I just got my Corgi puppy about a month ago. He is now 12 weeks old. He is very smart and doing well with housebreaking and basic training, however, he bites CONSTANTLY. Not so much the furniture (though he tries to get at that occasionally) as much as my husband and I. Arms, legs, ears, anything. And, of course, his teeth are ridiculously sharp and painful. At first it seemed like he was just playing, but now if we, for example, give him a chew toy that is appropriate to chew on, he will play with it for about 30 seconds and then drop it and lunge for my arm. We have "googled" how to get him to stop and read many previous posts as well, and have tried everything we have come across, but nothing seems to work. We realize he is just a puppy and (hopefully!!) he will grow out of it, but in the meantime, any suggestions on how to make it stop? And more importantly, WHEN does it stop?! It is very frustrating because we cannot play with him for even 30 seconds without him biting, and it makes us feel like we are doing something wrong. Help!
