This is an interesting and informative podcast from Pure Dog Talk.
Victor Stora, Shetland Sheepdog breeder, AKC/CHF Residency Recipient and Veterinary Geneticist at University of Pennsylvania, shares concrete information on breeding for type and consistency of style while keeping a low COI (Coefficient of Inbreeding).
Stora observed that many breeders fall in to one of two categories.
“People might fall in to health testing too much and losing type, or you have people ignoring health because they’re getting the type they want. The happy medium is where people should be,” Stora said.
