Many ponds and lakes are home to an unseen threat. Cyanobacteria, sometimes known as blue-green algae, is a kind of bacteria that flourishes in warm water. It emits a harmful toxin which is poisonous —and perhaps fatal—to both humans and dogs. This is important information for all pet owners to know, but it’s especially crucial for people who take their pups swimming in freshwater. Read on to learn more about this hazardous poison from a local Washington Heights, TX veterinarian.

What Is a Blue-Green Algae Bloom?

This algae is especially harmful because it produces a particular type of toxin. Blooms can occur when the average water temperature exceeds 75 degrees Fahrenheit, when many bodies of water are most nutrient-rich. That means the hottest months—particularly during and immediately following the dog days of summer—are extremely perilous. It’s most commonly found in shallower lakes and ponds. When the conditions are right, blooms can expand rapidly.

How Dangerous Are Blue-Green Algae?

Blue-green algae is harmful to both humans and pets. Diarrhea, nausea, vomiting, skin rashes, eye and throat irritation, and respiratory distress are all possible reactions to exposure. It may also result in severe brain issues and/or liver failure. Large concentrations of algae can be lethal. There is no cure, unfortunately.

Dogs and animals are especially vulnerable because they don’t know any better than to drink the water and can consume a significant amount before you can stop them.

What Are The Early Warnings of Exposure in Dogs?

It is always crucial to keep a close eye on your furry family member and pay attention for signals of trouble. In this instance, you should look for panting, respiratory issues, vomiting, diarrhea, dizziness/disorientation, and excessive drooling. Another red flag is the occurrence of seizures. If you observe any of these warning signs in your canine companion, call your veterinarian or an urgent care pet facility right away.

As previously stated, no antidote exists. However, effective supportive care can make a significant difference. For further information, ask your veterinarian.

How Do Dogs Consume Or Ingest Blue-Green Algae?

Drinking contaminated water is perhaps the most prevalent method for dogs to become ill, but it is not the only one. Toxins can also be ingested by humans and pets via their skin or by inhaling water droplets or mist. This means that you and Fido can become polluted while tubing, water skiing, swimming, floating, or boating.

Dogs, of course, enjoy splashing around. Pets can become ill from just playing in water. They may also later lick the cyanobacteria off their fur.

How Can I Tell If a Lake Is Safe For Fido?

If you smell an unpleasant swamp odor or detect the unmistakable green scum, you should assume the lake is dangerous. However, as previously noted, you may not see the bloom. Look for posted signs; many local governments may publish notices when blooms are confirmed.

You may also view the HAB (Harmful Algae Blooms) map, which can be accessed here. This website provides updates on blue-green algae blooms in each state.

What Should I Do If My Pet Comes in Contact With Cyanobacteria?

Your first step should be to properly clean Fido. We strongly suggest you consult your veterinarian as well. You may find yourself in a waiting game as you wait for potential signals to appear.

It’s worth noting that, regardless of whether Fido was swimming in a pool, lake, or beach, we always recommend cleaning him off afterwards. Sand, salt, and/or chemicals always need to be removed from his fur and skin.

How Long Do Blue Green Algae Blooms Last?

Individual blooms last only a week or two. However, when conditions are favorable, they may be promptly replaced by another. That means lakes might be poisoned for weeks or even months. This often occurs between mid-to-late summer and early fall.

Will Boiling Water Get Rid Of Blue-Green Algae?

No. This is vital to remember if you enjoy camping with Fido and frequently boil water from lakes or ponds to drink or cook with. Boiling may kill live bacteria and microorganisms, but it does not remove cyanobacterial toxins.

What More Should I Do To Keep Fido Safe At The Lake?

Cyanobacteria aren’t the only potential hazard hiding in lakes. Swimming might be a lot of fun for Fido, but it can also be harmful. Some canines are simply not suited for it. If your dog is brachycephalic or has mobility limitations, he may benefit from swimming around in a kiddie pool. Very small canines are also unsafe in the water, since they can drown in even shallow water. If you’re not sure whether swimming is appropriate for your dog, see your veterinarian.

If Fido does not know how to swim, take time to teach him. Never just put a puppy in the water and hope for the best. Encourage him while he learns by giving him praise and comments.

However, it’s also critical to keep a watch on Fido while he’s in the water. Never leave your furry friend alone near water. You’ll want to avoid taking him anywhere with blue-green algae blooms, as well as places with steep drops, large wakes, and strong currents. Red tides are also a risk for anybody visiting the beach this summer.

Your dog should know basic obedience instructions like Sit, Stay, and Come. This is critical because it keeps your pet from reaching a potentially unsafe area. If you’re taking your dog to the pool, start by teaching him where the stairs are.

Last but not least, do not allow your canine companion to drink water from lakes, ponds, or puddles. In addition to the cyanobacteria risk, Fido may contract parasites, such as Giardia. Ask your vet for more information. 

Is It Safe to Swim In Blue-Green Algae?

Certainly not. It doesn’t matter how pretty a lake is, or if it has historically been safe until now. Part of the risk here is that blooms may be present but undetectable. Even if a lake or pond looks safe, conduct research and consult with local authorities. Stick to areas that have been cleared and are open for swimming.

How Do I Know If Blue-Green Algae Are Present?

Blue-green algal blooms are often visible and odorous. Cyanobacteria is referred to as blue-green algae for good reason. The blossoms frequently resemble pea soup or green paint. They also frequently emit a foul-smelling, marshy stench.

However, one cannot judge based solely on appearance. Smaller blooms may not be visible with the naked eye. As always, err on the side of caution here, and go somewhere you know is safe. 

Conclusion: Blue-green algae, or cyanobacteria, is a harmful algae that blooms in many lakes and ponds during the summer. It is particularly harmful to pets and livestock. Exposure can be fatal for our canine companions. Pet owners must understand the dangers and how to identify and prevent blooms.
