I know that rabies requires exposure to an infected animal, but who really knows what these poor animals were put through and other animals that have the poor misfortune of belonging to these people probably aren't cared for/vaccinated either.People used to never think that rabies could infect horses/cows/etc either.I know back in 1988 when I was blessed to be able to own my first horse I request rabies vac for him.The vet was actually suprised said it wasn't necessary,etc but would vaccinate if I really wanted him too.We did and as the years went by, my large animal vets actually began recommending the vaccines for large animals.I think it was about 5 years ago we had a confirmed rabies case in a horse a few counties away.The animal of course was put down,2 nearby pasture mates had to be quarantined for a very long period and a few of their dogs put down due to no proof of vaccination.The owner also had to be treated.It was never determined exactly how the horse was infected but speculation was that it may have been in contact with rabid racoon,fox or feral cat.Since the chin is going to be necropsied I'm sure they'll check for it, but it never hurts to be sure.
