... your dog is so lively, it's like this when you get excited! As soon as I bite my clothes and pants, I will scold it loudly and yell at it when it is still in its mouth. If it acts as if nothing has happened, it can only pat its ass when biting, and then loudly scold it not to bite! After a long time, it will know from your attitude that you will not let it do anything!
Prepare a dog with bigger chewing gum and give it a plush toy! Let it gnash its teeth and vent its anger!
