The risks of importing (and traveling with) pets

Bridge closed.jpg

We live on an island, and sometimes life on PEI can bring various ‘Alice in Wonderland’ quirks. This past week quite a few folks traveled to the island, and probably more travelers would have reached PEI, if not for the ‘predictably unpredictable’ November weather that resulted in flight delay and bridge closure. A number of travelers brought their pets with them during their visit to PEI (i.e. once the bridge opened), and it made me ponder (not for the 1st time), the infectious disease risks associated with animal importation. Although these risks are highest from imported animals lacking a known medical history (e.g. strays, rescue animals, etc.), particularly those who come from countries with known infectious disease, these risks are still present (albeit on a reduced scale) with any type of animal importation, including owned pets.

A colleague of mine spends a good deal of time trying to eradicate the incursion of canine influenza into our fair country Canada- and he’s been remarkably successful at this ( However, every time I see an update on canine flu, I heave a deep sigh (hope someone buys that guy a beer!) and wish that the practise of importing higher-risk animals from other countries was something that either, a) didn’t happen, or b) if considered absolutely necessary, was thoughtfully considered (& vetted) prior to doing so. Since, these types of canine influenza outbreaks (or the risk of them occurring) seem largely avoidable with a bit of rational planning, i.e. imported (or adopted) dogs from countries with known flu (e.g. Asia, or portions of the U.S.A with known risk), should be isolated from other dogs for 28 days, until the risk of disease (and disease spread) has passed. 

Over the past number of years, I’ve done consults for or seen patients in Canada that are ill with diseases including leishmaniosis, coccidioidomycosis, hepatozoonosis and trypanosomiasis. These diseases may sound like the poem of the Jabberwocky, but they are in actuality infectious concerns that can affect dogs (and sometimes humans) from places outside of Canada. However, when dogs travel (with their humans) or are imported from other countries, these infectious concerns (just like with canine influenza) may ride along (or cross bridges) also.

As such, I’d gently suggest that any animal importation should be done with a degree of thoughtful consideration (i.e. risk assessment on a sliding scale), in order to minimize adverse impacts on the entire animal community (local, regional and national). Probably this is a tough ask, but as we approach the holiday season (and no…black Friday isn’t a holiday), perhaps it’s a request that’s in keeping with a sense of community, accountability and what is ‘looking a lot like Christmas’ in many parts of Canada?



Winter is Coming! (Could Leptospirosis be coming, too?)

Winter is coming (& canine leptospirosis may be more likely) … In B.C. and other parts of Canada.

On September 14th, I posted a draft map ( provided by our collaborative research team (Universities of Guelph and PEI) on Canadian canine lepto test positive incidence.

This past week, an article quoting a veterinarian in Sooke, British Columbia was released, warning dog owners about a local sick dog that had been diagnosed with leptospirosis and encouraging vaccination to prevent more sick dogs (

Test results (like those on our map) don’t equate with clinical disease in all instances, and that’s important to keep in mind. However, based on our preliminary assessment of the Canadian lepto test results, it’s also not too surprising (to me) that dogs in BC are at risk of (and are it seems) being diagnosed with leptospirosis. How many dogs are being diagnosed or are sick is quite another topic, since lepto: 1) isn’t always on dog owners’ (or veterinarians’) radar, and as such may be missed by not being considered or tested for, and 2) the lepto vaccine isn’t considered a ‘core’ vaccine in the traditional sense, and thus not used when perhaps it may be beneficial (

Lepto has been worrying me (hence the blogging), and there are few things I hate more than disease in dogs that I consider largely preventable through awareness and vaccination. The end result of that concern is that we’ll be expanding the Canadian K9 Lifetime Study in early 2019 to try and sort out a few more canine welfare troubles…or make a solid attempt on it.

Ongoing we’ll include Leptospira spp. serovar testing on puppies (and as they grow up-dogs) and also be expanding new puppy enrollment into Western Canada. We appreciate the support of those in the Canadian Veterinary Community who have helped us enroll such amazing puppies and pet-owners. We simply cannot do our work to raise awareness and help protect dogs without this- and it is our hope that you will continue to help us achieve these expanded Canadian K9 goals.

