PET HEALTH CORNER: Dangers of stagnant water

During the warm weather, us pet owners love getting outside with our pets! But with the beautiful temperature comes some dangers. Stagnant water, is one of them!

Blue-green algae, specifically, can endanger the life of your pet. This algae forms on or near bodies of water during warm weather months. It can be found in ponds and lakes, fresh water, backyard fountains, or even on rocks.

Your dog can be affected if they drink from or swim in contaminated sources.

Signs of blue-green algae toxicity in stagnant water include:

  • Panting
  • Excessive drooling
  • Respiratory failure
  • Diarrhea
  • Disorientation
  • Vomiting
  • Liver failure
  • Death

Don’t allow your pets to drink from stagnant ponds, lakes or other bodies of water that have bluish-green scum on the surface or around the edges.

The cells of the blue-green algae can also latch onto your pet’s fur, which can be invested when the animal cleans itself. This is why it’s important to wash your dog after they have been in contact with any bodies of water..
