3 dogs die from toxic algae poisoning within hours of playing in North Carolina pond

Two dog owners in North Carolina are speaking out after their three beloved pups died following what initially appeared to be an innocent swim in a pond, CNN reports. 

Last Thursday, Melissa Martin and Denise Mintz took their three dogs, Abby, Izzy and Harpo, out on a playdate in Wilmington. Fifteen minutes after leaving the pond, however, Abby, a West Highland white terrier, experienced a seizure.

The owners rushed the three dogs to a veterinary hospital, where Izzy, another Westie, and Harpo, a 6-year-old "doodle" mix therapy dog, also began to have seizures. Tragically, all three pets died by midnight Friday, Martin said.  

A veterinarian later told the two owners that the dogs had been poisoned by blue-green algae present in the pond. 

"We are gutted," Martin wrote in a now-viral Facebook post. "I wish I could do today over. I would give anything to have one more day with them. Harpo and I had work to do, but now we will carry on his memory and we will make sure every standing body of water has a warning sign." 

In an interview with CNN, Martin said that she did not initially see the algae or any signs warning of the toxic substance. The veterinarian subsequently told her and Mintz that what the two originally thought may have been debris from flowers was actually cyanobacteria, Martin said.

Cavalier King Charles Spaniel

"The Cavalier King Charles Spaniel is a wonderful family pet; a gentle, calm dog, who is happy to be combed and brushed," says Dr. Emmett. "This breed is, however, less enthusiastic about games, such as tug of war, and rough-and-tumble play. King Charles Spaniels are a good match for a more urban lifestyle and a sensitive child." What does that wagging tail mean?

Golden Retriever

"The Golden Retriever is one of the most well-known dogs because of their gentle, caring temperaments.

Goldens are very bright and easy to train. They're also stoic when it comes to kids. "While they may not like it, Golden Retrievers tend to be apathetic to young kids pulling on their ears or tugging at their tails. This makes them one of the best family dogs you can find," he adds.

Labrador Retriever

"What started out as a fun night for them has ended in the biggest loss of our lives," Martin wrote of her pets. "We need your prayers. Not sure we’re strong enough to get through this without them."

Blue-green algae frequently grow in fresh bodies of water, including lakes, canals and ponds, according to the North Carolina Department of Health and Human Services (NCDHHS). The cyanobacteria produce toxins that can damage the kidneys, liver, gastrointestinal tract and nervous system of people, pets and livestock relatively quickly. As a result, the NCDHHS recommends that the public "keep children and pets away from waters that appear discolored or scummy."

5 signs your dog might be depressed

Low Energy

As with humans, depression in dogs is often caused by changes in serotonin levels. This manifests in lethargy and what may appear to be laziness. If your dog quickly goes from loving walks and leaping at any opportunity to fetch a tennis ball to showing disinterest in his favorite activities, he may be down in the dumps. Don’t brush this off as lazy dog behavior (unless of course, you own a basset hound, in which case Netflix and chill is very much the status quo).

Change in Eating Habits

Canines live for meal time. PetCareRx, a pet pharmacy that deals with nearly every canine medication on the planet, states dogs who are feeling low typically eat less or show only mild interest in their food. This symptom can be easier to spot since—hello!—there’s tangible evidence left over after dinner; so pay attention to these habits.

Change in sleeping habits

Again, lethargy that turns into 24/7 naptime should ring alarm bells. According to Stanley Coren, PhD, who has written almost a dozen books on dog behavior, a canine retreating to his bed or snoozing instead of playing is often an indicator something isn’t right. This could certainly be a sign your pup has hurt himself physically, but pain is often paired with yelping or a change in movement, not sleep. If nothing on the surface looks wrong, your dog could definitely be feeling depressed.

Anxious or obsessive behavior

While some breeds are more anxious and alert than others (hello, Boston terriers), any dog suddenly fixating on a certain behavior could be exhibiting symptoms of depression. Often chewing constantly on a single paw or nail can indicate dogs are upset or feeling low. If your typically friendly Goldendoodle stops greeting you at the door and starts hiding in the living room, something is definitely off internally.

Aggression 

While aggression is rarer when it comes to depressed dogs, it can happen. Depression and anxiety often go hand-in-hand, and if a pup lets that anxiety take over, it can come out as scary, mean behavior. On the other hand, some pet experts like Iain Booth, founder of VetUK, believe dogs who feel ignored will act out for attention. A combination of these factors can make for a very moody pup.
