Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

For my puppy that is two months for ticks and fleas
Answer by ChewyNov 30, 2021
This UltraGuard Plus Flea & Tick Collar for Puppies is suitable for puppies 12 weeks of age and older.

does the collar come with a plastic storage container or anything to keep it stored while not in use, or do I have to provide a container for it?
Answer by ChewyApr 08, 2020
This collar will arrive in a sealed package. When ready to use, Place the collar around the dog's neck, adjust for proper fit and buckle in place. It can be worn at all times and provides 7 months of protection.

Would this be appropriate for an older small dog also?
Answer by ChewyJul 28, 2018
This product is just for intended for use in puppies, but Hartz does offer a UltraGuard Plus collar for small dogs available for purchase on their site.

Useless against fleas

Already reviewed liquid for cats as useless and this for my dog was just as useless. I would give 0 stars for sure if I could! I will never buy any Hartz product ever again!

works! Thank you

Drops were not working but this does. The more expensive Pet Armor did not work. Even if it only works for a month i still save money. The fleas are terrible because we have heat and humidity, so I am so glad it works.

Am buying again

I’ve bought Soresto before and works fine. But the price has gone up like crazy. I bought the Hartz Ultraguard and worked just the same. I did give them a flea bath and sprayed my yard for fleas because apparently cats are not afraid of my dogs and use my yard as a shortcut.

Sir Bentley's fleas

I was paying the Vet $39 a month for internal medication for fleas and ticks. I decided to try a flea collar instead, and he pays no attention to it. It doesn't bother him at all even though he has sensitive skin, and he smells nice too. We like to be protected since there are stray cats around, and you never know what can be in the grass on our walks. It's a great solution!
