Toxic blue-green algae in ponds, lakes is deadly to dogs and wildlife

It took 15 minutes for the playdate to turn deadly.

Melissa Martin and Denise Mintz’s three dogs — Abby, Izzy and Harpo — had spent Thursday evening romping in the mud and chasing their ball at a pond in Wilmington, N.C. The evening getaway was a welcome reprieve from the late-summer heat.

But unbeknown to the dogs and their owners, the relentless August sun had also made the pond a bathtub of toxins. A poisonous microscopic bacteria called blue-green algae had grown in the water, a threat Martin and Mintz did not know about until it was too late.

On their way home, Abby, a white West Highland terrier, fell first and began to seize, Martin told CNN. They rushed to a veterinary hospital, where Izzy, also a Westie, began seizing as well. Then six-year-old Harpo, a doodle mix that worked as a therapy dog for hospital patients, fell ill.

By midnight, Martin told CNN, all three dogs were dead.

“We are gutted,” Martin wrote on Facebook soon after. “I wish I could do today over. I would give anything to have one more day with them.”

Since then, another family has made headlines for the loss of its border collie, Arya, who died after swimming in a Georgia lake from what their vet suspected was blue-algae poisoning. And in Austin, in early August, three dogs died because of the same neurotoxins, their owners said, and the city closed the lake where the dogs had been swimming.

And here we go again! It’s a traumatic, excruciating death. We are heartbroken for them, and unfortunately, we know how they feel, times three.

Martin told CNN she now hopes to help prevent more dog deaths by educating pet owners about the deadly algae blooms and advocating for warning signs near ponds, lakes and canals where the toxins have taken over.

“I will not stop until I make positive change,” she told CNN. “I will not lose my dogs for nothing.”

As of Monday afternoon, a GoFundMe page had raised about $3,500 to help Martin complete her mission.

“I can promise you every penny raised will be used to raise awareness and get signs and information out,” Martin wrote on Facebook.

Dangerous algal blooms are a “major environmental problem” in all 50 states, and scientists believe they will continue to wreak havoc on U.S. waterways with the rising threat of climate change, according to the Environmental Protection Agency. Red-tide algal blooms have killed marine life on the Florida and Mississippi coasts.

Toxic algae can affect the nervous system, liver and kidneys in humans and animals, though children and dogs are most susceptible because they tend to wade in shallow areas on the edge of ponds or lakes where the blooms are concentrated, according to the North Carolina Department of Health and Human Services. It can be especially dangerous for dogs, which drink the water or ingest the blooms by licking themselves.

To thrive, algal blooms need sunlight and stagnant, nutrient-rich water, which is most common in lakes, ponds and canals but can also be present along the coasts of bays, gulfs and oceans.

When water is slow-flowing, it warms faster — allowing toxic bacteria to thrive and the algae to grow faster and thicker. Additionally, algal blooms absorb sunlight, which warms the water further.

Other issues related to climate change affect algal blooms, including salinity changes from droughts, higher levels of carbon dioxide, extreme rainfall that promotes runoff of man-made toxins and sea level rise that leads to warm shallow waters, according to the EPA.

Humans contribute to inserting more nitrogen and phosphorous into U.S. waterways, which creates the nutrient-rich environment in which algae thrives. Storm water, wastewater, fossil fuels, agricultural runoff from crops and livestock, and home fertilizer can drain into streams and soak into groundwater, according to the EPA.

Martin told local TV station WECT that they would have never taken their dogs into the water if they had known about the dangers.

“I want to see signs on every body of water like this,” Martin told the TV station. “I don’t care if it says private property or no trespassing or whatever. Put some signs up so people know.”

5 meals we haven’t fed them…instead, we watch this video and see Harpo’s perfect little sit, Abby struggling to follow the rules, and Izzy’s constant dribble waiting for her bowls. Pray for us 💔

All three of their dogs were therapy certified, Martin and Mintz told WECT, and Harpo had earned local fame in 2014 when Martin and the canine asked residents in North Carolina to “adopt” people living in senior facilities during the holidays. The “Harpo Saves Christmas” initiative brought sponsors to all 171 residents of a facility, and Martin and Harpo delivered the gifts on Christmas Eve.

In her Facebook post and interview with WECT, Martin said she had been writing a book about Harpo’s work as a therapy dog, with the goal of getting her pup on “Good Morning America” or the “Ellen” show.

“I was trying to finish this book before he got too old to do any of that,” Martin told WECT. “Now he’s already gone, so I have to do it for him and not with him.”

Their awareness campaign, Mintz told the TV station, will honor their “three pups’ legacy.”

“If we can touch anybody, if we can help anybody not have to go through what we are right now, we will have done our part,” Mintz said.
