Oh
@Huggy ! I am sorry but he needs to seriously get at least 100# off. He looks just like my Joker did when his insulin shot up to 303, Cornell marveled he was still alive, and he foundered so bad I thought Iād lose him.
Is he boarded or at home where you can monitor him?
In the U.S. we have a couple of things to put a horse on to help them lose weight. Thyro-L Is the typical go to but my lameness vet will also take the herbal route if the owner is favorable to that. I was, so he put Joker on the herbal compound Hot Hoof I.
Joker also went out to pasture wearing a muzzle that he fought for three weeks. I would have to bring him into the barn every afternoon so he could eat measured hay, drink water and eat salt. I was about to give in with the muzzle and I finally saw him eating & drinking with it.
He wore the muzzle for daily turnout seasonally. I took it off when he came in at night but I weighed his hay that I had sent out to be tested for NSC value.
The weight came off slow which was good. We fought IR for three years. He has been in remission since 2015, hasnāt worn a muzzle since 2015, and self regulates his grass & hay intake like he should.
His hooves are shot from the seroisn of the founder (he rotated almost down theu his sole on the LF), but I have a therapeutic farrier who does a bang-up job keeping him sound as is possible.
I hope you can get the weight off your horse before his Insulin goes way out of control.
