Husky power

I have two siberian huskies a two year old male called stykes and a 8 month old female called codi…… i have had stykes since he was 6 weeks old, when i got him he stuck to me like glue he has now grown into a very strong dominant dog he is my best friend, and very friendly he has trainded well when it comes to sitiing ,giving the paw and lying down but i have found it almost impossible to teach him how to walk on the lead he just pulls and pulls …he was so hiper that i thought i would get him a friend ,when i introduced codi to him she was 7 weeks old stykes was so excited that he grabbed her out of my arms and start running arond the kitchen with codi in his mouth and i started to panic , he would slap her with his paw and send her flying across the kitchen floor i thought he was jealous at first but he just wanted to play and didnt realise his own strenght till she yelped now the are inseperable and still bite and push eachother around but stykes has calmed down alot which is great he has also trained codi not to rob his food he puts a peice of meet in front of her and if she tries to take it he nips her she has now learned not to touch anyones food … he saved me having to do that training job…… here is a picture of my two best friends
