On the surface this appears to be a decent food, but when you break it down by ingredient, you can see there are alot of QUESTIONS.
Meat and bone meal is any meat (horse, goat, cow, dog, cat, roadkill, etc) that the rendering plants can get. It's all mixed up in a big vat with the bones and all, cooked down, dehydrated (moisture removed) and then ground up into a "meal". There are alot of unknown fats in this as well.
Poultry fat can come from ANY kind of poultry (Chicken, turkey, guinea, etc). Also, since it is rendered (melted down and processed) it is usually not of a good quality and can even be rancid.
The thing about all the GENERIC terms on the dog food labels is you never know what your dog is eating and can change from batch to batch. Rendering plants get what ever is cheapest and by the way, are NOT government inspected or regulated.
Here is a link for a site by an X-USDA inspector and Veterinarian.

There is alot of other food related info on this site as well (use the links on the right hand side of the page).
The fats in a dog food need to be able to be digested in order to utilize them for energy. Fats that are hard to digest or are not being utilized with come out in the coat and feces, but can also be stored in the liver, kidneys, etc and cause health problems.
I would change foods and give them more exercise. Look for a food with a "specific" fat and also Omega 3 and 6 essential fatty acids. These are GREAT for the skin and coat and also for the immune system and reduce the inflammatory response.
