Used Frontline for years and loved it. Now it is just like adding water to my dog's neck! It stopped the fleas for 2 days and now I can't redose with anything for almost 4 weeks.....Cruel! My 2 dogs are suffering so badly. $50.00 for nothing but an extra vet bill and watching my dogs suffer and chew themselves bald! Frontline needs to be sued! Such Frauds!!!!!!!!!!!!!!!!!!!!!!!!! I live in the South and yes my neck turns red. Down here we would tell the makers of Frontline Plus to Kiss our A$$! I can't believe they are allowed to continue making this garbage and deceiving people into spending...
