My husband just noticed that my 5 month old yorkie "Chewy" has two rows of teeth on both the top and bottom of her mouth. He keeps saying that Chewy was inbred. Does anyone know if that's true? I've never heard of two rows of teeth on a dog before. Kinda freaky, reminds me of sharks.
It isn't because he's inbred, though certainly you could prove it for sure by looking at his pedigree if he's AKC registered. It's actually just a common dental issue (especially in toy dogs like yorkshire terriers) where his adult teeth have grown in, but he hasn't lost his puppy teeth yet. It even happens in humans sometimes.
Unfortunately it's a condition that will require your veterinarian to anesthetize your dog and remove the teeth. You can't leave both sets in, because puppy teeth weren't made to be permanent teeth, and they will get bacteria, rot, decay and possibly cause your dog to get mouth absesses and such if left alone. Fairly nasty stuff, really. As it can be pretty scary to have your dog anethetized, most people have them removed at the same time they have their dog neutered so their dog doesn't have to be put under on 2 separate occasions.
Never trust a tall dwarf... he's lying about something.
As already mentioned, this is VERY common in toy breeds. My male minpin retained his lower baby canines, but did finally lose them a few days before the appointment to have them pulled, but he was almost 14 months old and they actually should have been pulled earlier. My female minpin had 8 baby teeth pulled when she was spayed at 7 months. It is really common to have any remaining baby teeth removed at the time of spaying or neutering...it is generally quite inexpensive to have it done then since the anesthesia is a major part of the expense involved in this type of dental work. Doing it then also means one less time having to be put under, which is also a good thing since there are always risks associated with anesthesia.
Both my Yorkie x Maltese retained baby teeth when they got their adult teeth. The oldest needed 2 removed at the time of her spay. The vet recommended leaving her as late as possible to spay her so he could remove them all at that time instead of spaying her at 6 months..remove a few teeth..only to have to put her under again a few months later to remove any additional teeth that would still remain when more adult teeth came in. She didn't even start to get adult teeth until she was just shy of 6 months. The youngest eventually lost all her baby teeth on her own by the time she was 8 months, but I agree it turns them into little land sharks :)
