My dog took Bravecto, why is he still scratching after 2 weeks?

I took my dog to Petco and he was prescribed Bravetco for fleas and ticks. It's been just under 2 weeks since he took the first (3 month) dose and he still scratches vigorously though out the day. Why, doesn't the medicine kills fleas/ticks?

You have to treat the environment as well, as fleas don't live on the dog, they live in the home. If you haven't treated your home, that could be why Kobi is still scratching. Wash his bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home. I hope this helps.
