Older dogs all across America quietly skip their water bowl. See why [X] owners have switched to this cordless fountain that brings fresh water right to their bed.

As dogs get older, they get pickier about their water. Still water goes warm and flat within hours, collects hair and dust, and a slimy film builds on the bowl within days. For an older dog on stiff legs, a long walk to a bowl like that often isn't worth it, so he skips it.

And that matters more than most owners realise. His kidneys rely on a steady supply of water to flush out waste. Vets list dehydration as a risk factor for kidney injury, and the very first risk factor on that list is age. Kidney disease becomes more common from around age 5 to 6, affecting up to 1 in 10 elderly dogs. So when an older dog keeps falling short on water, it puts extra strain on kidneys that are already working harder than they used to.

The good news? There are early signs he isn't drinking enough.
