My puppy was also hypoglycemic and had coccidia when he was a pup. He almost died on us, and one vet told us he wouldn't make it through the night, but we were not about to give up on him!
We made some boiled chicken and he actually ate some of it...After a couple of days, he decided he didn't like that anymore, so we were force feeding veterinary science diet a/d...then I found a website about someone who's pup almost died from coccidia and said they fed their pup human baby food (pureed chicken), and that worked...He actually ate this stuff for quite awhile, and he wouldn't touch anything else. I was just happy to see him eating.
We made sure he had small, but very frequent meals, and all the while, we were giving him pedialyte to make sure he didn't dehydrate. If he didn't drink it on his own, we gave it to him through syringe. Also, nutrical for whenever he needed it. The important thing is to not let his blood sugar drop. Once it drops, it's harder to get him back to normal. Just prevent it by keeping him fed.
Also, we were giving him albon, but it didn't seem to even be touching the problem after only 7 days, so we continued the albon for almost 1 month, and the coccidia finally went away!
His first couple of months with us were very hard, and it almost seemed like there was no hope, but always have faith! Continue to do what you're doing. Make sure he's drinking pedialyte, and try the pureed chicken baby food...You'll be surprised, he might eat that on his own. Good luck, and keep us posted!
