Brucellosis in a dog, raw meat origin

Posted in Dogs
A recent report from the Netherlands in Emerging Infectious Diseases (van Dijk et al 2018) describes a new twist on raw feeding concerns, Brucella suis infection.  Here’s the short version of the story: A dog in the Netherlands developed fever, ascites (fluid free in the abdomen) and inflammation of the testicles.  After failing to respond… Continue Reading

Update: Canine influenza, US and Canada (May 18)

Posted in Dogs
The latest IDEXX Laboratories maps and case list are below. Canine flu continues to cause problems in some parts of the US, and is spreading in some states. California and Nevada have had active flu for a few months, but it may be abating. New clusters are popping up in other areas, most notably in… Continue Reading

Will you test my tick?

Posted in Dogs, Parasites
If you’d asked me a few years ago, I wouldn’t have said that’s a question I’d expect to get (daily). However, we’re in a different world tick-wise now, so it’s a common and understandable question, particularly because of our tick tracking efforts. The answer is no/possibly/maybe later. How’s that for a straight answer? We are… Continue Reading

Tick identification: Canada

Posted in Cats, Dogs, Horses
As part of our recently launched PetsAndTick.com information and tick-tracker website, we are offering a pilot tick identification program. We will be offering identification of ticks that are removed from animals (non-human animals, to be specific). The program will complement our tick-tracking efforts and help gather more information about expanding tick ranges and incursions of… Continue Reading

After a particularly miserable spring here (to put it mildly), it’s finally warming up, and the snow’s almost gone. That’s the good news. The bad news is that ticks are also going to start coming out and looking for food – that means looking for animals (including us). I assume there will be lots of… Continue Reading

Update: Canine influenza, Ontario (April 23)

Posted in Dogs
I’ve been holding off saying “it’s gone” but based on all the information we have at the moment, there’s no evidence of ongoing canine flu activity in Canada, at least for now. No new cases have been identified in a few weeks and we are now beyond the 28-day recommended quarantine period for all of… Continue Reading

Update: Canine influenza, Ontario (April 9)

Posted in Dogs
No news is good news… at least hopefully. The past week was quite encouraging. No new cases of canine influenza were identified in Ontario. A couple of “inconclusive” results were obtained from dogs in the Northumberland cluster that were previously positive. I approach these as essentially “weak positives,” because it means the test detected viral… Continue Reading

Lone Star ticks and meat allergy: Is there a concern in dogs?

Posted in Dogs
Lone-Star-tick-associated meat allergy is an interesting phenomenon in people that is getting a lot of attention, especially as these ticks (like others) are expanding their range.  The condition itself is one of those odd-ball quirks of nature that you’d never expect. The basic story goes like this: galactose-alpha-1,3-galactose (alpha-gal) is a carbohydrate that’s part of cell… Continue Reading

Update: Canine influenza, USA (April 4)

Posted in Dogs
I’m slowly catching up so here are last week’s data from IDEXX Laboratories on the canine flu situation in the US. The two main areas of concern remain California and Nevada. The number of new cases dropped quite a bit from the previous week. That’s encouraging, but it can be hard to interpret passive surveillance… Continue Reading

Update: Canine influenza, Ontario (April 2)

Posted in Dogs
I’ve been slow to provide an update, partly because I’ve been sick (not with canine flu) and partly because there’s fortunately less to report. Muskoka We are still testing but it’s pretty low yield. One challenge is the baseline upper respiratory disease activity in the area. There are various viruses and bacteria that cause flu-like… Continue Reading

Update: Canine influenza, Ontario (March 23)

Posted in Dogs
Windsor-Essex: Things have been quiet there for a while and this seems to be a nice success story. The two flu clusters that were active in January were contained and nothing new has been seen. Muskoka: Good progress has been made. Few new cases have been identified over the past two weeks. One problematic aspect… Continue Reading

Canine influenza disinfection

Posted in Dogs
I’m lazy so I’ll use the blog to answer a question that I’m getting a few times a day.  Today’s question: how to disinfect a veterinary clinic if there is a concern about canine influenza? The good news is that influenza viruses are pretty wimpy. They’re enveloped viruses, meaning they are covered by a fragile fatty… Continue Reading

Update: Canine influenza, US and Canada (March 13)

Posted in Dogs
United States (data courtesy of IDEXX Laboratories) Canine flu continues to cause problems in the US, particularly the west coast. Northern California (471 cases) and Nevada (207 cases) are the hotbeds. As ever, since these data are from diagnostic laboratory submissions, they probably represent the minority of cases (since most dogs with respiratory tract disease… Continue Reading

Update: Canine influenza, Ontario (March 10)

Posted in Dogs
Active canine influenza cases are still known to be present in two regions in Ontario. Muskoka A small number of dogs from the initial cluster of cases in the Orillia/Bracebridge/Gravenhurst region are still shedding the virus, as expected given this virus can be shed by some dogs for a few weeks. The dogs that made… Continue Reading

Update: Canine influenza, Ontario (March 8)

Posted in Dogs, Vaccination
Canine influenza continues to cause problems in Ontario. The central Ontario (Bracebridge, Gravenhurst, Orillia) clusters continue to be monitored, with new positives that were expected based on known contact with infected dogs. Whether these clusters have been contained (or are containable) remains to be seen. Testing and contact tracing continues. As mentioned previously, there was… Continue Reading

Update: Canine influenza, Ontario (March 5)

Posted in Dogs
The third cluster of canine flu in Ontario is a problem. While the first two, in the Windsor-Essex area, were relatively small and have been contained, the recent, ongoing central Ontario cluster is larger and more widespread. There are over 20 confirmed cases to date. However, it is very likely that the actual number is… Continue Reading

Canine influenza in Canada: New cluster

Posted in Dogs
While we had hoped that control of the two recent clusters of H3N2 canine influenza in Windsor-Essex, Ontario, meant that the province was again free of that virus, another cluster of infections has been identified, this time in Orillia, Ontario. Investigation is ongoing so the number of infected dogs is currently unclear, but as always,… Continue Reading

Update: Canine influenza, US (Feb 22)

Posted in Dogs
The table below has the latest H3N2 canine influenza numbers from IDEXX Laboratories. Some of the highlights include: Numbers continue to increase. Northern California and Nevada are the hotbeds, with northern CA cases increasing to 343 and Nevada 151. As always, these are just the tested cases, and they presumably represent a small minority of… Continue Reading

Yet another reason not to feed raw chicken

Posted in Dogs, Other diseases
As if another reason was needed, a recent study from Australia (Martinez-Anton et al. 2018 J Vet Internal Med) found a strong association between dogs that consume raw chicken meat and a serious neurological condition known as acute polyradiculoneuritis (APN).  APN is comparable to Guillain-Barré syndrome (GBS) in humans.  The main objective of the study… Continue Reading

Canine flu outbreak update: US

Posted in Dogs
While we have hopefully been able to contain our two recent H3N2 canine influenza clusters in Canada (more on that later), this virus continues to spread in some parts of the US, particularly Northern California and Nevada. Since the last update from IDEXX Laboratories on February 2nd, they have identified another 164 cases in the… Continue Reading

Salmonella in kids linked to raw pet food

Posted in Dogs, Salmonella
When we have discussions about the risks of feeding raw meat to dogs and cats, a frequent refrain is “where are the published reports of people getting sick?” While we know some illnesses occur, they tend not to get investigated to the level that they are published, which is problematic when trying to demonstrate the… Continue Reading
