When I bought my corgi I was told he was red Merle. He has blue eyes and Merle marbling in his coat but for the most part he looks 100% red now that he is 2 years old. He got my pure pembroke female tri pregnant and she had 8 puppies, 2 tri, 2 sable, 3 red Merle and 1 blue Merle. I sent in a DNA test for both the dogs to see if they had any health conditions and I wanted to see how much cardigan my red Merle had in him. The results came back with 100% Pembroke Welsh Corgi. Everything I have read has told me that is impossible. How can I get these results? He has the Merle gene present in his results. I got the test done from wisdom panel and they have said they are 90-99% accurate. Can anyone explain to me how this could happen? Thank you.
