Doesn't work at all. No guarantee honored here. Cost is pretty high especially since it doesn't work. Waiting like I was told didn't help and the only way to recover what I paid is to return priority mail and get a partial refund per customer service.

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.

Very pleased The Dewel natural collar is one of several natural preventative I use on my 11 yr old shih tzu. Our home is in a wooded area, and only 5 min from the beach, so he needs extra protection bc he is outside a lot in both environments. I am very pleased with the effectiveness of this collar and love the scent when it is new!

Disappointed this year.ormally I would give you Five stars… Normally I would give you Five stars the last 2 years they were great but the collars are not working this year :(. They also didn't smell as strong. Eileen Update. I didn't ask for a refund but Dewlpro refunded my order I assume because they read this review. It's rare for a company to take pride in their product and care about their customers. Great customer service.

This companies customer service is the… This companies customer service is the best, very professional, quick to respond! Ive been using these collars on my yorkie and morkie since April, great protection but i also use wondercide on them too when we go to the park. Im careful where we go, try to stay out of infested areas and they are always on a leash. So far we have not seen any ticks on them or fleas but i am careful.
