Hi, and thanks for answering my question. My dog has been taking Sentinel for flea and heartworm control. She seems to tolerate it well however I am concerned about thre risks. Could yo please tell me the advantages and disadvantages of taking this drug and any harmful reations or side affects? Is there a natural product that you could recommend that would control fleas etc.? Thanks so much for your time.
There is no known long term side effects from the use of sentinal. vetcare
