My younger sister was also having the same issue as you have but it should be noticed that all dogs do not bite due to aggressiveness only but they will bite out of fear, rather than aggression. Dogs that feel threatened or unsure will respond by biting as a self-defence mechanism. A surprised dog will bite. If you approach a dog unexpectedly or he doesn't hear you coming, his instinct might be to bite out of fear. Dogs that haven't been properly behavior-trained and socialized are more likely to bite.
Hence you can also consult to a good trainer as my sister did. Actually she got her pup trained from Boom Towne and found the good result. Hope for the good things for you too .
