Flea protection was horrible

I bought 2 boxes, thinking it was going to work. I applied as directions said, my poor little dogs, they both are still miserable. It did not stop all of the bugs or fleas. It was as I did nothing at all. Very dis Satisfied, the Price was Reasonable was why, I tried. What actually will work on a small/medium Fiest ? They both have short hair, but stay outside. Fleas are eating them up, we treated our yard with Adam's Flea repellant too. We dip the dogs, with another Adam's product. No help. So, I tried these once a month treatment. No help ?

Somewhat Disappointed

Still seeing some fleas on my Pibble up to a week after applying. Could be I need the next size up though instead of faulty product.

Onguard flea and tick

I am so happy that I found this product. It seems to be working just fine, and it’s about half the cost of your regular topical treatments

didn’t work on my dog

Gave my dog a bath ensured there were no fleas applied as directed fleas were back on her in a matter of days I will give credit where it’s due and say they are not as bad as they were without it but this product in my experience dose not keep fleas off your pet

Ineffective

We live on a farm so my stock dogs are exposed to all sorts of stuff outside I put this on 5 dogs, it does not seem to have worked on any of them. After about 3 days they are scratching again.

do not recommend

I know that the fleas have been particularly bad this year. However, if you are looking for a cheap fix to your flea problem this is not it. I think my dog stopped scratching for two days after I applied it? Two weeks later I had to go buy a name brand for him because he is not getting any relief from the fleas and scratching. Save yourself time and money and buy the more expensive one from the start.

Flea Infestation even with continual use

We love Chewy but we’re wondering if we got a defective batch. We haven’t skipped a treatment and 5 weeks ago our dog was infested with hundreds of fleas. We’ve applied this treatment again, did all the things told to remove fleas from the house and yard, and we are still finding 20+ every few days on our dog. We literally can’t get them to go away. This says it kills all stages but we obviously aren’t seeing that happen.

Basically useless

I got this because my dogs had fleas. I dosed them both, and within a 2 weeks they had fleas again. I gave them the next month’s dose a little early. One week later, fleas. Again. I didn’t want to overdose them with this stuff, so I gave them both flea baths tonight; the number of fleas that came off of both of them was amazing. Long story short, this is a “flea prevention” that does not prevent fleas. At all.
