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.
Animal rescue volunteers launch Gaza’s first spay-and-neuter scheme
In the impoverished Gaza Strip, where most people struggle to make ends meet amid a crippling blockade, the suffering of stray dogs and cats often goes unnoticed.
Said el-Er, who founded the territory’s only animal rescue organisation in 2006, has been trying to change that. He and other volunteers rescue dogs and cats that have been struck by cars or abused and nurse them back to health – but there are too many.
So in recent weeks they have launched Gaza’s first spay-and-neuter programme. It goes against taboos in the conservative Palestinian territory, where feral dogs and cats are widely seen as pests and many view spaying and neutering as forbidden by Islam.
“Because the society is Muslim, they talk about halal (allowed) and haram (forbidden),” Mr El-Er said. “We know what halal is and what haram is, and it’s haram (for the animals) to be widespread in the streets where they can be run over, shot or poisoned.”
Islam teaches kindness towards animals, but Muslim scholars are divided on whether spaying and neutering causes harm. Across the Arab world, dogs are widely shunned as unclean and potentially dangerous, and cats do not fare much better.
Mr El-Er and other advocates for the humane treatment of animals face an added challenge in Gaza, which has been under an Israeli and Egyptian blockade since the Islamic militant group Hamas seized power in 2007. Gaza’s two million residents suffer from nearly 50 per cent unemployment, frequent power outages and heavy travel restrictions.
With many struggling to meet basic needs, animal care is seen as a waste of precious resources or a luxury at best. Mr El-Er’s group, Sulala for Animal Care, relies on private donations, which can be hard to come by.
Mr El-Er says his team can no longer keep up with the number of injured animals that they find or that are brought to the clinic. “The large number of daily injuries is beyond our capacity,” he said. “That’s why we resorted to neutering.”
On a recent day, volunteers neutered a street dog and two cats that had been brought in. There are few veterinary clinics and no animal hospitals in Gaza, so they performed the operations in a section of a pet store that had been cleaned and disinfected.
“We have shortages in capabilities, tools, especially those needed for orthopaedic surgeries,” said Bashar Shehada, a local veterinarian. “There is no suitable place for operations.”
Mr El-Er has spent years trying to organise a spay and neutering campaign but met with resistance from local authorities and vets, who said it was forbidden. He eventually secured a fatwa, or religious ruling, stating that it is more humane to spay and neuter animals than to consign an ever-growing population to misery and abuse.
Once the fatwa was issued, Mr El-Er said local authorities did not object to the campaign as a way of promoting public health and safety. The Hamas-run health and agriculture ministries allowed veterinarians to carry out operations and purchase supplies and medicine, he said.
The Gaza City municipality provided land for a shelter earlier this year. Before that, Mr El-Er kept the rescued animals at his home and on two small tracts of land that he leased.
The new shelter currently houses around 200 dogs, many of them blind, bearing scars from abuse or missing limbs from being hit by cars. At least one was adjusting to walking with a prosthetic limb. A separate section holds cats in similar shape.
The group tries to find homes for the animals, but here too it faces both economic and cultural challenges. Very few Gazans would keep a dog as a pet, and there’s little demand for cats. Some people adopt the animals from abroad, sending money for their food and care.
Over the past decade, international animal welfare groups have carried out numerous missions to evacuate anguished animals from makeshift zoos in Gaza and relocate them to sanctuaries in the West Bank, Jordan and Africa.
But there are no similar campaigns for dogs and cats, and Gaza has been sealed off from all but returning residents since March to prevent a coronavirus outbreak.
Mr El-Er’s phone rang recently and the caller said a dog had been hit by a car. Volunteers from Sulala brought it back to the shelter on the back of a three-wheeled motorbike and began treating it. Mr El-Er says they receive around five such calls every day.
