Tedd,
Rheumatologist I had told me that Lyme does NOT resurface once killed off, but in humans at least, the DAMAGE done by the lyme can flare and cause many issues years later, as it would appear to be a relapse.
I don't know about dogs...
Given the lack of good data on Lyme management in humans, wonder how well it's been studied longer term in animals?
Seems that dogs give 100% and then, have shorter lives then we'd want...perhaps they give so much love because they have less time to share?
Humans could do well to mimic that if so!
