He's too young right now but yes Yorkies can swim. Quite a few seem to enjoy it! Jackson was maybe 6 months old when he first was introduced to the pool. Jackson is a water freak... he will go lay down in the ocean at the beach on hot days, or run through it, or dive into the pools... but he hates a bath. Bath time is often different, lol. He will also shake (out of nervousness) in the bath but he's perfectly fine in pretty cold pool water in May.
