Hi I think it stems from a recessive gene, that pops up in our breed, but since the first time we had a pup with
rear dew claws, its the first thing we look for when the pups are born, they are easy to miss
as Norwich are so small when born, have never had them it appear again in any of the Matings from them pups, but they could well turn up a few more generations along,
ps
yes I would remove the dew claws, they are a nightmare sometimes, I have a little Bitch I bought in off a friend
a few years ago with her dew claws still left in and when grooming or trimming I often forget and catch coomb in them,,, The LOOK SHE GIVES ME COULD KILLL smileeeeeeee I say sorrrrry babe I forgot,,,,
