My Dog Learn To Swim.

Start in shallow water with your dog on leash, ideally, where you too can enter the water. Wade in a few steps and encourage your dog to follow with some tasty treats. Reward him when he steps in the water,
When your dog is two to five months old, you can start to teach your dog to swim. At that age it will have the strength and endurance necessary for its first swimming lessons. Do not throw a dog that is new to water into deep, cold water and expect it to automatically swim.
