Has anyone heard of something called "Corn Cob Disease"? I haven't been able to find anything on it. I am an Equine Massage Therapist, and was presented with this question! The trainer just said that the vet mentioned this disease, and that maybe it has something to do with the sacrum. He didn't have any other details. The horse is a 3 year old Standardbred trotter. I appreciate any info you can provide - we are stumped! Hopefully the trainer will get more info from the vet...this is just more for my own curiosity at this point. Thank you!
