Overview

Fera Pet Organics makes this a full spectrum gut health chew for dogs, combining probiotics, prebiotics, and postbiotics in a chicken-flavored soft chew. The 90 count jar is intended to support digestive health and anal gland function.

Postbiotics alongside probiotics and prebiotics is a more complete formula than probiotic-only chews, though the listing directs active ingredient detail to the product label rather than spelling it out here. It is positioned as a general gut support supplement rather than a treatment for a diagnosed digestive condition.

  • Full spectrum pre, pro and postbiotic formula
  • 90 chicken-flavored soft chews
  • Supports digestive health and anal gland function
  • Suited to all dog breed sizes

Who it's for

Suits dog owners looking for an everyday gut and immune support chew, especially dogs with recurring anal gland issues the product specifically targets. Dogs with acute digestive illness should see a vet rather than relying on a supplement alone.
