My vet told me yesterday my shetland needs to loose some weight 
At the moment he is in a field with another shetland and 2 ponies.
Vet advises I bring him in to the stable during the day and feed him just a flake of hay which would be fine but im on a livery yard which only supplies haylage and were not allowed to buy in our own hay.
The haylage is too rich for him and ive been told if he doesn't loose weight he is liable to get lami in the spring.
Anyone here ever tried a muzzle to stop a horse eating 2 much ?
I was thinking maybe try that and bring him in for a few hours everyday and give him a bit of straw and chaff?
Any ideas anyone?
