I agree that crossing these breeds can’t be right, especially for stupid amounts of money. Our Zack was the result of an accidental mating between a JRT (the mum) and a BishonFrise (obviously the dad!) there were three pups and all had different charactoristics of either parents.
Zack as you might have seen from his picture looks more like a rough JRT. I spose if we were to give him a cute breed name it would either be a Bishon Russell or a Jack Frise?! He has is mothers habit of running in a straight line in the opposite direction if let off the lead and his fathers stuborness when being trained!!
