The problem with giving doxy for every engorged tick incident is that it sounds like he would be on it all the time. Have you started him on tick preventative? What one?
The lyme's vaccine itself can cause a high titer, so the dog tests positive for the disease but doesn't really have it. That may not have happened here, but is possible. I would be concerned about the polyurea/polydipsia. Whatever is causing it, lyme's or not, it needs to be treated immediately (today). Something isn't right. It could be lyme's nephritis or it could be stones (was an xray done) or an infection or or or... Was a culture done? Xray? Ultraound? Kidneys problems are not uncommon in older Yorkies, but even if it is just old age, there are things that can be attempted. If he is drinking a lot, diuresis may help. A kidney diet may also be tried. Time to switch vets.
