I wouldn’t. Though the number of flea prevention products found at your local pet supply store is numerous and include others such as sprays, shampoos, and spot-on treatments, fleas are very uncommon in our part of the world. This is one of the very few advantages of our cold, dry, and unpredictable climate. At Delton Veterinary Hospital, we diagnose fleas only a few times a year. The most common presentation we see is on dogs that live in straw bale houses.
The products sold over the counter are not without risk. In April, Health Canada issued an advisory about these products:
“While many people have used these products without any harmful effects on their pets, adverse reactions reported range from mild effects such as skin irritation to more serious effects such as seizures and in some cases death.”
Since the risk of contracting fleas is very low in the Edmonton area and the application of prevention products carries health risks, I discourage my clients from using them.
