My Dog Has A Cough What Can I Give Him. If your dog is older and is prone to catch colds, we recommend that you add vitamin c supplements to his diet. This will allow him to breathe better and cough less.
If you know your dog has ingested something and is indeed choking, you can perform the heimlich maneuver if you feel comfortable doing so. If the cough is very bad you can use human cough/cold medications with guaifenesin (an expectorant) and dextromethorphan (a cough suppressant) only such as benylin or robitussin dm. This prevents a dog's heart from pumping blood efficiently.
