Is Pyramid Lake safe for dogs?
Lower predicted bloom risk
This lake has a lower predicted bloom risk, but predictions are not a guarantee and toxins can appear anytime. Always look for scums before letting your dog in the water.
Predicted risk isn’t the same as today’s water. Blooms come and go — always look for green scums before letting your dog near the water, and check your state’s current advisories in season.

What blue-green algae means for your dog
Blue-green algae (cyanobacteria) can produce toxins that are rapidly fatal to dogs, who are exposed by swimming in or drinking affected water and by licking it off their fur. Dogs are affected more often than other pets because they wade, swim, and drink from lakes and ponds.
A “lower risk” prediction lowers the odds but does not rule out toxins or a localized scum in the cove where your dog actually swims. Predictions describe a lake’s tendency, not today’s water. Treat this page as a first check, not the final word.
