From Montana FWP Facebook:
Attention bird hunters!
Before your dog gets into the water or drinks out of a pond or lake, check for harmful algal blooms (HABs), which may appear like pea soup, spilled paint, grass clippings, or water that is discolored.
Harmful algae, or cyanobacteria, can cause illness and death in dogs. If your dog gets into water you suspect is a HAB, rinse them off with clean water right away and don’t let them lick their fur.
Contact a veterinarian immediately if your pet seems sick. Learn more about HABs, what to look for, and active caution advisories based on citizen reports at hab.mt.gov
