A happy, socialized, well-trained dog that gets love and attention is much less likely to bite. This is true for any breed. Statistics show that the dog that is most likely to bite is an unneutered male that is kept in an enclosure with minimal socialization. So, whether you have a little lap dog or an 80-pounder, the time you spend in play, exercise and training is important. Scolding or hitting a dog for bad behavior will not correct the behavior and will make your dog afraid of you and other people.
Dogs often use their mouths during play.
That may be OK when they are playing with another dog, but it should be discouraged when they are playing with people. Buy your pet a good chew toy and, if he tries mouthing you during play, redirect his attention to the toy. Or at the least, stop playing with him if he tries chewing on you. Only begin playing after he lets go. Take your dog for walks and introduce him to other dogs.
