Stray dog rabies vaccination debate
In response to an ongoing rabies outbreak, Thailand has launched a program to vaccinate stray dogs. A posting to ProMed questioned this approach.
"The authorities plan to catch stray dogs, to vaccinate them, and to release them. This is inadvisable, since rabies incubation in dogs may extend to a year, although it is mostly…
Giardia outbreak closes shelter
A Fort McMurray (Alberta) SPCA shelter has been closed because of a Giardia outbreak. Giardia is an intestinal parasite that can cause diarrhea in dogs (and other species, including people) but can also be found in about 7% of healthy dogs. Giardia infection was confirmed in four dogs in the shelter, which led to the …
Dog bites, the bad and the surprising
Dog bites are nothing new. They are extremely common and it’s not unusual to see reports of serious, even fatal, dog bites, especially in children. There have been a few reports lately that are worth mentioning.
A Pennsylvania boy was seriously bitten on the face after being invited to pet a dog at a school…

Trap, vaccinate and release programs can help…
Raw food recall: Salmonella
Nature’s Variety has recalled chicken-based raw meat products because of Salmonella contamination. After a customer complaint about "digestive problems," they tested the food and found Salmonella, prompting the recall. (For more details about the recall, click here.) In some ways, this doesn’t make a lot of sense to me. If you think…
Big gun antibiotics in pets
Antibiotic resistant bacteria are a huge problem in human medicine, and they’re an increasing problem in veterinary medicine. In pets, we are seeing dramatic increases in multidrug-resistant bacteria, some as a result of transmission from humans and some that are developing in animals. Regardless of the source, infections caused by resistant bacteria are a major…
Tiger troubles in Ontario


February 14th marks the beginning of the Chinese New Year, and ushers in the year of the tiger. Coincidentally, there’s been some publicity surrounding a tiger in Ontario that has nothing to do with a New Year or good fortune. On January 10, a 300 kilogram Siberian tiger killed its owner, 66-year-old Norman Buwalda…
Rat bite fever leads to pet store lawsuit
A Phoenix, Arizona man is suing a pet store after he contracted rat bite fever from a rat he had purchased. It’s not surprising to see a lawsuit following a serious illness, considering people in the US often try to sue for just about anything, but I’m not sure it won’t get very far.
