"I purchased the Waterdog about 3 years ago for my pup. He kept tipping over his outside dish. When he didn't, it was a hot bug catcher. It didn't take long for him to figure it out. He loves it, always has cold, fresh water and is smart enough on hot days to set it off and let it run a minute before taking a drink, so the water's cool. He looks forward to us putting it out for him every Spring. It really does work a whole season on one set of batteries!"
