We have slowly gone back to more canned (wet) food over the past few years. Grady has FLUTD, but hasn't had any flare ups since we started giving him more moisture in his food. Charley has a condition similar to mega colon in people, so he, also, needs more wet food than dry - and a couple of medications each day.

A Vet recently told me that the thinking used to be dry food helped prevent tartar and teeth problems. She says not so much anymore. I do feed them some dry - Royal Canin Oral care. They really like it.
