I use Frontline Plus, it comes in little plastic applicator bottles, break the neck and squeeze the oily fluid directly onto Tucker's skin, by parting the hair between his shoulders and down the back. It's good for 30 days, it enters his bloodstream. I worry too about using a strong pesticide on him, but I'm more worried about Fleas and Ticks so I use it. In the winter months I tend to slack off a bit, maybe do an application every six weeks.
This stuff is expensive, for 3 months supply at the vet's office it's $45. I just recently ordered it from drsfostersmith.com for $33.00. Then I get a catalog shipped with the order, and it's listed for 27.99, and the website still has the higher price.
Oh wow, I'm a pack leader now
I won't ask if I post too much, because I'm afraid you'll say yes!
