Hi Tina no sounds like Boone is right on schedule, also last week at class Kelly mentioned to the group that even though puppies loose and get all their teeth in it takes many months for them to grow all the way in so until they are about 18 months or so depending on the dog it can still bother them and make them be chewers as we all know the chewing helps relieve the pain and itching that they feel even after the teeth are in.
