So I called the clinic and Dr. Suzy agreed to come out and draw their Coggins, give the shots and check their teeth.
The Coggins test is for equine infectious anemia, a highly contagious disease that so far can't be innoculated against and isn't treatable. Travel between states, and sometimes intrastate, usually require a negative Coggins.
We also innoculate for rabies, tetanus and equine rhinopneumonitis due to types 1 and 4 viruses, and equine influenza due to type A2 viruses (commonly called the 4-in-1 vaccine).
The boys are good about being poked with needles multiple times. Not so good with step 2 of our morning tête-à-tête: an examination of their teeth to check for 'points', sharp edges, broken teeth, misalignments, etc.
Dr Suzy pronounced both of them in reasonably good shape but suggested filing down a few rough edges, top rear (on both horses). I suggested, in the interest of safety for all concerned that the vet give them a little Ace (acepromazine) to take the edge off.
So the boys went to their happy place while Dr. Suzy afixed the speculum, a contraption to hold the mouth open.
And why it's called 'floating', I'm not sure; but here's a nice article about equine dentistry and why it's important.
Here's a typical tool kit:
Bob went first. When the vet turned it on, it sounded a lot like a powered screwdriver, not something Czar, in the stall across the aisle, found especially soothing. He actually went eyes-on-stalks and threatened to climb out the 2x2 ft stall window.
But the old Bobster, Mr Cool Dude himself, took it like a man.
When it was over, Czar was muttering, "Ish good schtuff, Ma."
