Update
Well...first thing this morning I called the vet's office to make sure the little guy made it through the night. He did and even wagged his tail a bit for the tech upon greeting him this morning. The vet called around noon with his findings after the check up...
According to his white blood cell count he has Parvo. It should be I think he said around 3,000. Simba's (that's the pup's name by the way) count is 80. From what I could understand his bone marrow is wiped out. In fact, all his counts are extremely low on every test. Plus, he has Hookworm. He is definitely on a day to day basis at this point. He also mentioned "sudden death" that is still a possibility.
I asked his opinion on euthanizing Simba, and he said that he couldn't really make that decision for me. My vet said he'd like to give the guy a chance and keep him for 5-7 days on meds, IV antibiotics, etc. With that being said they will cover the cost if I'd pay the limit that I had stated I could afford from the beginning. He said Simba may make it he may not, but let's give him a chance. My vet said that he had a case come in not that long ago just as bad, and that dog rallied through and found a forever home and is doing wonderfully. He asked that I come in to visit the puppy, so he could see a friendly face that isn't poking and prodding at him.
I called about Simba this evening when I got home to tell them I'd come by tomorrow to visit since I will have to wear gloves and a gown I didn't want to show up unexpectedly. They said he's doing fine so far, is taking his pills fine so is v. hand friendly and they expect he'll stay that way even after he gets better.
I explained the situation to my friend and he is still going to take the fella in until we find a home. He might've already found a forever home for him.
Anyway, he's definitely not out of the woods, but seems to have a few more
folks in his corner.
