My horses' rugs always seem to slip to one side regardless of the make. I intend to buy new ones this year but reluctant to pay too much if same thing happening.
P. S. Pony's rugs don't slip and he has same make as big boys!
I had a Bucas TO rug and it was a gorgeous rug - really well made and the click and go front fastening made the rug so snug and comfortable for my horse - no gaping front BUT, the rug ALWAYS slipped to one side. Shame really, I never use it now.
I had a horse whose rugs always slipped, regardless of make. Both stable and field. I put it down to his shape - he was ID X TB but built like an old fashioned chaser. He had bony withers, was narrow across the shoulders but had wide hips and a massive muscly bum. Everything twisted round on him!
