Got here fast Got here faster than I thought. I am rating the delivery right now as the flee & tick season has not started yet, so I can not rate the effectiveness of the collar itself.

Thinner and cheaper made but cost more I ordered and received 2 collars. These collars are thinner and have a cheaper plastic clasp that I have to adjust the collars regularly as they get loose. We’ve been buying this type of collar every year for a few years now and this order resulted in a cheaper made collar that cost a lot more than our previous orders.

Love your collars! Love your collars!! No pesticides are great for my pup!!

Dewell flea collars are the best.... I ordered 3 Dewell flea collars to replace the Seresto collars my cats already had on for 8 months. I decided to try them because they had excellent reviews and were made with essential oils and not chemicals like the other ones. One of my cats has very sensitive skin and was continually scratching in spite of the previous collar. I had to use the flea collars because he couldn't tolerate any flea medication applied directly to his skin. I can honestly say his skin is clearing up and he is no longer scratching. Also...the collars smell wonderful!! If they made a fragrance that smelled like that I would buy it! Lol! If you are considering buying the Dewell flea collar I would strongly encourage you to do so. I'm certainly glad I did. From now on it's only Dewell collars for my kitties! And they're less than half the price of Seresto collars!!

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.
