Depends on who you ask Yes, it is cool to add canned food. Your going to get different answers but I mix in canned food because of the moisture content. I don't feel giving a dog a bowl full of dry kibble is sufficient enough for what they need and I have read articles about it that makes alot of sense if you actually think about it. A dry kibble has 10% to 12% moisture and canned food food retains 70% if not more which is more of a species or biologically appropriate diet. Some say you can just add water to there kibble but I'd rather add a can of wet meaty food. This is my opinion and not trying to change anybodys way of thinking but you do what you feel is best for your dog. Personally, I feel that canned food is beneficial to a dogs diet. Here is an article to read Food for thought so to speak lol! No pun intendedis it cool to mix wet n dry food?
