If you own a senior horse, be aware of the early warning signs of PPID (pituitary pars intermedia dysfunction), formerly known as equine Cushing’s disease. They include a change in body conformation; fat deposits on the neck, tailhead, or above the eye; and abnormal hair growth in small regions, such as around the chest. For more information, including a visual graph of both early and advanced signs, go to idppid.com.
