I just started a new oral med called Credelio, for fleas and ticks. It is working incredibly well. I don't like using more chemicals on them than I have to so they will only be on this until the fall when the ticks die off. My Faith had tick paralysis from a tick a few weeks ago and it scared me badly enough to start them all on this, which my vet recommended as very safe. Ally's allergies were environmental, not food or fleas, so every fall/winter she was itching like crazy.
