Sounds super basic, right? And unnecessary since every dog knows how to doggy paddle? Nope! Don't rely on that assumption. Take the time to get in that water with your dog and ensure he knows how to stay afloat. Even if your dog is terrified of the water and you think that he'll never go near the pool, don't take that chance. There are dog trainers available, too, to help you teach your dog if you don't think you can.
