One more question to add on (sorry so many
) . . . I know that teething is completely normal for puppies, but do you ever punish for biting? At a certain age, if it's excessive, etc? His teeth are not very big, but they can be pretty sharp! I let him chew on my finger and play tug a war with it, but now when I'm laying on the ground playing with him, he'll latch onto my nose and try to play tug a war with my nose! He also has made me and my boyfriend bleed from tugging too hard! I don't mind at all, but I'm wondering if he should ever receive a stern "NO" for doing it or if I should just let it happen?
Thanks again!
