Horse Veterinary Questions? Ask an Equine Vet.
Hi, i`m Richard, a Veterinarian from the UK. Hopefully I can help today.
Is there any discharge from the mass?
I suspect this is an abscess and I agree he may have caught himself on a sharp object. If you can express any discharge from the mass then squeezing it gently to do so is absolutely fine. Bathing the area with a salt water solution (~1 tablespoon of salt to 1 pint of water) has very good antibiotic properties.
I would recommend having your vet check nothing else is going on with the wound and it would be wise to keep going with the antibiotic treatment for at least 5 days. Your vet will be able to recommend a more suitable antibiotic than straight penicillin, whihc has a high level of antibiotic resistance at present.
You are very welcome.
