According to the American Kennel Club, the level of chlorine in home pools is low enough to be safe for your dog to swim.
Even so, it’s important you make sure that they don’t drink pool water, are kept safely away from any stored pool, and are rinsed off after bathing with clean water.
When your dog is using the pool, don’t leave them unsupervised and make sure they are able to get out safely. A canine life jacket is essential at all times. For extra safety, you may want to buy a specially designed plastic dog pool to help keep your pet cool without deep water.
