Back in the 1970's a lot of the commercially sold dog dips had a malathion base. I used it then, being young and trusting. Honestly can't say I recognized any problems at the time, lasts about 7 to 10 days with tick and flea free results. Being wiser with age and naturally skeptical, I would think twice about now. Since then we are learning that all these products may be harmful to you and your buddies, including the over the counter flea collars and spot treatments. I certainly understand the frustration with ticks and fleas! As a little kid I remember my grand dads collies coming in from timber with nasty ticks of all sizes and varieties, engorged, we dutifully picked off. Yuck! hence the Malathion, precor, sevin experiments. what I use now is the simple green sargents flea and tick soap, extremely mild, so I'm not afraid to use it every 7 days, works good,costs 2.00 bucks at the grocery store in bar form. and if the fleas get to be a problem, a little 7% sevin garden dust, in the bedding. Both as inoccuous as possible and still work. I believe that both sevin dust, and malathion, ( sometimes sold as bagworm spray), are still labeled in the fine print as pesticides for pets and livestock, and give mixing instructions. may turn out that granddads collies got the best cure, hand removal, but that was before Lyme, or at least before we knew what lyme was. As for the army, any Vietnam era advice from the army, as to how to treat anything, is laughable to me. As in do you believe they had the best long term interests of the dog at heart? Or the troops for that matter. See use of Nitofurazone on humans, or agent orange. The local animal or human doctors will only tell you what you can use that won't kill you and the dog immediately, but will kill pests, perferablly with something the pharmacuetical company sold them at a really nice markup. Long term, you are on your own, do your research, make the best informed decision you can. If one of your choices makes your lips turn blue, or your hands shake uncontroablly for a few days after application discontinue use. ( just kidding, kinda). Pete
