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.

Experimental purchase
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.

Didn’t work
Didnt do anything to help keep fleas away

Excellent for very large breeds
I have a 60# fur baby. Seems like I only used half of it. there was plenty collar to fit a very large dog. It is a lightweight soft collar with no noticeable odor. She’s had her new “necklace” for a month now with 2 in between baths. during the height of flea season. I saw immediate results. I can’t believe how inexpensive it was for such an efficient flea collar that actually works. Would purchase again.
