Our rescue dog, Ivan, has some oversized features, a function of breed mixing. His background report claims he is a chow chow mixed with a Siberian husky, also known as a chusky. I don’t think so–more breeds were involved in the parents. Regardless, he is a great dog, a gentle giant, most of the time. But his breeding has given him a tongue and a tail that are oversized as shown in the photos.
