This large dog water mat is made of safe and reliable Pvc material. The bottom of the mat is 0.58 mm thick, making it difficult for dogs to scratch, and you don't have to worry about leaks even if your dog has long nails. Let your beloved dog play freely and cool off on hot summer days. Dogs love to frolic in water mats, whether it's the fountain effect or running freely, they'll have a blast. You can easily control the water level by adjusting the water pressure. And, no water is wasted, as the lawn also gets moisturized. Tip: Our connector is compatible with 3/4 inch garden hoses and can be directly connected to the water mat without an adapter. When using the water mat on grass, the water may spray outwards. You can adjust the water flow direction by rotating the outer ring of the water mat inwards. Weight: 4.0 lbs.
