Sergeant's Guardian Flea & Tick Collar for Dogs

like I was trying to say I ordered it for small dogs because I have chihuahuas now I have clipped off the rest of the color I plan on using it for my other chihuahuas if I can clip it together and figure out a way to make them attach each other then I will let you know whether or not it does any good

first of all, let me say, i would NEVER place a flea collar on my dog. i've used them in the past, and every time, no matter what brand, within hours, my dog's nose is hot......not willing to do that to my pup. spot treatments (like frontline) are much better, warm nose only for a day, and they work pretty well. the reason i use these is, i cut them into pieces and throw a piece into my vacuum every time after emptying. any fleas i vacuum up don't stand a chance. been doing this for 40 years. i buy the biggest sized one, cut into approx 2" pieces. you're welcome
