Ontario lungworm update

Posted in Dogs, Parasites
The fox lungworm, Crenosoma vulpis, continues to be identified in dogs in Ontario. The attached map from WormsAndGermsMap shows the cases we know about. There aren’t many, but the issue of “rare vs rarely diagnosed” is important. As a relatively new (or newly identified) problem that requires specific testing, it’s easy for it to be… Continue Reading

Pre-multidrug-resistant TB in a dog

Posted in Dogs, Other diseases
A few times a year I get questions about tuberculosis (TB) in dogs, typically after a person is diagnosed with active TB and people want to know what the risks are to, and from, their dog. It’s often tough to answer those questions, because there’s limited information available. Risks exist, but how much of a… Continue Reading

American Family Physician: Enhancing Patient Care Through Time with Animals

Posted in Dogs
Here’s a case scenario in a “Curbside Commentary” from the journal American Family Physician (Mani and Weese, 2016). A 16-year-old girl and her parents presented to my office for her wellness evaluation. The patient has generalized anxiety disorder with comorbid major depression, for which she has been prescribed a serotonergic antidepressant. She is a high school student,… Continue Reading

Brucella canis and rescue programs

Posted in Dogs
A Wisconsin rescue has its dog population under quarantine after a dog that was adopted from the facility was identified as being infected with Brucella canis. Dogs at Gregory’s Gift of Hope are being tested, and any positives will presumably be euthanized. Littermates of the infected dog, which was adopted in 2015, are being traced… Continue Reading

Dog Licks…Again

Posted in Dogs, Other diseases
Every year or so, there’s a new wave of publicity/paranoia about the risks associated with dogs licking people. Often, it follows a study of bacteria that can be found in the mouths of dogs. It leads to a combination of balanced reports, sensational reports and defensive responses. What is the concern? Dog’s mouths are vats… Continue Reading

Infectious Diseases and Canine Group Settings

Posted in Dogs
The Ohio State University has launched a new website about infectious disease risks in canine group settings. The site includes a comprehensive document on risk and risk reduction strategies (which was just published last month in the Journal of the American Veterinary Medical Association), as well as owner-level fact sheets and a risk calculator to help identify specific risks… Continue Reading

Dog Bite Prevention Education

Posted in Dogs
I spend a lot of time talking about “emerging” infectious diseases. Some of these are truly emerging (i.e. new) diseases, some are conditions we couldn’t diagnose well before but now recognize more easily, and some are disease that have been there all along and are just getting more attention. However, while emerging infectious disease (especially zoonotic… Continue Reading

Infectious Disease Risk Management for Canine Group Settings

Posted in Dogs, Other diseases
Hot off the presses in the Journal of the American Veterinary Medical Association (JAVMA) is a guidance document aimed at reducing infectious disease risks in a variety of canine group settings. The paper, Risk reduction and management strategies to prevent transmission of infectious disease among dogs at dog shows, sporting events, and other canine group settings (Stull et al,… Continue Reading

Vague Disease Warning in Dogs (and Cats?) in New Jersey

Posted in Cats, Dogs
A vague but potentially interesting report from New Jersey outlines a request for information about pet deaths in the area. The Cumberland County [New Jersey] Health Department is asking for the public’s help in collecting data on reports of what it calls “sudden and unusual illness” among dogs in the county. Perhaps the most interesting and… Continue Reading

Diagnostic Crotch Sniffing?

Posted in Dogs, Miscellaneous
Dogs’ noses are used for a lot of things. Some are conventional (e.g. tracking, search and rescue, drug detection), some are a bit outside of the box (e.g. detection of Clostridium difficile, identifying floating whale poop). A recent paper in Open Forum Infectious Diseases (Maurer et al 2016) takes this to another level by investigating the… Continue Reading

Guinea Worm in Dogs

Posted in Dogs
There are a lot of gross parasitic diseases. A prime example is dracunculiasis, otherwise known as Guinea worm (Dracunculus medinensis) infection. People get infected by drinking water or eating undercooked fish contaminated with “water fleas” that are infected with Guinea worm larvae. Over a year or so, the worm grows silently in the body, with… Continue Reading

