Keep your dog's paws safe and comfortable with WagWellies® Dog Booties. Ideal for rainy days and outdoor activities.  WagWellies®, the original wagwear wag "Wellies" or “Wellington” boots are 100% rubber, slip-on puddle jumpers that are built to last. The open-vented slits make them a breeze to slide on, while also creating a secure fit that will stay put even while on the run.  This patented design is sleek, sturdy, and, most importantly, comfortable, making for the perfect paw protection.  If you're looking for a hot and dry weather paw protection, checkout the wagwear Mojave Booties. Note: Getting a dog used to wearing boots is a process. It is very normal to see an amusing high-step in the beginning. This is because they can’t feel the floor and it throws off their coordination, they need time to re-coordinate themselves. It may even take getting them outside and on with the walk before they start to realize that they can in fact walk & run as usual.   Fit:  The WagWellies® should fit snug, they can even need a little squeeze to get on. Although it might be a stretch to get through the opening-the paw spreads out in the cavity of the boot. Less movement means more comfortable for your dog. It will feel more natural and there will not be any excess weight on the paws. Position the strap under wagwear label to keep the front flap from moving. Sizing:  Weight is just approximate in the size chart below - the best way to size your pup is to measure the paw.  To measure the paw length, place your dog's paw on a sheet of paper and mark the back of the paw pad and tip of the longest claw.
