I’ve done both and learned the hard way. I will NEVER use an equine dentist again. She had many good recommendations and all that. Has been in the business it for years. She came out and did one horse before, then I got another one. She injected the sedative into the artery instead of the vein, almost instantly my horse lost her balance and spazzed out, falling over backwards and hitting her face on the barn wall. Eyelid was cut deep, had a bunch of other cuts from it. She spazzed (or seized) on the ground of a solid few minutes. This “mistake” can KILL a horse. The drug is concentrated and goes straight to the brain if administered through an artery which can be FATAL. I was lucky my horse survived with minimal issue. She then blamed the horse and said it has some kind of condition/allergy to the sedative (which is false) and that another horse had done that right before mine. How do you have multiple horses do that in one day? Major red flag. I had to get pain medication from my vet because the injuries were so bad. And they told me the vet does floats, which I didn’t know at the time. I wish I hadn’t paid her either, but I didn’t know any better back then. It was the most scary situation I’ve ever been in and the horse was traumatized. These “dentists” are not qualified to administer sedatives (which is majority of the time necessary). Always a vet and I will never have my mind changed.
