I have a really cute lab cross pup. He is 5 months and can be very happy and playful and then can just get vicious. I got him when he was 2 months. And he was so playful. He is so spoilt and when he don't get his owen way he starts barking and growling. If I try to give him a tap on the nose he just get's worse and starts jumping up and biting me. But he is great with other people it is just me, my mum , dad ,brother and sister he gets vicious to because we live with him. I love him with all my heart and I couldn't give him away for anything in the whole world I really really love him he is like a baby. But he gets very vicious and then a half an hour later he'd come and start licking you and stuff. Is there any way we can get the vicious side out of him?:confused:??

You must be consistently firm without getting angry. My dog did this and we were told to stop playing and ignore her.

It's also part of being a puppy.

He is not vicious, he is a puppy andthat is how he behaves because he needs a basic obedience class.

My dog did this at first, I was sick of him jumping up and playing at my feet, he was trying to prove he was the dominant one, if I wouldn't give in to his commands he just wouldn't leave me alone, a dog trainer told me to just stand up with your back to the dog and totally ignore him, he will eventually sit down, after a few attempts at this it did work, another way is to put him in another room for a few minutes, its like going in the naughty corner. Hope this helps
