I have not needed to use Pergolide for Rory. For over 6 years his Cushings symptoms have been controlled with the spice Chastetree Berry plus all the other supplements I use for most horses. I do not think of it as a cure, just management of his symptoms.
The only remaining sign of Cushings is a slight curl to his winter coat a month or so before it starts to shed.
Hi Pauline, thanks for the information. Since my horse is in his 23rd year, I think I will have him tested, and I know the vets recommend Pergolide, but I've heard good and bad things about it. I like to know my options.
