Tick Prevention

Tick season is upon us again. Or at least, it is now in full swing, as ticks have been found on dogs even in northern areas in the winter. Along with these ticks come conversations about what is or isn’t effective in keeping them off of our pets. Add the fact that every few years a new tick-borne disease seems to emerge—it’s not just about Lyme disease anymore— and the concern about keeping them away rises proportionately.

On the whole, the news is good. Since the relatively recent appearance of spot-on treatments such Advantix, it has become easier to control insects and other parasites (fun fact: ticks are arachnids—like spiders—not insects or “bugs”). Note that we say “easier to control.” Putting a product on your pet does not relieve an owner of the need to be vigilant!

There are so many options out there for tick prevention so be sure to get the product that best suits your life style.

Many owners are surprised to find that these spot-on treatments are pesticides, not drugs. As pesticides, they go through an approval process with the Environmental Protection Agency, not the Food and Drug Administration. As with any pesticide, there are the usual questions about their use: 1) Are these products safe, and is there a safer “natural” alternative? and 2) Is resistance becoming a problem?

As for question 1, the answers are yes to the safety question, and no to the “natural” alternatives. In 2008, the EPA studied “adverse events” in spot-on treatments as found them to be safe. The study can be found on their website.

Regarding question 2, the answer appears in a current issue Trends in Parasitology:

“No cases of confirmed drug resistance to recent external anti-parasitic drugs in ectoparasites (that means fleas, ticks, biting flies, etc.) of carnivores have been described over the past 10 years. All follow-ups that have been performed when failures were suspected highlighted many other reasons for such.” Moreover, the profession does constant monitoring for resistance.

The take-home: Use these products according to label (read it!) and veterinary instructions, especially with cats and small breed dogs. Remember: DRUGS APPROVED FOR DOGS MAY BE TOXIC TO CATS. As always, education is the best preventative: Stay up-to-date via your veterinarian.
