Does not work!

As my overall grading shows, the price is excellent given that other brands can go well into the double-digit range. Other than that, it's a faulty product. My 2 year old shih-tzu wore this collar for about a week and a half, yet now he has fleas. The collar is pretty much worthless as it doesn't prevent nor kill fleas once they latch on. by on 08/21/2014
Ultraguard Flea and Tick Dog and Cat Collars

I can not give this collar a good review because all my dogs have gotten fleas and the three cats have them now as well. So unless there is a record of when I purchased these, I am saying they have not lasted very long therefore are not working. by on 06/24/2012
