Hi guys. It's been a while since I last posted. My puppy Louie has been keeping me busy. Seems his adult teeth are growing in...but they are growing behind his puppy teeth. His top front teeth and his lower canines. Is this normal, it looks so weird, a mouth with 2 sets of teeth. I am a bit concerned, should I take him to the vet and have the puppy teeth extracted or will they fall out on their own like his 4 bottom teeth did???
