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

I just received my collars for my dogs opened them and put them on they seemed to work for the first 10 minutes then back to scratching biting so I think these 7$ ultra flea collars don't work .

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.

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!

I have two small dogs that weigh about 7 pounds each. They are senior citizens who are very loved. Over the summer, my female canine appeared to get fleas. I've never used a collar on either one whatsoever. So I tried something different and got these collars for both dogs.Literally, in less than a month of usage, both my dogs health rapidly declined. My male dog was lethargic and lost weight for unknown reasons. My female dog became unresponsive and appeared uncharacteristically depleted. I thought they were sick from parasites and took them immediately the vet. Nothing was found in urine, feces or bloodstream samples.My male dog had it the worst. I assumed it was "his time" due to his age and intended to prepare for end of life care with our vet. My son accidentally took off the flea collar for my male dog while cuddling and I forgot to put it back on. In less than 24 hours, I saw a positive change so I kept the collar off and took the collar off my other dog, too. Its been a several weeks and they are both are back to normal. I do not believe it was a coincidence that both dogs became so incredibly lethargic and appeared ill while using the flea collars. I believe the poison was shutting down their organs and causing them a slow, untimely death.Please be extra careful if you use this product on smaller pets. I don't think it affects larger breeds the same way. Just give your little fur babies a flea bath and pass up using this flea collar. Your pet's life may depend on making that choice.

Great price. Great product. I use a pill during the intense summer/tick months, but for the remaining 9 months of the year this works perfect for tick/flea control. I use both cat and dog collars - no visible side effects. Have been using product for 2-3 years.

Cut to fit my dogs neck, not good. She kept scratching and I realized that the ends are sharp once you cut them and it was making terrible marks on her neck where it was cutting her.

Great flea and tick collar, I don’t detect a smell or odor from it. My dog didn’t have any reaction to wearing it so I assume it’s pretty safe for them. The collar is strong and lasts a few months, I love the reflective layer around it. It helps to remind me that it’s there so I don’t attach the leash to the wrong one when going for night walks.

I've used these on my Chihuahua and my Aussy papillon mix. He's about 35 lbs My Chihuahua is 5 lbs. It worked for them but my pitbull gets sores and a rash from flea collars. Make sure you stretch the collar really good to release the chemicals. Other than it really didn't last 7 months for the price couple months isn't bad
