Introducing a new design - Holiday xo !!! This red tartan winter dog collar was inspired by warm holiday memories - colorful lights on a tree, sleigh rides, making snow angels, roasting chestnuts over an open fire, drinking eggnog, the smell of pine, singing in the choir, and wrapped presents under a tree - all those Christmasy memories that I grew up with in a small town in Illinois! Seriously, if you love plaid, I think your pup could wear this fab design all year, but for me it has a special place during the holiday season. Please let me know if you have any questions about the martingale or buckle design... the martingale includes another decadent blue pattern, besides the red tartan!
