My horse started drooling about a week ago. The next day while eating his grain he was chewing funny. Over the next couple of days he would eat his grain sort of but kind of seemed like his lips were numb and had a hard time getting it. The drooling continued but seemed to lessen. Two nights ago wasn't intested in his grain at all. Last night he was just not right, wouldn't eat and now you could see bloody drool. I tried to look at his mouth and teeth, but I'm no vet, everything seems a bit swollen. This whole week he has also been in the pasture so I figure he is eating. The vet came out this morning and he thinks it is blister beetles causing his troubles. His tounge looks like a blistered rotting piece of meat. Any ideas in adition to what the vet has said would be greatly appreciated.

This article was very informative and timly. I would like to see a picture or two of the beetle though.
