 The Kuvasz has a very efficient metabolism and is predisposed to rapid growth—vitamin supplements are not necessary and, in fact, should be avoided.Cooked bones should never be given to a Kuvasz or any other dog because the cooking process renders the bone brittle and prone to splintering, which can cause serious injury to the dog's mouth and digestive tract.It is important breeders screen their breeding stock for common inherited disease for Kuvasz as recommended by the Canine Health Information Center.
