I wormed my horse and her companion pony at weekend and was alarmed to see a few live red worms in the horses droppings and a few dead white worms in pony's. I wormed them with equimax. I had a worm count done on the horse in the spring which came back at zero, so she was only wormed once in the summer with equest. The companion pony is a new addition (so not sure what his worm count would be), but they are in separate paddocks and I poo pick the fields daily. Am really shocked that my horse obvioulsly has a worm problem!! Can anyone advise when it would be safe to worm her again, and what with (was thinking of equest)?? Thanks.
