Dutch had an eppisode of hives that lasted several days after his last dose of Quest. I'm not going to try it again for fear of another reaction. What is the best spring deworming protocol for IR and EMS horses. I've looked through the files and can't find any advice.

Rebecca,
Do you mean QuestPlus was the problem? Plain Quest/moxidectin is available without praziquantel. 

ECHorsekeeping has lots of information about deworming. Look at the Guidelines:  https://ecir.groups.io/g/Horsekeeping/files/Deworming%20Guidelines%20Update.pdf

I think it was Quest Plus but it was a year ago and I'm not sure which one it was!
