Feeding my dogs a small amount of canned dog food each day has always been a part of my routine. My guys love it! I might even go so far as to say I think they would totally boycott their hard food if I stopped giving them their night feeding with a scoop some meaty recipe a can. Of course I am careful as to which brand/kind of can food a use (I currently use Merrick), but I do in fact use it everyday. I think I might be in the minority though. Seems more and more dog people I speak to tell me they only feed dry food, day in and day out. Maybe I'm missing the boat here, but I see some definite benefits to feeding wet food too...in moderation.
-adds water to the diet
-increases interest through stronger taste and smell
-easy to chew and swallow for older dogs or dogs with health/mouth issues
