The No Stink, Anti-Bacterial Dog collar in this far out Yellow and Purple Space Dots pattern is made from recycled inner bicycle tubes. Recycled rubber is hand sewn onto the back of the fabric which then prevents bacteria from growing, the collar from becoming sticky and also stinky! Added features on the collar include a Latch-Lock metal buckle fastener, an ID Spot Loop Attach, a handy Pup Top Bottle Opener & a lead attachment. A matching lead in this range is also available. Collar available in two sizes.
