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.
Man rescues 31 dogs from slaughterhouse in south-central Vietnam
A man from Khanh Hoa Province, south-central Vietnam spent VND24 million (US$1,027) rescuing 31 dogs from a slaughterhouse and is now looking for their owners.
The man, 46-year-old Do Minh Khoi from Nha Trang City, which is the provincial capital, shared the story to his Facebook page on Wednesday.
According to Khoi’s account, his two dogs were stolen while he was on a business trip in Hanoi, prompting him and his son to scour dozens of slaughterhouses between Nha Trang City and Dien Khanh District, also in Khanh Hoa Province, to find their beloved pets.
On Wednesday morning, Khoi arrived at a facility in Dien Khanh and saw dozens of dogs locked in cages, ready to be slaughtered.
He wound up buying all of them from the abattoir in order to save them.
“Many of the dogs were exhausted and lying still, while some were sticking their paws out as if they were asking me to save them,” Khoi recalled.
The man said he paid a total of VND20 million ($856) to buy the dogs and another VND4 million ($171) to transport them to his home in Nha Trang.
Khoi later posted the story on Facebook in the hope of finding each dog’s owner.
As of Thursday, two people had been reunited with their pets thanks to Khoi.
“Seeing the dogs wagging their tails when they saw their owners made me really happy,” Khoi said.
Ha Thuy Tram, 28, from Khanh Hoa’s Cam Lam District, said she lost her dog several days earlier.
Tram’s family had raised the dog for two years before it was stolen. They searched several dog meat shops and slaughterhouses in the locality after the canine disappeared.
“I discovered that my dog had been rescued after seeing Khoi’s status on Facebook, so I decided to travel all the way to Nha Trang to get my pet,” Tram said.
“I wanted to give Khoi some money to thank him for saving my dog, but he refused it.”
Khoi plans to keep the rescued canines at his home for about seven days so that their owners can come and take them home, afterward he will take the remaining dogs to a local animal rescue shelter.
“People who wish to find their lost dogs can come to my house at 30D Dong Nai Street in Phuoc Hai Ward, Nha Trang City, or call 0909473361,” Khoi said.
As of Thursday, Khoi and his family have yet to find their own lost pets.
