Could your horse be showing signs of Cushing's Disease (PPID)?
PPID is a common condition in older horses and early testing can help identify the condition and support long term health and wellbeing.
The ACTH blood test is the main way to diagnose PPID. A blood sample is analysed for ACTH levels, with raised levels indicating the possibility of the condition.
When should you test?
ACTH levels naturally fluctuate throughout the year, especially in summer and autumn. While autumn is often the recommended time for testing, horses showing signs of PPID or health changes can be tested year round.
If you’re concerned your horse may have PPID, please get in touch on 01653 695743 for advice and support.
