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.

It worked, but it caused problems. I’ve bought this collar 3 times and trialed, and I know that correlation isn’t necessarily causation, but I feel it is important to put out here.Side effects; my dog experienced not one but two UTI’s after using this. He is 6 months old and with the week of putting on the collar became incontinent. After another week I took him to the vet where he was dx with a UTI. Collar broke the next day, so it didn’t last long (big dog, fast growing, snagged and ripped the plastic securement off). His symptoms cleared up, and we went on. I bought another one after this thinking that since he was feeling better he could tolerate the medicated collar again - I was wrong. The exact same slew of symptoms started within the week of applying. Wetting the kennel, incontinence at night, howling while peeing, etc. I took the collar off again, and gave him cranberry supplements on vet recommendation and it took another 2 weeks to clear up. Tried it once more and the second I saw a moment of incontinence I took it off.TL;DR I think my dog is allergic to it or experiencing an unlisted side effect.It functions for the animals who aren’t allergic to it. Be aware of your animals normal functions and watch closely for changes. He could have died if we weren’t watching the changes medically - we are new dog owners and he had a persistent fever for over 2 weeks and we didn’t catch on because we didn’t know.

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.

We just got our pooch a replacement, because his first one was So Good for So Long! He had no problems with the collar, no irritation or fleas or ticks, and the reflective surface is a safety feature for our early AM walks. I am grateful for the modest price tag; it makes keeping our dog healthy easier.

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.

I live in a heavy tick area and this colar seems to be working well. Very inexpensive

Works as intended. Satisfactory purchase.
