The two-year-old dog became lethargic, thin and listless, deteriorating to the point that it was admitted to a pet hospital for a week for a blood transfusion.
“I was really worried about him,” Ms Powell, an enrolled nurse, said.
Testing confirmed Leo had ehrlichiosis, a disease transmitted through bites from brown dog ticks carrying the Ehrlichia canis bacteria.
But what worried the specialists is that Leo lives in the urban Top End, which some experts fear is becoming a new stronghold for a disease spreading like wildfire.
The first Australian case was detected in the Kimberley region of Western Australia in May last year.
By June, cases were rapidly emerging in Katherine in the Northern Territory and the surrounding remote communities.
The Northern Territory government has recorded 370 confirmed cases — 110 in the Darwin and Arnhem Land region, 149 in the Katherine region, 36 in Tennant Creek and in Alice Springs and surrounds, 75.
Experts say countless more have been left undetected in remote communities with little intervention.
“When we finally got to bring him home, [the vets] said he needs to stay inside, he’s at risk of spontaneous bleeding and he might not make it,” Ms Powell said.
“It was very full-on, very emotional.
“There were tears basically every night.”
Until the first cases were discovered just last year, stringent biosecurity controls had kept ehrlichiosis out of Australia.
Experts are still baffled by how the disease got in but, according to Professor Peter Irwin from the School of Veterinary Medicine at Murdoch University, the disease is now considered “endemic” across the NT.
“Ehrlichiosis is one of the most serious diseases of dogs in my opinion,” he said.
“It makes them very ill, and many dogs can die.
“Once it establishes into a tick population, it’s very difficult to eradicate.”
Common symptoms include lethargy, fever and cloudy eyes, which can be cleared up with antibiotics but, if left untreated, the disease can lead to blindness, uncontrollable bleeding and death.
“The problem with this disease is that dogs travel and spread infected ticks,” Professor Irwin said.
“Dogs that have moved from an endemic area of the community into the city will possibly bring ticks with them, and the ticks can then drop off.
“There have now been dogs with the disease identified in most other capitals, most as a result of travel from the north.”
Doctor Stephen Cutter, the head veterinarian at Darwin’s Ark Animal Hospital, is no stranger to the crippling disease.
He said up to 40 per cent of the dogs are infected in the remote communities of the Top End he visits on rotation.
But in August of last year, he saw his first case in a pet that had not left urban Darwin.
Arielle Giles, a vet at the Darwin Veterinary Hospital, confirmed the disease’s spread to Darwin, saying she had seen six cases in the past three months.
“It’s a devastatingly bad disease and it’s really difficult to treat,” Dr Cutter said.
“It’s basically everywhere and it’s now a matter of living with it.”
Both Professor Irwin and Dr Cutter said keeping ticks at bay is the best way to prevent ehrlichiosis.
“Because the infection is transmitted so quickly from the tick bites, the most important way of protecting your dog is to use a product, such as a collar that kills ticks before they bite,” Professor Irwin said.
It has now been five months since Leo was struck down by the tiny parasite and, while he is still getting regular check-ups and his future is looking brighter, vets can’t give the all-clear.
“Ehrlichiosis is really nasty in that it can stay hidden in the bone marrow for a long period of time,” Dr Cutter said.
Earlier this year, the NT government brought on a new coordinator to transition the NT’s response to the disease from a biosecurity threat to managing the outbreak.
“This disease is a nationally notifiable disease, which means that suspected cases of E.canis need to be reported, and free testing can be carried out on blood samples from suspected dogs,” said the chief vet at the Department of Industry, Tourism and Trade, Dr Sue Fitzpatrick.
Second Chance for a Pit Bull: Rescued from a Massive Tumor, Now Thriving
Animal shelters do incredible work giving pets a second chance. Some animals arrive at shelters in shocking condition, but they still step up to give them the love and care they need.
That was the case for a dog named Libby, who had a tumor the size of a volleyball. But now, her story has a happy ending.
In August, the Humane Society for Tacoma and Pierce County, in Washington state, took in a stray pit bull named Libby. They said the dog was “full of life” and had a “sweet face and kind eyes.”
However, Libby also had a serious medical concern: a 10-pound tumor the size of a volleyball, one of the largest masses they had ever seen:
Libby arrived at a hectic time for the shelter: HSTPC says Libby was just one of three urgent cases they responded to in 48 hours, and as Washington’s largest-intake shelter dozens of new animals were arriving every day.
Despite that, they resolved to give Libby the best possible care, even though they weren’t sure what the future had in store for the poor dog.
“She deserves the most compassionate care possible, but we don’t know what her outcome will be at this time,” the shelter wrote in August. “Our veterinary team is working on every possible option and will start with testing to understand what kind of tumor Libby has. For now, she is receiving pain medication to ease her discomfort and endless love from our staff.”
After giving Libby an x-ray, they discovered the tumor was in the bone of her upper right leg, and would require amputation. Reactive inflammation caused the tumor to swell to its unusual size, and was causing her agonizing pain.
Through generous donations from supporters, the shelter was able to pay for Libby’s leg amputation. The surgery, done by the vet staff at BluePearl Pet Hospital, was a success and Libby was finally free of the pain she had been living through.
Sadly, even though her tumor was gone, she was diagnosed with aggressive bone cancer, and her time on earth might be limited. But in happy news, Libby has found a home!
According to HSTPC, a vet tech fell in love with Libby and agreed to adopt her. Even though she knows that Libby might not live long, she wanted to fill her remaining days with love.
“There’s something in her eyes that begs for love and safety,” her new adopter said, according to a Facebook post. “I couldn’t turn away from that.”
Libby has now been renamed “Wiggles” and is enjoying her new home, playing with her dog brother and family and taking lots of cozy naps on the couch.
“Though we’re uncertain how much time she has left, we know she’ll spend her remaining days
