What fish oil is best for my dog: human grade or pet formula?

Updated On September 23rd, 2025

Pet's info: Dog | Cavalier King Charles Spaniel | Female | spayed | 5 years and 2 months old | 17 lbs

Am I able to give my dog fish oil from Costco or is it better to stick with animal formulated fish oil? She gets Nordic naturals currently. (for pets)

I love Nordic Naturals and I always recommend using a veterinary product when available. They do tests to make sure you are giving the right amount for your dogs size. So while you can give fish oil from Costco I would stick to a veterinary formulation. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Chloe.
