This a great product that has worked well and has my complete confidence.

I have been using this on my shar pei/shiba inu since April 2021 with absolutely NO issues, this year has been horrible for fleas, ticks and mosquitoes and without fail this had done its job with no problems, my mother has a sheltie and she has been using this for 4yrs with no problem as her dog has really bad reactions to most products. I had given her a bottle of this and her dog had no skin reactions using this, I had started using this when it first came out on my shiba inu as he was allergic to practically everything, I took a chance because I had nothing to lose and within a couple hrs the fleas were gone and since I had started using it there was never a tick on him and I was using this 8+yrs right up until he passed away. This will be 2+yrs of using this with my pitbull/boxer and again I have had no problems with this product to date, and just like with my shar pei/shiba inu it's done the same, it's handled the fleas, ticks and mosquitoes with no trouble. My dogs are outside all the with me and this is my go to product for when I need to protect my dogs because I have tried everything on the market and nothing, I mean nothing has come close to matching xft, I'm also not sure if one ever will. I have also recommended to many other dog owners and they were also surprisingly satisfied with how well it worked because they had only brought the expensive products with not much success as theyve put it. they didn't have much hope for this but they were completely floored with it, even more so when they paired it with the shampoo, they're exact words were "I can't believe it, how does this work better then the higher priced ones? And nevermind it when you use the shampoo, it works fantastic by itself but coupled with that forget about it." So if you were to ask me if I would recommend it on the back of yrs of me using and having other dog owners use it, my answer will always be yes. My only two gripes is that it doesn't come with a multi dewormer like other and they don't have xft for cats, other then that I couldn't ask for anything better.

It's the best collar I've ever purchased for my dog ! It gets the job done quickly .

I bought this for my rottweiler 2yrs old and she started scratching and whinning also her back legs were stiff and she wouldn't eat just was restless and miserable. I call vet and they said wash it off w dawn soap and give her benadryl. 3days later she wasn't herself yet had to take her to vet to get antibiotics and this product is terrible. My baby suffered and she could of died

Effective, budget-friendly solution to monthly pest control. I've been using Sentry Pro for four years. Now, I've learned Petco is discontinuing it and replacing it with a more expensive competitor.

My dog has been using this for 9 years, and I have never found a flea or tick on him. So I guess the products works as claimed. Totally pleased.

Bought this a little bit ago and overnight all fleas were gone!!

I purchased the item a week ago and applied it on my sweet dog. Unfortunately, he had a bad reaction to the medication. He had bumps and rash in and around his ears.
