I do know about the alopecia. I'm hoping they won't be affected dad doesn't have history of it and mom's side doesn't have history of it. So hopefully they take after their parents and have thick long hair and can show like dad.
Alopecia may not show until after 3 yrs of age.
I have never seen a dilute that didn't have half bald ears. I'd love to see photos of the dogs you're talking about, it would be a first for me.
I know blues and isabellas are prone to it I am hoping they will be fine. I think they will be the studs owner has for years been trying to produce puppies that are blue but very healthy she went as far as Japan to try to get this undesirable trait out of this color. I'm hoping all the precautionary measures we took to insure these puppies will be absolutely healthy will pay off
