Neoprene Dog MaskWe designed this product base on the doggy needs. The one bit of feedback we consistently get is that the gear should be a bit more like the pups: versatile, rambunctious and free. Made of durable and soft to the touch neoprene. It makes this muzzle more an extension of a pup's human face than a simple mask. Bite on the tongue brace to move the mouth up and down. Operation of the muzzle's mouth gives a definite "Rooby Roo" effect to anything puppy says. Easy to clean means pup can sniff anywhere, get wet and messy and get into his special headspace anywhere. Neoprene gives a playful wiggle to the ears. The forgiving material also shapes to fit your glasses. No more having to go into the pit blind. We just have one caution to pups out there: all the other pups are going to be mounting you the second you put it on. Be prepared to scratch, nip and howl.
