This dog pool is made of safe and high quality PVC, which is non-toxic and durable. You can fold up the dog pool and put it in your trunk when your family wants to go to the beach to play. The swimming pool is not only suitable for pets, but also for your children. In the hot summer, when pets and children can cool off, it is comfortable for them. There is a valve on the outside of the pool to allow you to quickly and easily drain the water outside. It's big enough for you to put balls or other toys in the pool.
