    Works great!

    By Mommy2Cupcake on Jul 22, 2020

    Although our dog already takes benadryl for allergies, our vet recommended we add fish oil to help with her ongoing itchiness. It works great, and really makes a difference in her overall comfort. She enjoys the taste of it, and Chewy even has it for a cheaper price than our local pet store that recently stopped carrying it altogether. Adding it to the AutoShip we already get with her food made it even easier. The bottle does dribble and make a mess over time, so we pour it into a different container to make it easier to pour.

    Fish oil for our dog

    By Dustoff on Dec 19, 2019

    Our vet recommended this to help with his shedding. It seems to help, but is a little expensive. We have autoship with Chewy for our dog's food and treats, and found we could save about 20% by ordering this from Chewy...another WIN for us with Chewy!

    Fishy smelling

    By Fishy on Jan 20, 2020

    I did not care for the fish oil. It did not smell fresh, and my dog threw up after eating it. Try another brand.
