Advanced for Dogs (Lg) 21–55 lbs – 4 Mos/Box

Been buying these filters for some time. No complaints work great.

This has always worked well for my dogs. I use the same brand for my outdoor cats too. never had a flea since we started using this several years ago.

This used to be a good product. I’ve recommended it to many people. This year something changed and this product no longer works. It doesn’t work on my cats or my dogs. It’s useless. I won’t be buying again and I’ll be telling my friends the same. The fleas multiplied and laughed at this new product.

In all the spots where instructed to put the fluid my dog's skin got irritated, then dried and flaky.

Would give five stars BUT as well as it works it seems to only work for 3 weeks.

My large breed puppies are very rough so a collar product not feasible at this time. Not thrilled with the volume and initial messiness but so far seems to be working well.

Well, this surely wasn’t the best start to trying this product.Haven’t even tried it yet & It seems there is a faulty issue with the tubes themselves at the crimp area where there are little holes allowing the product to leak out.Thank goodness I was refunded or I would’ve been out a months supply.What a mess To clean..

I have bought two doses of this for both my dogs and sorry to say it has not worked. I am still finding fleas on them. I have sprayed their beds and the carpets every other day.
