Do you offer a feed that would be good for a horse with Polysaccharide Storage Myopathy (PSSM)?By NS KNG Admin / March 25, 2024 Yes, we have several products, including supplements and feeds, depending on the horse’s needs. In general, our Sentinel Performance LS and Sentinel Senior extruded feed products have both worked well for horses with PSSM. We also have Sentinel Care Carb Guard and other Sentinel Care supplements that may be more appropriate, depending on the individual horse. (Jeanne van der Veen)
