Flea and tick

I made the mistake of trying this I have always used advantix in the past on my 3 rotties never had a problem if a tick happen to get on or not it would die and come right off. First week of trying this one of my dog's had a tick embedded in him. Had to twist the darn thing out with twizzers. Unfortunately 2 of them have had Lyme disease in the past so was hoping this did as well of a job with tick as it says it does. Well back to the expensive stuff but I have to wait a couple weeks since I've already put this on them..

Ehhh Not worth it

We are combating a flea infestation, bought this to go with oral meds. It simply didn’t help. Even starting out with no fleas on the dog, he was covered 2 days later. It is, however, the same medication and the more expensive topicals, but neither work. Moved to Nexguard. I give up on topicals.

Works Great.

I have no clue why the negative reviews. I have used Frontline and others. This works just the same.

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.

Really works!

Onguard really does work! I've used cheaper brands but they did not work as well as Onguard.

Greasy formula

I think it has been effective so far but leaves a really greasy gritty feeling on my dog's fur. I put it down on her skin as directed but still her fur looks and feels dirty.

works as well as expensive brand

I have used this on my lab for years, the ticks just fall off of her and no skin irritation, very happy

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 :(
