  This is the only collar I will use of my dog. The vet got me started with this but PetRx is less expensive. by Bailey1 on 10/28/2014
• These collars do the trick

  I have been using these Preventic collars on my dog for 13 years. I have never found a tick, living or dead, on her. They do the trick. They can be a little pricey, but worth it. by BlueRidge on 04/23/2014

  I never knew what a tick was until I moved to Florida. My groomer told me she found 30 on my boy. Mind you he was on Revolution (mainly for heartworm), and after a call to Pfizer who makes Revolution I was told it only helps with one kind of tick and the tick needs to bit him in order to die! Give me a break. Then I tried Advantix as well. Don't waste your money it didn't work, and it doesn't work on fleas either. My vet told me to try this collar, and shortly after my boy was tick free. He hasn''t had one tick since I started using this. He did get fleas, but this collar specifically states it does not work on fleas. by Bubblez on 01/07/2014
