PPID did not seem to exist in the past. Older horses, those aged 15 and over, would develop age-related issues that would worsen with time. Occasionally, a fortunate senior horse might have the kind of vet willing to consider what was previously known as Cushing’s disease. Thankfully, the past two decades have brought about a positive shift. Scientific knowledge is more widely available, revealing that what was once merely considered to be a range of age-related issues can now often be diagnosed as characteristics of PPID; the current term for what is now recognised as a stand alone challenging condition. PPID-affected horses remain under the radar less frequently, because we ourselves as horse owners are more likely to raise the alarm if we think our horse has PPID.
