Should I still deworm him to ensure that he will not bring any over to the new grazing? (On the new grazing he will be grazing by himself in large paddocks with only a neighbors horse over the fence in one paddock)
I have only had him since Nov 2010 and the entire time he has been grazing solo in large paddocks (roughly 5 acres in one particular paddock) he's only ever grazed with my neighbors horse for 3 days in the time that I have owned him and since been dewormed.
I have mixed thoughts on the situation, I've been told to do a FEWC but then I have also had a vet say they are not very accurate and that you could have a negative sample and yet still have worms. Then people saying I should deworm him prior to really give the worms the boot but then others saying you'll be building up a resistance to the dewormer drug!!
