You simply get out the two word solution: YOU'RE FIRED. And move on, giving your money to someone honest and sympathetic to your needs.
Now, that doesn't speak to the unnecessary over use of titer testing, nor the simplicity of getting a letter from a sympathetic vet to have on file saying your dog is a patient, already immunized, and won't be getting any further vaccines. I had a 99% acceptance rate for those when I wrote them. If the groomers and kennels start demanding titers, that's just more foolishness, as I'm guessing the owners of those establishments have missed the memo on DOI (duration of immunity, another useful term to look up in the search box over there in the right hand column).
