I have a 2 part question…
30 days ago I reacquired an old horse of mine (Totally a sentimental decision on my part, but in my defense he was and still is awesome). He’s a 16 year old quarter horse who has not had vet care in at least 3 years. The vaccinations and farrier care I’ve got handled, but I used a ivermectin dewormer 30 days ago and he has been showing several symptoms of having threadworms. So I don’t know if I should do a second dose of ivermectin or move on to a Fenbendazole dewormer?
Secondly:
My plan was to deworm monthly for about 3 months because he hasn’t been wormed in so long and then move to a bi-monthly schedule as per my previous experience. However, I’m at a new barn with a new vet and the barn owner recommends a monthly deworming schedule. My old barn (I was there for 4 years) dewormed everyone bi-monthly and then recently moved to collecting and counting fecal egg counts prior to deworming. Plus all the deworming schedules I can find online are bi-monthly. Is there a reason to deworm monthly? We live in South Louisiana and there is about 9 horses on 10 acres at this barn. Any thoughts would be greatly appreciated.
