Q. I estimate my dogs' weight to be around 80-85lbs. But for whatever reason I bought and applied flea med. For dogs 89-132 lbs. Will this harm them?

A. It should be okay, but I would keep a close eye on him. If you are worried you can always give him a bath, and scrub a lot of it off with a good soap. Depending on the product there are toxicity concerns, but many of the newer medications (frontline, revolution, advantage etc) should be fine with that small of weight discrepancy. Some of the "older" drug formulations would worry me, and it would be worth setting up a consultation, calling your vet, or calling ASPCA poison line for a custom consult.
