My last litter of dogs produced two pups who were the average of the line, and 2 others that are significantly larger than just about anything we have bred to in 22 years. My hunch is that the line is starting to overcome the tendency towards filial degeneration, and is actually increasing in vigor because of stringent selection and overall improvement of the line. The other possibility is the skip in generations that I have noticed in the line, and that these dogs are a direct throwback to something deeper than 5-6 generations before we were breeding them. These pups have a 44% Inbreeding Coefficient. The next mating I do, will have a 72% inbreeding coefficient. It will be interesting to see what percentage carry this new larger frame size that has cropped up.
