We have a very sick pitbull mix here at home that I have to keep checking on his cuz he collapsed last night and he is due to go to the Vet anytime now. He's breathing heavy and was throwing up last night. He is on antibiotics but they don't seem to be doing anything for him. He is very listless and is just laying in one spot breathing really heavy even though the AC is set to 75 degrees in here. He was an award winning show dog in his day. I'm just hoping they can help him. This is what he looks like right now.
