Skip I'm not in the least bit surprised. I think most vets misdiagnose Babesia for many other things unless they test specifically for it, which can also be difficult.

Babesia is a complex parasite/bacteria, it doesn't want to kill it's host because it wants to survive. This is why often times dogs will go through life and not show symptoms.

The symptoms you described initially can all be caused by Babesiosis, it's important we recognize these things so when we go to the vet we have a head start and possibly save time and money.

I have read recently it has been discovered the anti malaria drugs do not work as well on Babesia as thought. The parasite is elusive and likes to hide in tissues waiting for its opportunity (weakened immune system) to strike. Anthelmintics paired with combination antibiotics done intermittently seems to be the new option in treatment.

Glad to hear he's recovering Skip, if he were mine I'd make sure to Ivomec (Anthelmintic) him on a regular schedule.
