The Nauti Dog Designer Doggy Life Jacket provides ultimate buoyancy and high visibility to keep pets safe on the water. It's a smart choice for even the smallest dogs! Constructed to provide buoyancy, along with a cozy secure fit, the Paws Aboard Doggy Life Jackets features an advanced breathable mesh underbelly for proper draining and drying, which provides your dog more comfort and healthier conditions than traditional pet life jackets made with neoprene, which can cause heat exhaustion and chafing. Other features include adjustable nylon straps, quick-release buckles, along with a heavy-duty yet more comfortable Velcro® fastening system around the belly and neck to keep securely fastened.
