Upgrade your dog's pest protection with our all-new Natural Flea and Tick Collar for Small Dogs. With a longer-lasting and waterproof design, this 2-pack of 13.8 inch collars provides safe prevention and control of ticks and fleas without the use of harsh chemicals. Our collars use advanced technology to refine essential plant oils into a PVC carrier, resulting in a safe and natural treatment collar. The collars have a nice citronella scent that usually lasts two to three weeks, and if you or your pet don't like the smell, simply open the sealed bag and use the collar two to three weeks later. In addition, the collars are cost-effective, including two flea and tick collars, a free flea comb, and a tick tweezer, all in one package, saving you both time and money. Each collar has a protection time of about 6 months, but please note that frequently playing in the rain may shorten the protection time. The upgraded collar is waterproof, with the active ingredients integrated into the PVC carrier. These ingredients are slowly released and distributed through your pet's skin oil layer, repelling pests without harming your furry friend. And our safe breakpoint design ensures that your pet can easily break free from any entanglements.
