Sentry Pro XFT11 Flea & Tick Squeeze-On Dogs 11-20 lbs
I have used this product in the past and it works great on my dachshunds.
2 different mixed breed dogs. A small bout with fleas a month ago. Used this as a preventative and to make sure we didn't have a re-infestation. Dogs didn't mind. Didn't notice any scratching or irritation. I did notice their fur was damp with product (it was applied to the skin) for quite awhile.
This one irritated my lab's skin pretty bad. I was worried at first that she had gotten some fleas because she was scratching, biting, rolling (anything to get relief). I ended up having to wash it off after maybe 2 days, and she stopped scratching maybe a day later following the bath. I will say that I never found any fleas or ticks...so it served it's purpose it was just too harsh for my dog's skin.
