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.

Protection

Always purchased 6 months before requiring replacement of previous flea collar. Works that good! Want to make sure it's available just in case.

Don’t waste your money

Collar doesn’t work. My poor pup is still suffering from fleas. It doesn’t kill.. nor does it repel. He has more fleas now than what he started with when I bought this collar. I’m very disappointed.

Used To Work Amazingly, Can't Say The Same Now....

I really like this collar, and have purchased it a few times so far. It works well, when you use it right. In my last order, I bought 2 of these so that we had a backup when the first one was ready to be replaced, but the collar changed juuusssttt a bit since the last time we bought it. They used to be coated in powder, but now you have to stretch the collar to activate it. I didn't read the instructions, because I thought I knew how to use it, but like I said, it changed. For that reason, it didn't work, but that was my fault. I put the second one on my pup after I gave her a bath with shampoo that supposedly kills fleas, but it didn't, so I put the collar on anyways, in hopes that it would kill the fleas. But it didn't. She currently has fleas, and this collar isn't working. She's not getting any more fleas, but they aren't being repelled, either. Hartz, please change the collars back to what they were before! They used to work amazingly!

Right On Time

The only thing wrong was the large just barely fit around my dog's neck. He is a 4 year old GS. I guess I need XL next time.

Don’t waste your money

These don’t work. I had them on all 4 dogs after dawn baths and the fleas kept coming back. I also treated the house and yard. Collars still did nothing.

Life saver

I love the flea collars, they are life savers. I put one on each of my 3 standard poodles and it is wonderful. We live in a small camper due to our house burnt so we are in tight quarters. Fleas were everywhere...OMG how horrifying it was. These Hat rtz ultra guard plus are the new love of my life. forever will my poodles wear them.
