Hy guys im new , and my jack russel snuggles keep getting ticks and fleas .and ive used everything advice?

Good luck. I live in the Midwest US and I am convinced that the fleas are immune to Frontline. No joke. I have talked with many many people and everyone feels the same way- that we are wasting a lot of money on Frontline. I flea comb, vacuum my house and bathe my indoor cats to keep fleas away.
