Why Does My Dog Smell Like Fish?

A fishy smell almost always means impacted or infected anal glands. The glands release a strong, fishy secretion when they are full, leaking, or infected.

When does it become a concern?

Any fish smell from the rear end warrants attention. If your dog is scooting, licking their rear, or the smell is very strong, see a vet soon.

Home Treatment

  • Do not attempt home expression unless trained
  • Keep the area clean with gentle wipes
  • Monitor for scooting or excessive licking

See a vet if:

Any fishy smell from the rear end, scooting, or visible swelling near the tail base

Frequently Asked Questions

Why does my dog smell like fish?
The most common cause is anal glands that need expressing. When full or infected, they release a strong fishy odor. A vet or groomer can safely express them.
Can I express my dog's anal glands at home?
External expression is possible but not recommended without training. Internal expression by a vet is more thorough and safer for infected glands.
How often do dogs need their anal glands expressed?
Most dogs express them naturally when they defecate. Dogs with soft stools, obesity, or a history of impaction may need professional expression every 4 to 8 weeks.
Is a fishy smell from my dog an emergency?
Not an emergency, but it needs attention within a few days. If the area looks swollen or your dog is in pain, same-day vet care is warranted.
