Hi, It has been a decade since I had a pup around the stead and this new one seems a bit different LOL. This pup (Maltese and terrier of some type) is almost 5 months old and about 8.5 pounds. She seems to be getting her grown up teeth but it looks like the new teeth are coming in right next almost on top of the puppy teeth. So it looks like she has two extremely close together very sharp teeth. Is this normal?
