Happy is always panting. Always always always. Except for when she's sleeping. What's the deal? Is she hot, in pain, old dog thing...? Could it be because of the heartworms? My vet said her heart SOUNDS good but I'm sure there's damage somewhere. She still has wormies swimming around in there and who knows how long she was infected with them before beginning treatment. It gets annoying having her always breathing her hot breath on me lol but I also don't want to be neglecting any issues that could be causing it.
