I had it happen with Advantage on my 7 lb malt, tried advantage 1 time and it caused a flaming red rash..I would go ahead and try and shampoo some of it off. I have been using frontline on Bentley(7lbs) and Mia(5 lbs) with no problem..but I split the dose between the 2 of them. I figure if the dose is enough for up to 22 pounds my two combined dnn't come close. I have had no problems with split dosage and have had no fleas or ticks. Always remeber to wait several days after a bath before you apply any of the flea products. Hope everything is ok..you might want to call your vet.
