Crushed Wednesday

My pup is getting no better, the meds are 3 days in, the vet called and said his bloodwork shows he is further along than he expected, I wasn't surprised. Bowie is visibly struggling more, I fear he will not make the week. He still greets, he still wags, he stil wants to play, he is completely limited by only his heart. The ride was fast and ok but my mind was elsewhere obviously.
