could your pup possibly be a mix, my Lola is a yorkie pom and that's exactly how her tail is, a pom's tail curls up and lays flat on their back. Lola looks more like a yorkie, coloring and everything but her tail is all pom. Personally we think it is her best feature. I have a lot of albums on here so take a look at them, you will see her tail. The pups sound adorable please post some pitures and welcome to YT. You must like it here, because like me you racked up quite a lot of posts in your first month
