answered 11/16/2010 My Dog Keeps Gagging/coughing And Spitting Phlegm, What Should I Do? ANY time your dog is gagging and spitting up ... GET THEM TO THE VET ASAP..... That is the first sign of Congestive Heart Failure!
answered question 11/16/2010 Chocolate Lab Is Coughing Really Bad. It Sounds Like The Croup And She's Spitting Up Lots Of Phlegm (sometimes Looks Bloody). She's Still Wagging Tail, Walking Around & Doesn't Seem To Be In Pain. We Know Its Not Heart Worms. What Could It Be? More than likely, it sounds like Congestive Heart Failure. Get your dog to the vet NOW!
