Q. I cannot afford vet care. Can I treat my 13 year old dog for kennel cough with OTC meds?
A. Not really, he/she needs antibiotics. You can try to nebulize her at home or even run the shower on hot with the door closed to create a steam room, then turn off the water and leave him/her in there for 15 minutes to help clear the mucous out and help him/her breath better. Sometimes it will help but many times it does not clear the problem. You really need antibiotics if it is indeed kennel cough. Are you sure it is not a heart issue causing the cough? Especially being he/she is a little older I would suspect a heart issue causing the cough and not kennel cough. You should really seek vet care somehow.
