Red Worms in Pond & Border Collie Drinking Water: Any Risk?

After cleaning a pea-soup pond, owner found tiny red worms. Border collie drinks from pond—could it get worms?

The Worms Are Bloodworms

Tiny, red, with distinct heads = midge larvae (bloodworms). Larger red worms = earthworms. Neither are parasites.

Dog Safety

• Bloodworms/earthworms: Not parasitic; no infection risk from drinking water.
• Real parasites (roundworms, giardia) live inside hosts, not free in pond water.

Pond Health Note

Pea-soup algae indicates nutrient excess. Add floating plants, improve filtration, consider barley straw. The worms are a sign of organic processing, not a problem.

Your border collie is safe—enjoy the pond together!
