Right...I wasn't sure if that was the litter that Sue was referring to? But I don't know of her doing any other brother/sister breeding.
So yes, Ariel is a product of that breeding. The idea was to do a test breeding to see what genetically, if anything, might be brought out. By doing an inbreeding, you can 'expose' recessive genes, and see what you've actually got. You can also set (as in permanantly set) type...but, that wasn't the goal in Sue/Jeff's breeding. In this case, the two "best" "typey" puppies from this litter will most likely be bred on from, as long as they test out as genetically and physically healthy, they will most likely be out-crossed, to bring in different genes. Ariel's brother, George, is quite stunning, and is easily the best looking puppy in the litter. Ariel has a beautiful head, but is long in body, short in leg. Neither one is what we consider a "show dog" 😉
And the litter's sire is quite handsome!.... the dam of the litter, while long in the back and short on leg (like it sounds Ariel is) has a great temperament... both are great to build on the future.... and breeding out from these pups will be great to build on too....
I am pretty sure that would be the breeding Sue was talking about, like you I don't know of any other brother/sister breeding she and Jeff has done.
