Hartz UltraGuard Flea & Tick Collar for Dogs and Puppies

A lot of vets say flea collars don't really work, but I've never had a flea or tick problem on any of my dogs. I'm not paying 50 dollars for a flea collar and these Hartz collars have worked for us for 40 years. I imagine that if your dog doesn't get any attention your mileage will likely vary because it relies on dogs getting petted to distribute the active ingredients over your dogs coat. So we'll stick to what has proven to us to work over many years. Good product that costs what should cost.

I’m genuinely impressed with how well this collar works for my dog. It’s lightweight, has a fresh scent, and fits comfortably without bothering him. I love that it provides up to seven months of protection, and it’s held up great even after rainy walks. Within days, I noticed far less scratching, and he’s been pest‑free ever since. For the price and convenience, this collar has become a must‑have in our routine.

So far no fleas or ticks.

I buy these often and everytime I am very satisfied with both the overall cost of this product and effectiveness.

I will never buy this again. I decided to try Hartz Ultra Guard because it had good reviews and a lot less than the other natural flea collars I have used in the past. Worst mistake ever and cost me more money in the end. I have an 8 year old Golden Doodle and I thought we were going to lose him. The chemicals in the flea collar made my dog sick. He went from running around full of energy to not eating and could barely move within a few days. I had to clean the dog multiple times because he did not have the energy to stand and use the bathroom. After taking him to the vet and running tests we finally figured it out. Its been 72 hours and he is finally able to eat about 25% of his normal amount and use the bathroom like normal. Spent Christmas day crying because I thought I was going to lose my best friend. This was not worth the $20 savings. I am sure this is not a normal occurrence but need to be mindful if your dog has or may have allergies. I hope this helps other dog owners avoid an emotional roller-coaster.

I’m giving this a five stars in hopes of this flea collar doing it’s job, I had to give a rating even though results are yet in…that said, this collar is not going around my pups neck, but into the canister of my vacuum cleaner. Fleas are everywhere this time of year. I’ve been told by folks who don’t have pets that they have seen fleas indoors and outdoors. I live in San Diego and evidently from what the Vets tell me we have one of the highest infestations in the country due to our climate..that being said both of my pups are medicated, I vacuum everyday. One of my girls is a Pitty and of course has skin allergies like many do. She is allergic to flea saliva🥹.. One day recently had her at the Vets who mention that putting a piece of a flea collar can help to reduce the number of fleas caught in canister that would have potential to escape back into the living space..hence the reason for my purchsase. The price is right so we will see how well that works.

It took some time to completely start working, like dayssss, but finally I got to see my fur baby fleas free for couple of months, but it doesn't last 7 months as advertised, I bought it on January, my dog barely goes outside but last week I felt confident that the collard would protect her and we spent the weekend away and she came back we so many fleas from my friend's backyard. I thought she was still under the protection of the collard but apparently not anymore.

So far so good. My two dogs have been going through infestation with fleas for about a month that I notice. I don’t get how. They never go outside and our apartment is clean, not sure if it’s the apartment (we recently moved into) that has fleas in the carpet or what but everytime I take them a flea bath, they go away for a day but come back even worse, I don’t get how! But after a bath, I put these collars on them, three days later they are clean and flealess as of now. Usually they get them back quick again and have eggs on them but so far so good!

Why did you pick this product vs others?: For ticks

My dog has had it on for more than 3 weeks - no improvement at all. Don’t waste your money.

My dog used to catch ticks everytime we go on walk. The product is a life changer. I haven’t find or see any ticks on him, it is been a real life saver for our household. My dog is thankful !
