I have a 10 week old puppy. He has plenty of toys gets full run of my back garden (he can't go out on proper walks as he has not had his second vaccination yet.) He has these mad times when he will run around and bite anything he can get his teeth into including hands,feet, arms, legs, faces. He is biting really hard and drawing blood. He also bites feet and ankles as your walking past. I have tried some different things ive seen on the internet such as making a loud sound., ignoring him, saying no loudly, giving him something else to chew on etc (I have never ever scorned or cruelly punished him!) Is this something other people have experienced and will he grow out of it or will I need to take action to take away his bad habit?? When he has all his vaccinations we do plan to take him to puppy socialisation and puppy classes.