Capnocytophaga Back in the News

Posted in Dogs
Capnocytophaga canimorsus is a bit of an obscure bacterium. When I talk about it to veterinary or physician audiences, I’m usually met with blank stares – not surprising, since it’s not really mentioned in veterinary or medical school, from what I can tell. It’s a rare cause of infection, but a nasty one. The fact that it’s… Continue Reading

Worms and Germs Map Update

Posted in Cats, Dogs, Horses, Parasites, Rabies
A few years ago, we launched WormsAndGermsMap to help track certain emerging and endemic diseases. Data are entered by participating veterinary clinics, surveillance programs and the WormsAndGerms team. While we certainly can’t capture every case, we do collect some interesting information about the presence of certain diseases. Using the “Report Filter” bar on the left, you can… Continue Reading

Mapping Zoonotic Disease Emergence Risk

Posted in Birds, Cats, Dogs, Horses, Other animals, Other diseases, Pocket pets, Reptiles
Predicting the future is a dodgy proposition at the best of times. It’s particularly hard with infectious diseases, which tend not to behave as expected. Yet, it’s important to plan surveillance, education and response. One approach is to assess where certain types of problems are more likely to develop. That can help direct resources (time,… Continue Reading

Moving Dogs, Moving Bugs

Posted in Dogs, Rabies, Vaccination
I’ve written a lot about the issues of dog importation and the diseases that can sometimes “come along for the ride”. However, high risk movement doesn’t need to be international. Any movement from a high risk area can be a concern. A recent article in Canadian Communicable Disease Report (Curry et al. 2016) addresses the issue of… Continue Reading

There’s a Test For That! But, Is There a Need?

Posted in Dogs
Some diagnostic tests that are available are more of a situation of a test looking for a market rather than filling a clinical need for additional information. That complicates matters since providing new information isn’t necessarily useful if we don’t know what to do with it. In some situations, it can even lead to bad decisions.… Continue Reading

New superbug in dogs and cats: mcr-1

Posted in Cats, Dogs
A few years ago, the New Delhi metallobetalactamase-1 (NDM-1) antibiotic resistance gene attracted a lot of attention. This resistance gene can be found in (and passed between) a variety of bacteria, and bacteria possessing this gene are resistant to a wide range of drugs. A drug of last resort for those infections is colistin (a… Continue Reading

Lyme Disease and Dogs Infographic

Posted in Dogs
The Ontario Animal Health Network – Companion Animal has released a new infographic on Ticks and Lyme Disease in Ontario: What’s The Real Risk?  It’s obviously Ontario-centric but some of the messages apply more broadly. It’s important to consider what the real risk of exposure is, and that involves thinking about things like how common Borrelia… Continue Reading

Animals in Child Care Facilities: New Guidance

Posted in Birds, Cats, Dogs, Other animals, Pocket pets, Reptiles
Animals are not uncommonly found in daycares and other childcare settings. Sometimes, it’s good: animals can be entertaining, animal contact can have various benefits to children, and animals can be part of learning activities. Other times, it’s not: such as the presence of species at higher risk for shedding certain pathogens, poor management that increases… Continue Reading

Canine flu strikes again – Illinois

Posted in Dogs, Vaccination
Canine influenza has once again reared its ugly head in fairly spectacular fashion, this time in Bloomington, IL.  Apparently there have been numerous laboratory-confirmed cases, and also many suspected cases, and likely still more cases that have gone completely unreported.  It’s estimated that “hundreds” of dogs may have been affected already – it’s very difficult… Continue Reading

Raw Pet Food and Human Salmonellosis Outbreak

Posted in Cats, Dogs, Salmonella
According to an alert from the College of Veterinarians of British Columbia: The BC Centre for Disease Control is collaborating with BC health authorities, the Public Health Agency of Canada, and Health Canada to investigate an outbreak of Salmonella infections in British Columbia likely related to raw pet food. Raw pet food is food served… Continue Reading

“Show Me the Evidence”….Maybe

Posted in Dogs
When we’re faced with making decisions about treatments, “show me the evidence” is a common refrain. There are a lot of products being sold as “cures” but with little or no evidence to back up their claims. So, looking for any scientific backing is important.  One of the highest levels of evidence would be a… Continue Reading
