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.

Terrible - Made it worse

Used this on my Jack Russel mix. Ticks aren't really an issue where I live, so I can't really say whether or not it's effective against ticks. However, after applying my dog's fleas got worse. Incredibly disappointed. It's like it attracts fleas.

Forget about it!

I put this on my 2 dogs and it attracted more fleas then it got rid of! Since using this my dogs have gone from having a few fleas to getting infested with them. Hartz should pull this product from being sold and stop ripping people off.

will only ever buy this

I have a 7 year old 13lb Pomeranian, and have had her since she was eight weeks old. I originally used the K9 Advantix which would run up in the $60-70 range possibly more depending on where you would get it(and that was only for 2-3 month doses at a time)…long story short, I’ve been using Hartz Ultraguard Flea & Tick on her for almost 3 years now and haven’t had any issues with fleas or ticks. Compared to the more expensive stuff, I would find fleas on her ALL the time, and a tick or two would always find itself in the mix. Since she has been on this, NOTHING. I’m lucky if I find a flea or tick once in a blue moon, but that’s if we’re on hikes, deep in the woods or in high grass. Even in my back yard for hours she will not have ONE flea or tick, and I check her thoroughly each time. It’s a great cheap flea and tick product if you’re looking for one. Highly recommend!
