If I remember correctly, this is what my "rescue" dog Hoss had when I got him. He was very, very sick when i got him. He was up for adopt. threw petfinder, and the foster home he was at was terrible. I knew the minute I walked threw her door, that all of the animals there were not properly taken care of. Hoss was 4 wks(she said 7 wks, just small and had a cold) when I took him home. I thought he was going to die on me that first night.(I got back to late to take him to the vets, and just did the wait til morning game) He had servre runs, vomiting, fever, lethargic, bloated. I think he had everything imagainble wrong with him. Upper resp. infect, pneomonia, and giardia. For the life of me I can't remember the names of his meds, but was on antibs. until 3 months, and the vet finally thought he was healthy enough to start his vacc at age 1..(All along they didn't think he would make it) I didn't give up on my poor little guy. Now he is three and is over 80 lbs and a big moose.. By the way, the "foster mom" was put out of business and had charges pressed(My vet did all the paper work to help get her) and the adopt. place is no longer on petfinder!!
