From a vet. If pennicillin gets directly into a horse's bloodstream, even a small amount will send them into anyphalactic shock and kill them without IMMEDIATE vetetrinary intervention. Do not attempt to give pennicillin yourself.
A horse should be given penicillin when a veterinarian determines the horse has a bacterial infection that will respond to the penicillin.
No, penicillin should never ever be given orally.
Fuuck no, you cuunt.
The horse would have a reaction to the Penicillin almost immediately. It is best to get away from a horse that has been wrongly injected with Penicillin as the horses brain will be affected and it will flip over backwards. There is no antidote for this, but you should call a equine veterinarian immediately.
Yes
i don't recommend it.
Penicillin is not always the best drug to give to a horse, you should consult with your equine veterinarian to get an exact idea of what medicine should be used for the ear infection.
Not very well
Penicillin needs to be injected intramuscular so the breast works really good or divide the dose into two and do one shot in each leg up in the muscle
You should not give a horse oral Penicillin. Oral Penicillin can seriously disrupt normal microorganisms in the digestive tract which can cause diarrhea and abdominal pain (colic). For an abscessed tooth you may need to give Injectable Penicillin, but never oral. It would be best to contact a equine veterinarian and possibly an equine dentist, as the tooth may need to be removed.
This depends on the horse and how bad the infection is. Typically it is best not to miss a day to avoid the bacteria getting the chance to overpower the penicillin. You should consult with a equine veterinarian about exact procedures regarding missed injections.
Subcutaneously means uinder the skin.
