Pedigree Query

I've never seen a horse I couldn't get a needle into faster than getting a gel under its tongue. An oral gel might be handy for a novice owner but I can't see the benefit for a vet or an experienced horseman.

My farrier was telling me about this the otheer day. Said he has a draft horse client who uses it on a Belgian who just won't stand still but after having this, his head is hanging and they can do anything with him.
Seems like it could have some major potential for abuse, though, as in people trying it on themselves.
