Hi donnaf –
I’m not sure if a change of food will help “wet dog” smell, but Iams is a pretty low quality food so changing would definitely be a good idea. As far as specific recommendations, I’m not sure where you shop, how much you’re willing to spend or what type(s) of food(s) you’re willing to feed (kibble, canned, dehydrated, raw, etc.) – so recommending a particular food would be difficult. The recommended 4 and 5 star rated foods would be a good place to start – you’ll find all different types of foods with all different price ranges so I’m sure you can find something to suit your needs. I’ve personally noticed that on less processed foods my dogs tend to smell better. Since I’ve switched to raw they have almost no odor on their fur or breath.
Now, just for clarification – I know you’re describing the smell as “wet dog,” but does it smell at all like moldy bread, cheese popcorn or fritos? Because that’s a whole new issue. Some dogs (like goldens) who have long hair can tend to be naturally stinky, but a dog with a moldy bread/frito smell may have a yeast infection which would require more specific dietary changes.
