I have been giving my toy chihuahua Sentinel for a year now and it works great. It was reccomended to me by my vet, because it also helps with fleas. I have seen a HUGE difference in the amount of fleas. I went from finding a couple fleas daily to only finding a less then 5 since Sentinel took effect.

My groomer and veterinarian recommend using Sentinel together with Frontline Plus as a foolproof combo for keeping heartworms, fleas and ticks at bay!! :) VetDepot is the cheapest place to buy both! Dont forget to search online for coupon codes!

I was told that I had to be careful what I give my two 4 pound yorkies because some medications would be too strong for their systems. However, Sentinel works great! It helps with heartworms AND fleas.

Vetdepot has really good service and has fast delivery on this product. I also feel that they have the best pricing around since they are the cheapest that I could find in my local area.

This is an excellent product that we have used for over 13 years with three different dogs. Vetdepot has the best prices I have seen yet and the delivery time was very fast. We will be buying this product here in the future!

Love it; works great!
