Thanks guys, this is a friends horse..he wasnt like this when she had first purchased him, but after being boarded with other horses that are rarely dewormed, its no wonder why he became so full, the vet is scheduled to come out tomorrow, just looking to see what others thought as well
I do know the guy she got him from only used ivermectin twice a year to deworm,(and fed off the deep sandy dirt in a roundpen-including when it was muddy) so my guess there is a great chance he had a small case when she got him in october..since then he was dewormed, and sand-cleared, but is in a pasture with 3 other horses that look..puffy..like he does
