Beware
During the hottest months of the year, we need to be aware of the possibility of blue-green algae in lakes, ponds and streams. Blue-green algae can be toxic and dogs who love water are particularly at risk. If your dog does go into water with heavy algae growth, hose it off right away, before it has a chance to lick itself clean. Removing the algae before the dog can ingest any of it can prevent sickness. The primary signs of dogs ingesting toxic blue-green algae is gastrointestinal upset. This can be followed by liver injury. In addition, the algae may release toxins that lead to respiratory paralysis and seizures. If you believe your dog has been exposed to blue-green algae, immediate treatment of symptoms is necessary. Horses and other livestock are also susceptible to blue-green algae toxicity.
