Harmful algal blooms (HABs) can pose serious health risks to our beloved animals and humans.
Be on the lookout for green or blue-green algae in the water – and steer clear of it. While algae naturally occur in lakes and ponds, excessive growth of certain types can result in harmful algal blooms (HABs). Just as the name suggests, HABs are harmful, even toxic, to animals and animals if ingested, inhaled, or if physically touching the skin.
Harmful effects to dogs: Exposure to HABs can cause dogs to have mild to serious health effects including rashes, lethargy, diarrhea, vomiting, dizziness, and even seizures.
High-risk areas: Exercise caution near still waters, such as ponds or slow-moving streams, where these blooms are most likely to occur. Dogs are at greater risk for exposure in all water bodies because they tend to drink surface water, groom their fur afterwards, and are attracted to algal scum odors.
What You Can Do
☑ Leash dogs near shorelines
🏊Avoid allowing dogs to swim in areas with visible algae blooms.
🐕Remove dogs immediately from suspicious looking waters
☑ Never allow pets to drink suspicious looking water
💦Rinse off pets with fresh water immediately after swimming, even in areas not affected by blooms.
🐕Don’t allow dogs to lick their fur after swimming
🏊Wash your hands and arms thoroughly with soap and warm water after pet cleaning.
🚫Follow all posted warnings, including signs indicating unsafe water conditions.
💦Monitor dogs for symptoms after any possible exposure to HABs.
If a pet has been exposed to a HAB and is exhibiting symptoms, seek immediate veterinary care or call a poison control hotline.
