Hi so this is my first time posting, I am having a lot of trouble with my 6 month old he is sweet boy but when I walk him he bites me really hard I can tell he wants to play because he wags his tail. I tried sitting down with him and holding him until he calms down but the minute I let him go he won’t stop. I don’t know what else to do. He has it all at home so I’m not sure why he acts like that. Any advice? Please take in mind that he comes from two very strong breeds boxer and husky so his very hard to train.
