I recently found some fleas on my dog, and I immediatley bathed her with flea shampoo and I also gave her a Sentinel tablet. I was wondering if the tablet only prevents the fleas or does it kill existing fleas. Should I also give her a treatment in between the shoulder blades or is that too much.
Sentinal does not kill adult fleas. It breaks the fleas life cycle by inhibiting egg development. If you have a bad fleas problem you can use advantage with it. vetcare
