There are other dog breeds that are occasional hosts to double dewclaws. These include Anatolian Shepherds, Australian Shepherds, Estrela Mountain Dogs, Icelandic Sheepdogs and Spanish Mastiffs.
What breed of dog has double rear dewclaws that should not be removed?
Everything I read about the Great Pyrenees breed stated that the double dew claws should never be removed. The rear dew claws serve a purpose and are attached by a bone, which means removing them is akin to removing a human thumb.
Can dew claws grow back?
Dewclaws will grow back if the germinal epithelium in the nail base is not completely removed..has nothing to do with the bone being removed or not.
