I don't know what to do for my little guy.

He is only 9 weeks old, and I just got him last week. My husband is in the navy, and we're stationed in Japan. I took him to the vet, but I don't speak much Japanese. Gizmo has diareah real bad. When I took him in they drew blood and took a stool sample. His blood sugar level was about half of what it needs to be, so they gave him a shot. He also had Coccidiosis (a parasite) and the vet gave me medicine to give him once a day for 8 days. His WBC count was fine, but he is low on red blood cells. I'm afraid if he doesn't eat anything he'll get worse.

I tried baby food, canned puppy food, milk(which he usually loves), and I got nothing. All the poor little guy will do is sleep. Anything would be helpful. This is my first puppy.
