Highly Satisfied Customer I first received one of these collars by accident. I put it on my dog and I was delighted by the results. No more scratched my and only 1 or 2 ticks the whole season. He was more comfortable immediately. This is important to me, also, because of Alpha Gal allergies. I love this product and plan to continue ordering. Thanks for a great job!

They gave me a total refund as stated on website I bought 2 collars for my 2 cats, and whilst waiting for their arrival I decided to dig deeper in to the safety of the ingredients (because I started hearing that essential oils were bad for cats). I read many different reviews from Amazon.com and Trustpilot about cats having bad reactions. Since my cats are indoor/outdoor cats I did not want to risk putting these collars on. So I emailed the company and explained my situation. Without any further conversations Dewelpro refunded all my money back. I am so pleased with the way they handled my situation. With whatever research I found on these collars, in my opinion, they seem to be safer for dogs than that for cats at any age

I've used this product for 4 years i I've used this product for 4 years i on my little Maltese. I was afraid to use a stronger collar for her little body. We live in a wooded area with lots of ticks and she likes to go out back. Never picked up a tick or a flea

Allergic reaction in cat and terrible customer service Put collar on cat and within 10 hours her neck swelled up. Contacted customer service. They challenged me and didn’t believe me. No care for the animal expresses. Finally after sending before and after shots(she hassled me also about pic qualities…it is hard to get a good pic of a stressed cat with swollen neck) she offered to refund me one collar. I had purchased 3 collars to stock up given their website mentioned no expiry if stored properly.
