    I have a 800 lb horse that has been limping from a stone briuse for a couple of weeks. My husband cut an opening in the hoof so the infection could drain out and then we applied some onitment that draws out the fluid and we then wrap it with duck tape and change it daily. He is still limping and we thought about giving him some penicillin to help with the infection, but I don't know how much to give. I've experianced a stone briuse on my quarter horse mare and she was well within a week. Anyone have any advice?

    Talk to your vet.

    You really don't want to be willy-nilly giving antibiotics.

    A stone bruise should not be cut out - it should be kept try and allowed to heal. Now you have an open wound to deal with.

    if it was an abcess, and not a bruise, cutting it out may be premature and you've just caused it to wall off and abcess again.

    That said, how much pen you give depends entirely on what type of pen it is. Call you vet ;)

    Also, if it IS an abscess, rather than a bruise ( sounds like, since bruises generally either resolve or turn into abscesses and this has been going on for a while)and the horse is still lame after allowing it to drain, there is a possibility infection has spread into the deeper structures of the foot. That is an emergency that requires some intensive care. She should be checked by a vet and may need hoof x-rays.

    Penicillin is not the best choice generally for horses as intra-muscular injection can cause lots of pain and swelling, and the horse can have a reaction ( sometimes fatal) if it is inadvertantly injected into a blood vessel.

    My 2 year old filly just cut herself on the knee today. After the vet stitched it, she prescribed 25ccs of Penicillin twice daily for a total dail dosage of 50ccs.

    Having witnessed a pen reaction in one of my own personal horses, it will be a cold summer day in TX before I ever give one again.

    I agree that wasn't the smartest choice but mistake done now to heal it! Look on your bottle of Pen. to see what kind if it's the reg. old Pen you can give 3cc per 100 lbs. 2x a day. The long acting I believe it says on the bottle IV only n 2cc per 100. Lots of different types and it will tell ya not too put more then 10cc in one injection site u can go up to 15cc in one shot. Check the bottle for instruction. :wink:

    You STILL don't want to just give pen without a vet's involvement. It may be totally the wrong thing to give in this situation.

    Please check with a vet, particularly since you're on the internet asking ;)

    You should never give long-acting Penicillin to horses. It does not achieve adequate blood concentrations to treat most infections in horses as it has a timed release carrier. Unless you are specifically instructed to use it by a vet, it can result in worsening infection and the selection for bacterial resistance.

    A shot of long-acting pen is often given to vets after a horse comes out of surgery as a infection-prevention of sorts.
