Avian flu and dogs: How to protect your pets as cases of the fatal virus rise – National | 24CA News
After a canine in Ontario lately contracted avian flu and died, specialists say pet house owners ought to be extra vigilant — although the chance of transmission to mammals stays low.
The an infection pressure, known as H5N1, also referred to as fowl flu, is a extremely pathogenic type of avian influenza virus A and circulates most simply between birds. Although it’s uncommon for it to unfold to mammals, numbers are rising throughout Canada.
The canine from Oshawa, Ont., was contaminated with the fowl flu after chewing on a wild goose, after which creating “clinical signs,” the Canadian Food Inspection Agency (CFIA) mentioned Tuesday. The case was confirmed on April 1 and the necropsy, which confirmed the respiratory system was concerned within the dying, was accomplished on April 3.
Although the CFIA mentioned the chance of people and home pets contracting the virus stays low, Scott Weese, a veterinary inner medication specialist and professor on the University of Guelph’s Ontario Veterinary College, mentioned pet house owners ought to nonetheless train warning as the chance shouldn’t be zero.
“This dog could have easily been missed because if they hadn’t noticed the encounter with the bird, that wouldn’t have triggered any testing,” he mentioned. “So is this the only dog that’s been infected in Canada, or is it the only dog we’ve diagnosed? It’s hard to say.”
Overall, home pets getting contaminated with the fowl flu is uncommon, however the issue happens when “you have a lot of background noise going on,” he defined.
“If it’s a rare, one-in-a-million chance, but you get millions and millions of birds, that one-in-a-million chance starts to get more common.”
The World Health Organization (WHO) has known as the continued circulation amongst poultry regarding. During a WHO media convention on Thursday, Dr. Maria Van Kerkhove, an infectious illness epidemiologist, mentioned the transmission from poultry to mammals is “always of concern.”
“As a pathogen that has that zoonotic risk, that spillover risk, the concern is if it has that amplification aspect,” she mentioned. ” It is one thing the group takes very significantly as pathogens which have epidemic and pandemic potential.”
Hunting canine could also be extra in danger
Transmission between mammals normally occurs when an animal eats or chews on a fowl, Levon Abrahamyan, a virologist on the University of Montreal, mentioned.
“These cases are very rare, and they happen when there is very direct contact with a large number of viral particles,” he mentioned. “And this can happen with a dog or any animal, including a human, is in close contact with a high concentration of the virus.”
This is why the fowl flu has been transferred extra to the “opportunistic carnivores,” like foxes, raccoons, skunks, wild cats and ferrets, Abrahamyan mentioned.
For instance, final month eight skunks that had been discovered lifeless within the Vancouver space examined optimistic for the H5N1 avian influenza. B.C. well being officers mentioned the skunks could have contracted the virus by consuming contaminated wild birds.
In phrases of home animals getting contaminated, Abrahamyan believes searching canine are most in danger.
Duck searching in Canada is often within the fall, but when the fowl flu continues to unfold throughout the nation, the virus might nonetheless be current in September and October.
“In the case of domestic dogs, it’s very rare the dog could get it. But a dog that can be at higher risk is the hunting dog,” Abrahamyan warned. “I would highly recommend for hunters to take precautions now that we have a highly pathogenic influenza among wild birds.
“They should watch their dogs as a dead bird has a higher possibility of having the virus, as you don’t know what caused the death.”
How to shield your pet from fowl flu
The avian flu impacts all kinds of birds, like geese, swans and geese. It particularly impacts people who have a tendency to remain in flocks or congregate collectively. The virus is transmitted from fowl to fowl by means of secretions, feces and contaminated feed, water and tools, in response to the Canadian Centre for Occupational Health and Safety.
It may also be deadly, so when scavenger animals like skunks (or perhaps a canine) eat an contaminated fowl, they will additionally get the virus.
“We don’t want dogs roaming around where they have a close encounter with, say, a goose, as geese tend to stand their ground,” Weese mentioned. “Your dog goes up and barks at it and the goose will bark back. And that’s that close contact that we want to prevent.”
If there’s a park that canine house owners get pleasure from, nevertheless it’s flooded with geese this time of yr, Weese mentioned it’s in all probability not a fantastic place to take your pet, because the purpose is to “reduce that bridge between wildlife and domestic animals.”
Weese mentioned he has two canine of his personal and lives in rural Ontario, so there are geese and geese all over.
“I’m not being overly restrictive with my dogs, but I’m not going to let them go chase geese in the pond. If there’s a dead bird, I’m certainly going to keep them away and I going be more restrictive. But I’m not going to keep them completely on leash in areas where I know that we don’t see a lot of birds.”
In phrases of feeding pets uncooked meat, Weese mentioned if a canine is on a uncooked meat weight loss plan, there shouldn’t be a threat of avian flu as a result of it’s the identical as shopping for poultry from the grocery retailer.
“There’s no risk of influenza there,” he defined. “Poultry is really, really well monitored. They’re not going into the food chain if they’re infected.”
But he warned that canine house owners mustn’t hunt their very own birds to feed their canine, or have their very own yard poultry, as these are “big amplifying” sources for the virus.
Are there dangers with birdfeeders and avian flu?
As instances of avian flu steadily rise in Canada, Weese mentioned birdfeeders can pose a threat, particularly for “birds themselves, as feeders are co-mingling sites.”
“You’re bringing together birds that might not be getting close together otherwise. And you’re also creating more of that risk of the bird’s secretions and bird poop that’s on the feeder. So it might be a place where you’re going to amplify the virus if one of them has it,” he mentioned.
There is also the hazard of the fowl feeder bringing in additional animals which can be near the human and pet inhabitants.

He recommends holding cats indoors if doable however acknowledges which may be troublesome to do in some conditions.
“If you have an outdoor cat in particular, it’s probably not good to have a feeder as it creates a greater chance for that cat to catch a bird and then the cat is more likely to catch a sick bird,” Weese added.
If individuals do wish to maintain their feeder or fowl bathtub round this spring and summer season, Abrahamyan recommends washing it ceaselessly with a mix of vinegar and cleaning soap, with a purpose to keep a clear atmosphere.
“You don’t want your bird feeder or bath to become a source of the transmission of this virus, so regularly clean it and it should be fine,” he mentioned.
In December 2022, the British Columbia Society for the Prevention of Cruelty to Animals (BC SPCA) urged residents to take down their fowl feeders, warning it places birds — together with nice horned owls, bald eagles, nice blue herons, geese and geese, and crows — liable to the virus.
The BC SPCA known as on individuals to take away seed and suet fowl feeders, with a purpose to discourage birds from gathering and doubtlessly spreading the illness.
These feeders create “unnatural congregations” of birds who can cross the virus to at least one one other, or contract it from different fowl droppings on the bottom beneath the feeder as they forage for fallen seed, the group said.
