This morning i woke up and let the dogs out like normal. I let them out did a couple of things then went to bring them in so they can eat. Rhun is always the first one in everyday, once he is done his business he always finds a spot to relax by the front door. Well today he was by the back fence laying in the grass and he didn't want to get up and come in side. When i did get him in he started doing this hacking cough like he is trying to hack up a fur ball like a cat but all that ends up happening is a cough comes out. Usually when they hear the click of the container of food open they come running but rhun just stayed layed down in the living room. Went and got him but he still wouldn't eat his food. Called the Vet and got a appointment but it isn't for another couple hours! He also has a dry hot nose, shivering, heavy breathing, and can't keep his eyes open though is is trying to fight it. I am worried sick and the waiting is making it worse, anybody have any ideas?
