Dogs’ owners issue warning about deadly toxic algae

- Health & science By Katie Mettler

It took 15 minutes for the play date to turn deadly.

Melissa Martin and Denise Mintz’s three dogs — Abby, Izzy and Harpo — had spent last 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 unbeknowns­t to the dogs and their owners, the relentless sun had also made the pond a bathtub of toxins. A poisonous microscopi­c bacteria called bluegreen algae had grown in the water, a threat Ms. Martin and Ms. 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, Ms. Martin told CNN. They rushed to the veterinary hospital, where Izzy, also a Westie, began seizing as well. Sixyearold Harpo, a doodle mix who worked as a therapy dog for hospital patients, fell ill too.

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

“We are gutted,” Ms. 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 their border collie, Arya, who died from what their vet suspected was blue- algae poisoning after swimming in a Georgia lake.

And in Austin, Texas, 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. “It only took one hour from the time we left the water for Oliver to breathe his last breath,” Brittany Stanton, one of the owners, wrote of her 2- year- old golden retriever in a Facebook post.

Ms. Martin told CNN she 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 morning, a GoFundMe page had raised more than $ 3,000 to help Ms. Martin complete her mission.

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

Dangerous algal blooms are a “major environmen­tal problem” in all 50 states that scientists believe 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 algal blooms are concentrat­ed, according to the North Carolina Department of Health and Human Services. While the sight and odor of algae repels humans, it can be especially dangerous for dogs, who drink the water or ingest the blooms by licking themselves or snapping at floating algal balloons. Toxic algae can also dry up into crusts onshore, where dogs might nibble on them.

“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,” Ms. Mintz said.
