Frontline Plus does not repel ticks; it kills them after they bite the dog. It is a pesticide you are putting on your dog's skin. The skin is the largest organ of the body. From the spot you apply the stuff, the skin spreads it all over. When the insect bites, it gets the insecticide and dies.

I've just this past week started using Cedar-cide, which IS a repellant, and which is chemical free. Here is a link, I don't know if you can get it in Canada:

Three folks in Willy's Agility class use it. They have dogs, cats and horses. You must mist your dog daily with this. You can also spray the bedding. It repels fleas, ticks, lice, gnats, no see ums, and a few others. A fourth person in class also uses it on her dog, Darcy. Darcy is a cancer survivor, he has had chemo, and his mom is very cautious about using ANY chemicals on him at all. She swears by this stuff. I must say, when all 4 of them and their dogs attend, class smells nice! Ha haaa.

I've never had tick issues. This year due to the warm Spring, everyone says it is bad for ticks. I have found 2 this year, one on Willy and one on Lacey! So I have started using this. Only been 2 days, though, for me.

You can also spray it in your closets, to keep moths off the wool winter clothes!
