

    This is the time right now to be training. Do not wait for your puppy to get any older. Get this training into her little brain while she is this young. Brenda Aloff also works with aggression dogs.

    Good Bite-Inhibition
    Good bite inhibition does not mean that your dog will never snap, lunge, nip, or bite. Good bite-inhibition means that should the dog snap and lunge, its teeth will seldom make skin contact; should the dog's teeth ever make skin contact, the inhibited "bite" will cause little, if any, damage. Ian Dunbar

    So if you do not work on the biting its going to be a dangerous combination. So to say to never ever let a puppy play bite, I totally disagree. I like what Ian Dunbar says in his book, After you get your Puppy. I rather be around a dog that was trained on biting, then with a dog who was never allowed to do it. Because if all of a sudden this other dog goes off, you have some serious damage from his bite compared to the dog who was trained about the biting.

    You are doing the correct things but you are expecting an infant to behave like an adult. Just continue telling her that hurts by yelping loud and taking yourself away from her. Stand up and turn your back and fold up your arms out of her reach and even leave the room for a time. Bitting gets no human company and no rewards.

    Be sure she has lots of things that are OK to chew and encourage her to use them.

    Since she is going to be a BIG GIRL don't teach her things now… that will be a problem later. No teasing or staring at her. A straight look in the eyes is an aggressive motion.

    Be sure to massage her all over her body. She will enjoy it and it should calm her and it helps to socialize her. There should be no part of her body that does not belong to you and can be touched.

    good luck with your baby elephant

    When you have puupies you should NEVER and I mean never let them put their mouths on you. Even if they are just playing. Because when they get older they become really aggressive and end up using their teeth. But the way you stop it is, when ever they mouth you just correct them and immediately stop the game for a few minutes.

    you must be crazy he is a dog and he is a baby they are going to bite and in time those razor sharp teeth will fall out and the need to chew on you will go away

    Puppies at that age are trying to figure out the difference between aggresion and playfulness, they do not know there own strength and will bite harder because they dont really know any better, i agree with the other guy, use a leash as correction, say owe with it, thats what i did, and now when my dog is playing, and he bites, not even hard, if i say owe he immediately stops and looks at me. to be dominant you dont have to be aggresive, turn on some good ole Cesar Milan, Dog Whisperer, he will teach you lots!
    Good luck!
