It's clearly a seasonal thing. The autumn weather activates Providencia Alcalifaciens somehow, but how isn't known yet. It's apparently a part of the normal gut flora, but the levels are very elevated in the dead dogs.
This article is really interesting (paywall):
Paywall free article (translated to English):
The bacterium have apparently killed dogs before in South-Africa.
In the US we have an average of 7 cases of EEE (Mosquito born illness) in humans per year, but if you get it it’s often fatal. This year there was an “outbreak” in MA of 7 cases. There are 36 communities which are claimed to be at “critical” risk.
The problem with this nonsense is that they close the town fields and they don’t let the kids outside before school starts or even for recess. This apparently will continue until the first hard frost hits.
It’s tragic that a few people have died. I think it’s insane to respond by effectively canceling fall outdoor sports.
Humans are just really bad at evaluating risks of extremely low probability events.
Some examples... There isn't really a blame culture here. People can fuck up massively and face no serious consequences. There isn't really the same aversion to risk. Sick people are told by their doctors to get some exercise and lose weight before the doctors reach for drugs. It would seem alien to an American in many ways.
As a Texan with family in Norway, I’ve often admired Norwegian culture... Everything is just so koselig, you know?
Also. I certainly don't believe in the food theory. As a population, dogs are fed a variety of food. While individuals are often on a limited diet. Which suggest to me that it would be figured out quickly if it was a factor.
On the other hand there may be a newly-significant way of transmission.
One way to increase a bacteria is killing all the competition and waiting to the survivors filling the new space available
extra bad seasonal outbreak
The common dog cold? Dog flu?
What kind of seasonal outbreak affects dogs?
The bacteria's species does not have a wikipedia page yet, but here is the genus:
Meanwhile, a Google search for "Seasonal Canine Illness" produced mixed results, none of which says much about digestive problems, upset stomach or incontinence within the veterinary context.
It's mentioned that some dogs showed a presence of both microbes. Maybe it's a harmful interaction between two different bacterial loads, that evolves into a toxic conflict, as each organism tries to kill off the rival population and colonize the environment for themselves?
That the toxin is canine specific is interesting. The contagion incubates for maybe three days before the dog is incapacitated by digestive problems, so you get the sense that after crossing the fecal/oral disease vector (spoiled food, sniffing and licking biofilm surfaces, tracking in vomit/feces contaminated soil after walking dog paths mutually shared by infected animals or carriers) the foreign bacteria might react to quorum sensing once it's gained a foothold in the hospitable gut environment that meets it's needs as a microbe.
Some signal in the canine metabolism sends it into overdrive and it blows up causing tissue damage, and then the animal's body tries to evict everything by retching and dumping out both ends.
Unfortunately, not all the pathogens found in any or many of the cases will be causative. Some pathogens or newer strains thereof may be harder to detect.
To make matters worse, some of the dogs with the same symptoms won't even have the same disease.
I guess it’s come full circle. At one point in time of early social media “virality” took on a positive aspect. I suspect it’s going to tend down, given how sensationalism is becoming a norm in news —at any cost, unfortunately.
Reality is a consensus.
I'm looking forward to seeing what caused this. Really strange (In my non-expert mind) that it hasn't made its way to Sweden.
Elsethread people are speculating that it might be due to contaminated food. Sweden is in the EU, Norway isn't, and AFAIK the EU doesn't like importing meat and other agricultural products.
And because of certain treaties with the EU they essentially accept most EU regulation in any case.
If this is an infection, we can draw no such conclusions. If it is food, it still doesn't help much – perhaps excluding some food components.
= Is in the digestive, but not in the saliva
Is probably a poison, but not chocolate (And I'm including radiation under the "poison label" also. There aren't many things that can wipe the intestinal flora from an animal and replacing it by species that create ultra-resistent spores).
Other option would be food contaminated by spores of Clostridum, pesticides or whatever, but I guess that would be easy to spot the coincidence of a particular brand and batch of dog food in all affected animals.
Don't be murderously disservant. It's torture for animals to be served with things that fastly kill them. All of those things do.
