I don't know how to explain it other than it's not his normal doggie breath. It may be nothing but I don't know.
The bad breath and the coughing may be connected. Dogs with bad teeth or infections in their gums can develop a cough and other infections, sometimes very serious.

Has your dog had it's teeth checked recently? It may be time for a dental cleaning. Sometimes other illnesses can show with signs of bad breath. If it were my dog, I'd take it to the vet just for a check up anyways and also have the teeth checked. It's always better to be safe, than sorry.
