Swimming is a great way for dogs to cool off, but it can come with serious risks.
Blue-green algae (cyanobacteria) can be present in lakes, ponds, and slow-moving water, especially during hot weather. It often looks like green paint or streaks on the surface. Exposure can be life-threatening, even with small amounts ingested.
If your dog has been swimming and shows signs such as vomiting, weakness, drooling, tremors, or difficulty walking, seek veterinary care immediately.
When in doubt, keep your dog out of questionable water, bring fresh drinking water, and supervise closely.
