Hi Misfits:
I found the same information after hours of research on the internet. Thanks for confirming my suspicions. I have an appointment with my vet for an EKG. Take care.
Hi Pugdaddy....A Senior dog Coughing at night or early morning (After laying down) is indicative of CHF (Congestive heart failure)......Don't panic! This condition is very common and can be controlled for years w/medications....An EKG is the place to start.....If your Vet is not able to provide one, then you need to see a Canine Cardioligist....Let us know what the Vet says & good luck.....Karla
