Sorry to hear about Orso repaquette... so many dogs are ill like him that never should have been born. Orso makes 35 dogs that we know of with epi from these lines.
I'm curious, did Patricia tell you about the epi in the bloodlines when you got him? She insisted to us that she informed everyone of it when they got their pups... I'm assuming not because you had no idea what was wrong with him before you saw Macko's video.
Take care and let us know if you need anything... hugs to Orso from me too!
