ive never heard of that.
I have a pure white pit mixed with a full blooded dalmation and it was in perfect health and lived to be pretty old. so did the parents.
luck maybe?
I do miss my pit/dalmation mix. cutest puppies in the world, they got fat, then they grew up and got muscular and could probably pull a car.
I miss that dog. thats why im tryin to get another dog
