A small group of local veterinarians have recently completed a study in which they set out to discover the prevalence of parasites in our pets.
The study was done over one year and involved almost 1000 cats and dogs – the largest ever done in Calgary.
They acquired their samples from a variety of clinics across the city and from the Calgary Humane Society. The only conditions were that the animals were living in the city and had not been de-wormed in the past six months.
The study is due to be published in 2011.

There is a higher prevalence of giardia here than in most other studies done in the U.S.A. Despite some speculation, there are zoonotic forms of giardia.
• 20-30% of playground dirt has roundworm eggs in it
• an estimated 80%+ of coyotes carry toxocara; a study by the Faculty of Veterinary Medicine at the University of Calgary is being conducted to learn the prevalence of parasites in coyotes that surround the city of Calgary.
