What are the symptoms of heartworm infestation? My dog has been coughing quite a bit and I was told that it is a sign of heart worms. If she has them, can she be treated or should I have her put to sleep? I really don't want to do something like that, but I would not want her to suffer, either.
Coughing, lethargy, exercise intolerance, weight loss etc.. are all signs of heartworm dz. A simple test at the vet can help with a diagnosis. vetcare
