Your cart is empty.Tell pesky parasites to ‘bug off’ with the Hartz UltraGuard Flea & Tick Collar for Dogs and Puppies. This fresh scented, white collar kills and repels fleas and ticks on pups with necks up to 20 inches for 7 months. The water resistant design remains effective even after playtime in the rain. For continuous flea and tick protection from head to tail, replace the collar every 7 months. Directions: Remove collar from package, unroll and stretch to activate insecticide generator. Do not use on puppies under 6 weeks of age. Do not unroll collar until ready to use. Place the collar around the dog’s neck, adjust for proper fit and buckle in place. The collar must be worn loosely to allow for growth of the dog and to permit the collar to move about the neck. Generally, a properly fitted collar is one that, when fastened, will snugly slide over the dog’s head. Leave 2 or 3 inches on the collar for extra adjustment and cut off and dispose of the extra length. Consult a veterinarian before using this product on debilitated, aged or medicated pets. Sensitivity may occur after using any pesticide product for pets. Some animals may become irritated by the collar if it is applied too tightly. If this occurs, loosen the collar. If irritation continues, remove the collar and bathe your dog with mild soap and rinse with large amount of water. If signs continue, consult a veterinarian immediately. Do not use this product on dogs simultaneously or within 30 days before or after treatment of other flea and tick products. However, flea and tick collars may be replaced immediately.

My dog (a standard yorkie) had a really bad case of fleas during the late summer/early fall of 2024. It was so bad, that she barely had any fur left on her lower back & hind legs from her constant scratching & biting at those areas, due to the flea bites. I tried everything!! I bought Capstar (nitenpyram) oral pills to relieve the itching, I bought Frontline topical drops, I bought Hartz topical drops and I bought this flea collar. And out of all the remedies I had tried to resolve the problem, the flea collar was the one that worked the best. Seems like once I put the collar on her in October 2024, I didn't think about fleas again until this week (last week of January 2025) when I noticed she was beginning to scratch again. So the collar kept her flea free for 5 to 6 months. And during that time all the fur on her lower back & hind legs grew back. So this flea collar really works. I bought the original one from either Family Dollar or Dollar General ( I think it was the latter), and just now purchased the replacement collar from Amazon. Can't wait to put it on her tomorrow, once it's delivered.

I have three dogs that I usually buy the flea and tick pills for but I needed something cheaper temporarily. The pills I buy are $25 and last 3 months. The collars weren’t even $4 and are supposed to last for 7-8 months. I honestly wasn’t expecting them to do much but I was pleasantly surprised. We live in the country on a farm where they run around freely. We had been having a horrible issue with ticks. But once the collars were on for over 48 hours I’ve not gotten another tick off them. They didn’t have any fleas before I put the collars on them so I can’t say how they work for fleas. We’ve never had an issue with fleas since we moved here. I haven’t seen even one flea on them even when the pills wore off and ticks were crazy so there must not be any in the area. I did notice that one of my dogs seems to scratch more for a few days after I put the collar on him. But he doesn’t have an issue now. It’s been a couple months since they started wearing the collars and they’re doing so well that I’m thinking this is what we will do for fleas and ticks from now on. As long as they continue to work anyway. If they work for the 7-8 months it says I will have saved around $200. That’s freaking crazy! Even if they don’t work the 7-8 months they’re supposed to, it’s been well worth the money. The only issue I have had with the collars so far is when we first put them in the dogs they kept coming off them. The latch isn’t great. With my lab we tied something around the collar so it couldn’t slip back out the latch because his kept coming off. Probably with help from him. The others stayed in place after putting them back on once. It’s really not the worst problem but annoying because we would have to hunt the collar down. That’s why I gave only 4 stars instead of 5

My dog just chewed the collar off. It does not appear that any part was swallowed and her behavior so far is normal. (It's been 10 minutes, at the time of writing.) From previous reviews, it appeared that it takes a few days and up to a few weeks for the collar to be effective, so I did not think very much of her still scratching occasionally (and particularly her neck) during the first month of usage, especially since there was no sign of skin irritation. However, today, while I was taking a shower, she chewed the thing off entirely and left all the pieces at the front of her kennel. After a mild freakout and giving her plenty of extra water, I took all the pieces and lined them back up together... at this point, I don't believe she swallowed any of the pieces themselves, but I'm obviously very concerned about her having ingested the chemicals since this brand has been associated with pet death. Right now, I'm just monitoring her behavior, but will obviously be calling my vet today if anything appears amiss. All in all, I will not be purchasing this item again.
