Since 1970, Four Paws has been delivering the highest quality products to simplify pet parenting and help our furry friends stay happy and healthy. This Wee-Wee Premium Patch Pet Potty gives your dog a clean, convenient, and comfortable potty that is perfect for indoor or outdoor use. From puppy potty training to offering your adult dog a dedicated place to go when you're not home, this dog potty patch is ideal for a variety of scenarios. The Premium Patch is designed with Easy Clean Home Technology, so there's no need to worry about leaks or messes. Just place a standard-size Wee-Wee Pad or Premium Patch Washable Pad in the dog potty tray for a seamless fit and let our absorptive Leak-Guard System shield and protect floors. When it's time to clean up, the Premium Patch's non-stick surface will make the task easier than ever! This pet potty patch also includes an optional quick-dry grass mat to give your dog the feel of lush grass under their paws. Need a larger potty area? No problem! You can add the Expansion Kit (sold separately) to continuously expand your dog's potty. Simply lock the tray panels into place—there's no limit to how many you can add! The Premium Patch Pet Potty is 24.5 inches by 25.7 inches and recommended for dogs up to 50 pounds.
