I purchased the Sergeant's Gold flea & tick for my dog! Biggest mistake ever! She's been itching, shaking, not sleeping, her skin is so irritated. I have to bring her to the vet because her backside (where the product was put) is oozing and she must be treated! I'm very upset that this product is on the market for anyone to use on their dog! DO NOT PUT THIS ON YOUR DOG! If anyone knows how we can put the word out BEFORE it gets used...please let me know! It's too late for my dog now! She's suffering and I'm worried!
