I have a very small 3 pound Yorkie, we live in an apartment, so he doesn’t spend alot of time outdoors.

Which brand of flea and tick prevenative would you recommend?

I have used Advantage in the past. How about Frontline or Advantix?

I’m letting him wear a flea collar right now, I’ve seen the comercial for K- nine advantix, is that much better for a puppy? but wouldn’t the flea collar work just as well?

I was wondering if it works and if it has any negative side effects
i have been using the expensive stuff like advantix and front line but there is still a couple fleas and I’m going broke so i don’t know what else to do. Can fleas get immune to a certain kind of medicine?

I feel like I’ve tried just about everything! Both Frontline and Advantix don’t work on my dog’s fleas, so I’m looking for something that might. Thanks!
Just so you guys know, I was putting this Advantage on monthly. I have always been very particular about putting their topical on the same day every month, as well as giving them their heartguard. I just wanted to let everyone know that since some thought that I was just being careless with it. Thanks.

What flea preventative is the best? Is there anything besides Frontline and Advantix that actually works? What flea shampoo works?
