It depends on which wet and dry foods you choose, or are comparing. There are good and bad, high and low quality versions of both. However, it is fair to say that wet food has the potential to be significantly better than dry. And the "best of the best" wet food is, IMO, a million miles better than the best dry food on the market.
The reason is quite simple. The best canned foods you can get are comprised solely of meat/offal/bone - and water. There isn't a kibble in existence (and never will be) that isn't loaded with a heap of un-neccessary grains or starchy vegetables. They're not in there because the dog has any use for them though

They're in kibble because they're cheap (as compared to meat) and because you can't make kibble without large amounts of starch to stick it together.
Canned products also win on health grounds. Not talking about the composition of the food (i.e. ingredients) in this case, but the fact that it's dehydrated. Fully dehydrated diets are increasingly being linked with a range of health problems...QUOTE]
Thank you! We went and bought the Wellness Super5Mix last night and he seemed to enjoy it much more than the stuff the breeder sent home with him. I think we're going to try mixing in some wet once he gets used to this new food.
As new puppy-parents we appreciate the advice so much!!