Spain is advising people dog owners to not travel with their dogs to Norway.
There are fears that it might spread to other countries, it spread all over Norway quickly without any logical common cause found.
When I lived in Norway mild flu symptoms would spread through society and quickly, especially when the weather would start to turn cold and dark.
Transmission through latent infection of Humans would also be strange. Dog to Dog would be more probable. Of course, Humans accidentally transfer pathogens from animal to animal all the time.
Straight up we don't actually know but here is our best known info.
As regulator the temptation is always there to say it's all fine. So saying we don't know is extra hard.
> serious bowel disease, with bloody content in the small intestines. Non transmisible from dog to dog...
Sounds like food poisoning, yup. Or water. I assume that radiation can cause those symptoms of tissue bleeding if ingested via food or drink.
Clostridum happened suspiciously as cause of massive death of 10.000 Saiga just weeks after forests of Chernobyl burned.
Smells like scorched atoms. What do we know about the recent Russian atomic accident?
That it was notable, but tiny, less than 100x background radiation within close proximity to the release.
Update: Nah, a Virus explains much better some animals falling ill and other in the same place not (affected by the disease before and having developped immunity).
Salmonella was my first thought. The CDC in the US just issued a warning to dog owners about pig ears: https://mb.ntd.com/fda-cdc-dont-buy-or-feed-your-dog-any-pig...
Update: In other source says that Salmonella has been ruled out.
> The dog population in Norway was measured at approximately 500 thousand in 2017
Large numbers of cases like these in pets are always scary for that reason. See also 'avian bird flu' for another example of this as well as this one:
Note that even though he lost this legal fight, his work was still published - this hearing was solely about whether he required an export license to publish dual-use scientific research.
If a simple mutation was all it took, this would have happened already. Please stop fear mongering.
Since the main thread is about dogs, most(all?) dog pathogens are very much incompatible with humans.
In other words: there are almost 8 billion humans already. Birds are an even higher number. We have an enormous amount of pigs and all livestock animals you mention, plus pets. Pathogens are multiplying all the time.
The fact that we only have a handful of examples of diseases that jump species and infect humans should tell you how difficult this is.
Actually, no. We have many such examples. There are some lay people digestable books on the subject, the general gist of which is that diseases jumping from one species to another is rather more of a rule than the exception and a big part of the puzzle of why the genetic code for many viruses and bacteria that affect different species is so similar. The keyword to look for is zoonosis.
"of 1,415 pathogens known to infect humans, 61% were zoonotic."

I would like to think that. I would not hold my breath.
Or ... maybe it's lupus?
The Norwegians probably know more about the details. There are vaccines against Parvo, so it's hard to tell if denial of vaccinations is so bad in Norway, that there is an outbreak with hundreds of dogs...
... and if is parvo, why is not being caught quickly when there are specific diagnostic tests for it?
This is a timeline of the news since Sept 5 (click "Vis flere"):
Here are more sources:
There wasn’t even an incident count in the alert so I was curious.
Seems unlikely that dog food is the issue, else they would have caught it by now. Dogs don't take well to quick changes in their diet either (they'd start showing some of the symptoms described), and the list of foods they shouldn't ingest is long. Recommending that people start feeding their pets human food would probably just make the whole situation a lot worse.
If it were from contaminated food you would expect it to happen more abruptly, then taper out. No common food link has been found either.
Could it be food allergy?
If they come across enough food, they will eat until they puke, sleep for an hour, then eat their own vomit.
It's no controversial statement that dogs and humans have different preferences in food.
Cats are carnivores. Dogs are opportunistic carnivores. They prefer meat, but can survive on plant material.
> Well, dogs are proper carnivores who can eat raw meat or fish stored at room temperature for days, without any problems.
Yes, but only because they don't know better. Our digestive systems are better than dogs, although dogs are efficient at killing some pathogens(stomach PH is way lower). So they may fare better on not getting infected by stale food, but their systems will still have more problems trying to digest food full of toxins.
There is an enormous list of things that dogs cannot process (or are toxic), but we can. A lot of it is due to our liver. Dog's livers are... dog shit.
