I did the same (sort of) with Drogo. When he was a bit younger, he ALWAYS bit our clothes when we arrived home and he did the same thing with strangers when they tried to pet him. However, it did get better in time - naturally, mostly, and with a bit of our help. When I arrived home, I would show him a yumy treat and made him sit and wait. Then, I would put the treat on the floor and let him wait some more.
After I allowed him to eat the treat, he would no longer be super-excited to see us, as he would be busy smelling the floor for some more treats, lol. Now, he has a tendency to jump on us, so this is our new challenge. BUT he no longer bites our clothes, yey!
