Bad reaction to Sargents Gold Flea and Tick!? WARNING!?

Last evening I applied Sargents Gold Flea and Tick to my two dogs(one rat terrier and one Chihuahua mix, I applied according to the directions on the package. With in an hour both dogs were sick. The Rat Terrier had itching so bad that she was rolling on the floor finding anything to rub her back on. We realized she was having a bad reaction to the 'medication' and bathed her immediately. We noticed the Chihuahua licking the air a lot but at first we were not too concerned and took both dogs to bed. About ten minutes later I noticed a giant wet spot on the bed, my dog was drooling everywhere, I went and bathed her too. Thats when I got on the internet to look up this thing that was POISONING my dogs! It turns out I am not alone, not even close! I read the posts that I found and they all said wash the dog with dish soap to remove the chemicals, I re-washed both dogs with that. Both were still showing symptoms horribly itchy and restless refusing to settle down, like they had invisible things crawling on them, my chihuahua still drooling and vomiting foam. Finally at about 3 am, nearly 7 hours after application they finally went to sleep, although I think it was just from exhaustion. The Rat Terrier woke up still violently itchy and miserable, but happy to say she seems better this evening although she seems to have a strange foot twitch still affecting her. The Chihuahua after some watered down chicken broth to restore fluids seemed okay by morning. A very scary night, we are just hoping that there is nothing long term with the leg tick. Please do not use this product on your pet, it is dangerous!! Any one else have a similar story to share about this awful product?
