Why does my dog smell fishy?

A foul, fish smell emanating from a dog may indicate backed up anal glands. Discharge from anal glands or sacs is normal when a dog empties its bowels.

To another dog, the discharge signals status, either physical condition or sex. Improperly drained anal glands cause discomfort and pressure. Scooting around on the floor is an attempt to alleviate the condition. Dogs also lick and bite their hind parts. A trip to the vet is in order, but the process is straightforward: manual squeezing. Fiber-rich meals prevent impacted anal glands because stools with strong, healthy texture apply pressure on the sacs, which promotes even emptying.
