Usually they are not in pain. Oh boy I remember Maxi's first fallen teeth
Its seemed to me that the first ones that go are the front teeth the little ones
Then it was the time for the molars to come out. Maxi still has one canine tooth that is a baby tooth and never came out so it will be taken out when I ll bring him for neutering. You gonna find a lot of teeth laying on the floor here and there
Just check your pup's mouth periodically to make sure all the teeth grow even
