Normally bouncy and full of life, he is now lathargic and lazy, can't be bothered even walking from stable to field.
Normally fed one haynet at night, gets a small bucket of chaff, nuts and balancer. Haven't changed any of that except the brand of balancer.
The weather has been very hot, he wears a Snuggy Hood rug during the day when he's in the field cos he has sweet itch.
He is five years old.
He has the odd cough now and then but not a chesty one.
Any thoughts?
