If your pooch's water bound this season, I've selected my seven favorite doggie life jackets on the market now. Just like people need a P.F.D. (personal flotation device), don't let your dog be without his C.F.D. (canine flotation device) whether in a boat, or if he happens to take a long walk — or flying leap — off a short pier! While some are for swimming and others for safety, all have a handle, just in case.
