Either it's an OOPPS or they are trying to bring out some hidden recessive gene. If I recall Kellogg which is a few generations back (grand-dam) was associated with pointing labs, but are also associated with the first litters of "sliver" labs. Not seeing health clearances on the Parents; and this is definitely Inbreeding not line-breeding, with all the options out there, and potential risks of breeding this close; One would have to ask why? Still good dogs have been gotten from OOPPS breedings, often for great discounts or free (although most people hide such litters under the rug and only sell on limited). It's not something I'd be into, but to each their own
