we have two 9 mth old husky pups and they pull like fuck(as its their job)
we tried a class with them and they were spot on in class!heeled,came to us etc but in the outside world they were back to normal, we now have an army trainer coming in to help us train them tbh its more about training you two before the dog.

oh and those holties are shit for our dogs.we use chain chockers and they still pull like mad.
