Our updated (from 2014) ISCAID canine pyoderma guidelines have just been published (Loeffler et Vet Derm, 2025). The whole document is a bit of a monster so I’ll break down some of the key points over the course of a few posts.
Let’s start things off with surface pyoderma, which encompasses pyotraumatic dermatitis (acute…
Last week, I wrote about the use of oseltamivir in dogs and cats infected with H5N1 influenza. We have to be aware of the risk of drug resistance risks whenever we use anti-infectives, especially when the same drugs (like osteltamivir) are used in people, and assess the risks and benefits in order to “use…
For the longer answer to this question, check out the latest podcast episode I just posted on WormsAndGermsPod. For those who prefer to read the summary, here it is:
If you ask people on the street “should we use the limited antivirals we have available to treat people with flu on dogs and cats?”…
Canine heartworm (Dirofilara immitis) is a nasty parasitic infection of dogs that’s relatively rare in Canada, but it’s still a concern because of how severe it can be and because treatment isn’t easy. It’s transmitted by mosquitos (we have lots of those), but transmission is also influenced by temperature (which varies a lot in Canada…
When it comes to food safety risks with H5N1 influenza, we know it’s a problem with raw (unpasteurized) milk from cattle, so I often get asked if it’s a concern with milk from other animals, such as goat’s milk. It’s a good question. My typical response has been that we really don’t know. There haven’t…
It’s fair to say that raw pet foods have clearly been source of H5N1 influenza infections in cats, some of which have been fatal – even though sometimes it’s impossible to make a definitive link between the food and infection because of when and how the infection occurred, and what could or could not be…
A recent opinion article in the Washington Post about how to protect cats from H5N1 influenza includes some good considerations, but alongside some bad information. It’s prompted me to write a bit about pet food preparation and how it does (and does not) affect the presence of infectious pathogens (but please keep in mind while…
Over a year ago, I wrote a few posts about changes to Clinical and Laboratory Standards Institute (CLSI) veterinary antimicrobial susceptibility testing guidelines. When a bacterium is grown in a lab and tested for susceptibility to different drugs, the lab looks to these CLSI guidelines to determine whether they should consider the bug susceptible…
I get variations of this question not uncommonly from veterinarians:
A client just came in and said they/their kid was diagnosed with Dientamoeba fragilis infection and their physician said to test/treat their dog. What should I do?
On one hand, it’s nice to see physicians thinking about animal exposures. On the other hand, it sometimes…
We don’t talk a lot about antiviral resistance in animals, particularly compared to antibacterial resistance, primarily because we don’t use antivirals a lot in animals – but we do use some.
When we use any anti-infective medication, we have to think about the risks of resistance developing to that medication, and how we can try…
