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

I’ve been using the Hartz UltraGuard Pro Flea & Tick Collar on my dog for a few months now, and I’m really impressed with how well it works. We live in a wooded area where ticks are a constant concern, and since putting this collar on, I haven’t found a single flea or tick on him. The 7-month protection is a great value and lasts well through the season.One feature I love is the reflective strip—it adds extra visibility during our evening walks, which gives me peace of mind. The collar is easy to adjust and doesn’t seem to bother my dog at all. It has a faint scent at first, but it fades quickly and isn’t overpowering.

Excelente,muy bueno

Ok, so here is a hint. If it's not working stretch the collar more! About 4 or 5 days in I was ready to scream. I took the collar out of the package, pulled on it a few times and placed it on my dogs neck and every day... it did notta! advantage was always my go to but this year the fleas in my area are insane. dawn bathes, killed the living but once i took her out shed have another dozen on her. fine combing was another little horror show but then I thought maybe i didnt pull on it hard enough so took it off her and played tug of war with the collar and put it back on her, it worked! fleas are gone at least for the moment!

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.

Worked great

Didn't help at all

Flea free!!

GREAT COLLAR AND DIDN'T LEAVE CHEMICAL BURNS ON MY DOG.
