๐ข If the lake looks like green paint, keep your dog out ๐ถ
Blue-green algae, also called cyanobacteria, can appear in lakes, ponds, and slow-moving water across the U.S., especially during warm weather. It may look like green paint, foam, pea soup, or floating mats.
Dogs are at risk because they swim, drink, and lick water from their fur. Exposure can become serious fast. Warning signs may include vomiting, diarrhea, weakness, drooling, tremors, breathing trouble, or collapse.
Do not rely only on smell. Some toxic blooms do not smell terrible. Check local water advisories before letting your dog swim.
If your dog enters suspicious water, rinse with clean water and call your vet immediately.

Tip: Avoid water with bright green scum, foam, or warning signs posted nearby.
