Works very well when paired with Seresto
Purchased this to go along with the Seresto Flea Collar which seems to work 100% efficiently. Dogs were originally on Panoramis but did not take them as well as Intereceptor. (Panoramis smells like pesticides and i had to shove the pill down their throats.) They were on Interceptor as puppies. Smells like a beef treat and they love the taste! No side effects. Panoramis, alone, did do a better job keeping adult fleas off, but I feel Interceptor is much more safe and they love the taste.
