I'd really appreciate any specialist comments about a certain condition.

First a little background info.

My daughter has a 2yr old Working Cocker Spaniel, Mattie, who was diagnosed with Entropian at 8 weeks.

Mattie's a beautiful looking full pedigree who is highly trained, and my daughter has been told by a number of people that if she ever bred from the dog, they'd like a pup.
Up until now that's not happened, because of the condition.

However, she is now having second thoughts. She's not bothered by what she could earn from a pup, quite the opposite. She's concerned that by not having a litter, Mattie may suffer from amongst other things, cancer. On the other hand to get her speyed could result in the dog gaining weight and change her coat quite a lot.

So, what are the chances of a litter of pups also having Entropian ? My daughter is not irresponsible but wants the best for her dog. She's chatted to the breeders of Mattie and it seems that this has been a one off, (these breeders have a very good reputation) as other litters have not been diagnosed with the condition.

Thanks for any constructive comments.
