The collars ~ hand-felted in high-quality 100% wool, decorated with imported ceramic Peruvian skull beads, and lined in 100% cotton fabric ~ come in 1/2″ (for tiny dogs) and 3/4″ (for medium-sized dogs) widths and have safety parachute buckles and D-ring for the dog’s ID tag. They’re durable and long-lasting (Willie has been wearing his for over a year!), and a real conversation piece, especially if you have a tiny bruiser like mine.
