I knew I'd seen a better page on tick life cycles somewhere! A bit of
digging with google found the good old WHO page

I've seen domestic dogs absolutely covered in immature ticks and it's
really unpleasant for them, sometimes they can provoke an immune
system reaction which will make them very ill. I took anti tick
treatments out to zanzibar for my friend's dogs last trip, I'm sure
they appreciated it! The humans in contact seemed to be ok though.
Viral infections rely on certain host species being carriers and I'm
guessing zanzibar goats and dogs are free of the sort of viruses which
affect humans.
Fascinating subject parasites, I can't get enough of them!
