Yesterday Tonka was using his flehmen response to assess Raven's back end (she's in heat again -- let's hope it's the last of the summer) when I noticed some faded green markings right at the front of his upper lip. It turns out that Tonka is tattooed! Given that he (a) looks like a big 'ol grade horse and (b) was sold to me as a big 'ol grade horse it has never occurred to me to check. Christina is coming to trim the beasts next week, so I will solicit her help in getting a picture -- Tonka tolerates most manhandling without complaint, but he does not like oral poking and prodding.
I know nothing about the administration of horse tattoos. Purebred dogs are often marked and registered by their breeders, but vets will tattoo any old mutt for the purpose of identification. Does the same go for horses, or does the existence of a tattoo define Tonka as the member of some breed registry? And, if so, what registry? He looks like a big 'ol grade horse!