Cough, gag, hack, snort…STOP (CIRD-C spread)

Dogs who cough are a common concern for pet-owners and veterinarians. Just like in people, coughing, sneezing and hacking are frequently (but not always) associated with an infection of the lungs, trachea (windpipe), nose and/or eyes. Unfortunately (and again just like in people), it’s not possible to know just by looking or listening what type of infection (bacterial, viral, etc.) is causing the clinical signs (symptoms in people). In dogs, the myriad possible infectious causes of coughing, snorting and hacking (aka canine infectious respiratory disease complex-CIRD-C) makes things challenging. This can impact veterinarians knowing what to do to help patients feel better, AND how to prevent other dogs from becoming sick if they are in contact with those who are coughing or hacking, or in contact with those animals who are carrying bacteria or viruses without showing clinical signs (canine carriers) but are still able to pass on disease.

It’s not fun to feel ill or see those we care for get sick, and the first reaction as devoted parents of pet patients is to seek relief. This typically means heading into the veterinary clinic for diagnosis and therapy. Unfortunately, seeking aid in this way can endanger other dogs through spread of infection, i.e. dog nose to dog nose contact or cough droplets inhaled in a shared air space like a veterinary clinic lobby, treatment room, or ICU. When people (the big and little versions) are sick with a respiratory infection, most clinics will have you check in and wait at a different location from everyone else or put on a mask.  Why wouldn’t we want the same level of precaution (and protection) for our pets? …granted the mask thingie is less easily done with animals, i.e. not practical aside from trying it for fun with your dog at home and please send me pictures if you do. 

The very best thing to do when your dog suddenly (acutely) begins coughing, hacking or snorting is to contact your veterinary clinic to let them know what you are worried about BEFORE walking into the clinic with your dog. This type of ‘STOP, CALL (email or text if you prefer) and then PROCEED’ strategy with patients who have an acute onset of cough or nasal discharge can reduce spread of illness to other dogs who may happen to be in the veterinary clinic. In fact, your veterinary clinic may ask that you remain in your car with your dog and then come out to you to do an exam and ask questions to gather more information. This isn’t because they don’t like you (or your dog) it’s because they are responsible for all the other dogs who come to the clinic to be seen for various ailments- and the last thing anyone wants is to inadvertently spread an infectious disease from one dog to another causing an outbreak of something like canine flu (influenza virus) or another CIRD-C illness (outbreak links below).

So…if you’re worried about a brand-new cough or nasal drip in your dog, please CALL your veterinary clinic to alert them, relay your concerns and ask how they want you to proceed…but please STOP the instinct to hustle your dog into the clinic before doing so. Similarly, veterinary clinics appreciate your input and mentioning that you’re worried your dog’s cough may be infectious can help them remember to take steps to help your dog- and all the other K9 cuties they care for.

Here in Canada we don’t have much in the way of current publications on K9 lepto hot spots. However, due to the veterinary grapevine, willingness of diagnostics labs to share results and word of mouth, many of us are sadly aware that near the Halifax (and surrounding Nova Scotia) area leptospirosis established itself with a vengeance last fall. Portions of southern Ontario were hit pretty hard with K9 cases as well…and for both regions new cases were being diagnosed well into December 2017. That’s unusual since we don’t tend to think of lepto as a bug that does particularly well in colder climes (i.e. how we traditionally think of the Canadian winter), but times ‘they are a changin’ and at the risk of using 2 song choruses at one go, we (veterinarians) may need to ‘change, change, change’ our thinking on what vaccines are indicated for our specific geographic risk regions. 

 These days, if you live in (or plan to travel to) eastern or Atlantic Canada (and potentially coastal B.C) with your dog, leptospirosis vaccination (i.e. containing the 4 K9 lepto serovars I mentioned in the prior blog ( is something you’ll want to consider in order to protect dogs year-round. Particularly as we slide into fall and hope to avoid further outbreaks of severe canine illness. 

 On that note and to help raise awareness, here’s a draft map provided by Scott Weese and our collaborative research team (Universities of Guelph and PEI) on Canadian canine lepto test positive incidence (PCR, ELISA).
