The horse may lie down a lot and be depressed
Not stepping out properly – goes with a shuffling gait, worse on corners or when asked to go downhill

History of laminitis or founder commonly induced by grass
Puffiness in the hollows above the eyes
Sheath swelling in geldings
Advanced symptoms may include increased thirst and urination
Loss of body condition and muscle wasting
