When Shayker was a baby, her adult teeth came in and she had 2 rows of teeth. Looked like a shark. The vet said he would remove them when she was spayed. Unfortunately, Shayker was diagnosed with renal failure and we never had her spayed. She died at 14 months. You pup will be fine with the double teeth. Not a big deal, just enjoy the shark smiles..
you will probably have to have them taken out though...
