I bought this due to my dog having fleas. It did not work for us. The fleas after a week were still there even after giving her multiple baths and combing fleas off. It fit well and it had a scent but not strong.

Flea n tick collar are quite good used for my puppy but I didn't think this worked as well as they said safe to use great for the value for money ni scent to it great durability

Harts UltraGuard Flea and Tick Collar for dogs helps in controlling fleas and ticks. I cannot say that it works as well as the more expensive brands, but it does help deter fleas and I have never seen any ticks on my dogs.
