Great Flea & Tick Collar

We have a miniature schnauzer that is hypo-allergenic. The is one size collar, fit to neck and cut the end off, it works great, we live near the woods. Cheaper than a overpriced shot at the vet.

Sentry collar

This collar turned my dogs neck yellow... She hasn't had it long enough to know if it actually works but do not like what it does to her coat.

Worst Collar Ever!! DON’T WASTE YOUR MONEY!!

Worst Flea Collar ever made. The manufacturer should be ashamed. The collar clearly does not work. Came to me completely dried up probably did not work but maybe 30 minutes. Terrible purchase.

As soon as I took collars off within a month we had fleas!!

We have 2 dogs and 1 indoor cat. We have neighborhood outside cats that are in our yard ALL THE TIME- They must have fleas!!! GRRR. We had used these collars and eventually, they just fell off (after months) and I didn't replace (so stupid) and now we have fleas. Never again!! auto ship now!!!

Sentry Flea & Tick collar

I'll admit, it doesn't last as long as some others BUT it's the only one I've found that doesn't irritate my dog's neck & still works.
