Questions & Answers

20 Customer Questions


What is the active ingredients ? Is this a generic of another brand ? Thank you.


Who is the manufacturer for this brand? It is my first time hearing of Onguard. Is it a Chewy house brand?

Answer by ChewyNov 17, 2020
Onguard Plus is exclusively made for and distributed by Chewy! We work closely with production partners to create and develop our own recipes and oversee production to ensure it adheres to our quality standards. Onguard Plus is manufactured in the United States.

Can I use this on my 3 1/2 lb Yorkie? Or is there something else you would recommend?

Answer by ChewyAug 22, 2021
The minimum safe weight is 5 pounds. Since this is a medication and it is dosed by the weight of the pet, it is very important to be at that specific weight.

is this a prescription ?

Answer by ChewyJun 16, 2021
This does not require a prescription.

Fast drying

This seems like it's fast drying and leaves no white marks on their fur. This works just as well as the higher priced flea topical solutions.

Old school

Surprised that it was necessary to mail in the proscription. Would think in these times could have used a photo of prescription and email.

No fleas

Onguard works as well as the more pricey name brands. No reactions, hair loss, or anything like that. Definitely no complaints. It gets the job done.
