All of the vets I contacted through the Resources link so far have shown no inclination to want my money, None have contacted me with even a slightest bit of interest. It is possible they are all overworked, can't handle another dog, but at least a response saying so would be appreciated. Is there a link that gives a DIY procedure that gives information on where to start? I prefer a link that leads to a paid resource because the link provided is far more likely to give me clues on where to start, whom to contact, etc. It is not necessary for the contact to be a veterinarian (although that would be preferred) since I have quite an extensive medical background, so even though I am doing investigation for a dog, the conclusions I have drawn have turned out to be correct most of the time. Those that didn't work led to no harm.
Many of the more alternative solutions that I have received through my own deep dives I have tried on myself and after adjusting for dose, and most, if not all, showed improvements, some marked improvements (such as no more spells of vertigo) and others just so-so, but no adverse effects.
