ADVERTISEMENT Pituitary pars intermedia dysfunction (PPID, or equine Cushing’s disease) has been a challenge for horse owners and veterinarians for years. As researchers learn more information about it, the clinical signs of PPID are becoming more recognizable in horses. However, there are still several other misconceptions or myths about the disease. Here, Steve Grubbs, DVM, PhD, Dipl. ACVIM, equine technical manager for Boehringer Ingelheim Vetmedica, Inc., dispels some of the most common misconceptions. Misconception: PPID is only a condition of the geriatric horse. Yes, PPID is common in senior horses. But, that it only imacts older animals “is probably one of the most common myths about PPID,” Grubbs says. “We have been tracking epidemiological information on horses diagnosed with PPID, and have found that PPID affects horses of all breeds, and all ages, even as young as 5 years old.”
