didn’t work

I have used this as a preventative measure monthly on my dog and cat(the cat one) for about 6 months now. They got fleas last month while on it, and it did nothing to help them. The numbers kept going up while within the month of giving it, getting baths, and daily brushing. I will never be purchasing this brand again. Lesson learned to just stay with frontline or better.

doesn't work

This product did absolutrely nothing in killing or reducing flea numbers. I bought on the recommendation of Chewy. Yes the house was treated, even if it wasn't there should be some reduction of fleas on the animals. If anything they are worse

Onguard Plus Nothing

I haven't had any flea issues in over 15 yrs. I have 4 dogs now just lost one to old age. So Heartbroken right now. Anyway I have 3 under 20 lb dogs and gave them 1 pill 2 days straight of 25lbs and over CAPSTAR and one Golden I bought ONGUARD PLU for her also not working. I've also been using house and dog body ADAMS spray so I have been relentless in getting rid of these flea's. To no Avail. Nothing has worked NOTHING... I'm on a fixed budget so this is really costing me money I don't have for zero results. I'm moving on to Diatomaceous Earth since i've heard good thing's about it. I will dust my front yard and inside and my pets. It's non toxic food grade so crossing my fingers this will end the nightmare that is fleas !! oh and I even bathed them all in Dawn that worked momentarily :(

Does not affect ticks

Purchased as a way to maintain ticks while hiking through woody areas. As noted in the product description, this chemical does not prevent ticks but it should kill ticks shortly after coming in to contact with the dog's skin. This wasn't the case or at least it does not work fast enough for any true benefits. Across my three dogs I found multiple ticks embedded in their skin. I can't speak on the product's ability to kill fleas as my dogs did not have them prior to using this product nor after, but I highly would advise against using this product as a sole means for controlling ticks.

Dogs are happy

This product provided economical relief from flea itchies for my dogs. It took a couple of days for the full effect. Easy to apply. Chewy shipped it super fast, as always.

Two thumbs up.

I have used for multiple years on multiple dogs in Ohio. Great product, no issues, no fleas or ticks!

Skeptical but favorite

I was skeptical because I’ve had issues with other meds but these are fantastic. We live in the middle of rural Missouri and our backyard is Forrest and it keeps the ticks off

Works great for its price.

I live in South East Texas and fleas are bad year round. They are pretty effective in combination with monthly baths with flea shampoo with a capstar before the bath and would definitely recommend as an awesome cost effective flea prevention!

Didn’t work on my dogs

It may work on other dogs, but not mine and they’re not outside dogs. It’s back to the expensive, Vet prescribed treatments.

Does not work!

Do not buy! Doesn’t actually work. I’m going to have to order different meds now. Total waste of money.
