Most Golden’s love to swim, and it’s excellent exercise for them, even when young. Introduce them to water and let them explore on their own. If they are unsure about the water, you might get in and swim out a bit to encourage them, but let them take their own time. Younger puppies might be more standoffish to water than they would be in another month or two; that’s normal. Never toss a dog into water that doesn’t want to go in! Sometimes a water crazy older dog is perfect to have along to help teach your dog to appreciate swimming. You might also try tossing in a toy for him to get, but be prepared to go out and retrieve it yourself if he doesn’t! If you have a swimming pool, just remember that the dog hair in the pool will mean you need to clean the pool more frequently if you dog goes in it a lot. Be sure that your dog knows how to get out of the swimming pool; it’s not a good idea to leave him unattended with access to the pool.
