There’s been a lot of discussion about canine infectious respiratory disease complex (CIRDC) going around in dogs in the US recently. In the last week, I’ve already covered this from a few different angles, including what might really be going on with all the reports of sick dogs, reports of the potential involvement of

New Weird Canine Respiratory Pathogen? What Do We Know?
As concerns about an outbreak of canine infectious respiratory disease in the US continue, we’re still at a point where media hype massively outweighs any true data. Not much new has been reported recently. If anything, I’d say we’re hearing more about things being stable in different areas, that investigations haven’t turned up anything beyond…
Mystery Dog Respiratory Disease (Or Not) and Antibiotics (Or Not)
As concerns about canine infectious respiratory disease in the US have taken up most of my time lately, let’s merge that issue with what I had hoped to be the focus of the week: World Antimicrobial Resistance (AMR) Awareness Week.

Despite lots of media attention and associated fear, we’re still not sure what’s going…
Update: FIP Outbreak in Cyprus

Back in August, I wrote about a high-profile but poorly described “outbreak” of feline infectious peritonitis (FIP) in cats in Cyprus. Now, a preprint publication (Attipa et al. 2023) has come out with some interesting information, but lots of questions still remain. That’s the nature of emerging diseases – a single report…
Update: Canine influenza in Alberta (October 26)

After a recent case of H3N2 influenza was detected in a dog in Calgary (that presumably originated in the US), there’s not much to update, which is hopefully good news. Things have been quiet. On one hand, that’s a bit surprising, because flu is highly transmissible and there’s basically no pre-existing immunity in the Canadian…
Parvovirus in vaccinated dogs? Northern Ontario

We’re getting reports of potential canine parvovirus infection in vaccinated dogs in some parts of northern Ontario. Parvo is a nasty but vaccine-preventable disease, and available vaccines are very effective. True vaccine breakthrough (i.e. infection in a fully vaccinated individual) seems to be rare with canine parvo, but no vaccine is 100% effective, so it…
Human Multidrug-Resistant Salmonella Linked to Raw Pet Diets
Avian flu caused an uptick in discussion about health risks associated with feeding dogs and cats raw meat, based on the possible (and still pretty tenuous) link between raw poultry and a large number of H5N1 infections in cats in Poland.

The link between raw diets and flu infections is new, and something…
Cyprus Cat Deaths

I’ve held off writing about this unusual outbreak of cat deaths on the island of Cyprus for a few reasons, a big one being a lack of clear information, but the situation has drawn a lot of attention.
In general, when we have reports of strange disease events, there are a few scenarios to consider:…
Update: H5N1 Avian Flu in Cats in Poland (July 4), Possible Food Link?

The H5N1 avian flu outbreak in cats in Poland seems to be slowing down but the cause is still under investigation. While outbreaks often die out on their own (sometimes because of what we do, sometimes despite what we do), it’s still important to figure out what happened, to help understand the disease and ideally…
Update: H5N1 Avian Flu Spillover in Cats, Poland (June 27)

Yesterday, I discussed a situation where avian flu was suspected in the deaths of a reasonably large number of cats in Poland. “We need more information” was a big part of that, and as of today a few new pieces of the puzzle have come to light.
