Hartz UltraGuard Pro Reflective Flea & Tick Collar for Dogs and Puppies, 7 Month Flea and Tick Prevention Per Collar, 1 Count

It fights a tough battle for my dog who loves being outside. It works well and is not too expensive.

It works! My dog was getting fleas every time we went to the park and no amount of flea medicine was helping with that. We got this and literally the same day she stopped itching and scratching like crazy, I bathed her as well and no more fleas showed up. I didn’t smell any strong scents coming from the collar, I found it very easy to cut and put it on her, doesn’t feel greasy. Looks just like a regular collar. She didn’t get any reactions from it either so I’d buy it again.

I have a 13 year old pitbull and I'm REALLY cautious about any flea/tick topical treatments for fear of side effects. He was picking up a tick literally every single time I took him outside and I was vehemently checking him from head to toe. I ordered this collar and so far (the last 3 weeks) it has kept the ticks off of him. It didn't irritate his skin or cause any side effects. It works good.

Really didnt work that well!!

Bought 7 collars 2 for dogs and 5 for cats. Hart flea collars attract fleas, they do not kill fleas. I've always used seresto collars and they work like magic. Collars weren't lasting full 8 months so I asked my vet. He said try different collars, maybe fleas population is developing immunity. Didn't have super high hopes with these because they seemed way too cheap to actually last as advertised. However, 11k reviews with 4 stars what would it hurt to try..... Gave everyone capstar to kill anything on them. Received the collars 2 days later and put them on. No visible fleas on my dogs or cats when collars went on. Some flea eggs, but collar should be working by the time they hatch. Figured we would be good.......11 days my animals had these collars on and the fleas exploded! The dogs had huge nests of flea eggs 2 in away from the collars and huge nest of flea eggs on their bums (not there when collars went on). The fleas were crawling all over them and me! My poor cats weren't any better with the fleas playing on their collars and crawling all over their faces. Fleas were 4 times worse then when I took the old seresto collars off. They were everywhere! Pulled these collars off received new seresto collars 2 days later. Within 4 days wearing new seresto collars no more fleas on dogs, no more fleas on cats, no more nests of flea eggs, no more fleas in the house. These may work for some, but they definitely did not work for us. Makes me wonder if reviews were skewed. Will stick with seresto, even if they quit working a month early, still way more reliable and cheaper than other options I've found.
