Posie had this, too. They wanted to pull her baby teeth when we got her spayed at 6 mo, but I had never heard of it and thought that would be a bit too much for her to handle. It took over a year, but they eventually fell out. The vet said to play tug of war and give her lots of chewing toys to play with. I bought some dog teethers that you can put in the freezer to soothe her gums as she chews. Baby teething rings would probably work the same. The vet said that we would need to get her teeth pulled if they didn't fall out on their own by the time she was a year old. We waited it out. It took about 1 yr. 2mo. She seems to llike the bat-shaped puppy teether. It stands up on its own and she would anchor it with her paws and chew it until it wasn't cold anymore. I bought 2 and switched them out overnight in the freezer. Hope this helps!
