Can I give my dog Costco fish oil? Is it safe? What about vitamin E?

Updated on September 23rd, 2025

Pet's info: Dog | Cavalier King Charles Spaniel | Female | spayed | 5 years and 4 months old | 17 lbs

Can I give my dog fish oil from Costco? The dog supplements are much more costly. Will it be ok to give one softgel daily? Do I need to supplement vitamin E with fish oil?

It's fine to give dogs the human grade fish oil. Chloe can have 1,000 mg fish oil containing 300 mg of EPA/DHA combined for every 30 pounds of body weight. These pills are a little more than that, but it will be fine. She won't need vitamin E supplementation also. I hope this helps!

As long as you are feeding a formulated dog food, this is not necessary. Supplementing vitamin E, and/or fish oils may help the coat look shinier and can be helpful in certain medical conditions. Otherwise the dog food should have adequate amounts in it. For more information about choosing a well-balanced dog food, I recommend you read the short article at the link below.

I hope that helps and all is well with Chloe.

You can give human fish oil. Lily Sue can have 1,000 mg fish oil containing 300 mg of EPA/DHA combined for every 30 pounds of body weight. I'm not sure what she weighs, but she could probably have one or two tablets a day. Start with one to see how she goes. I would also consider getting pain medication from her vet. I hope this helps.

How much vitamin E should I give my dog when they're on fish oil?

There dosage of vitamin e would depend on the formulation and should be provided on the packaging. For example below is a vitamin e supplement which would be one tablet daily for a dog Chloe’s size. http://www.vrshealth.com/canine-products/?petcoach=1977955

Is 1000mg fish oil safe for my 18-pound dog's joints and coat?

Yes, that is fine to give once a day. I recommend a maximum of 750 mg of fish oil per 10 lbs of body weight in a dog. That brand if fine to give. I highly recommend using an omega 3 supplement like this to reduce joint pain and inflammation, and it will help the skin and coat also.

Is it safe to give my dog joint supplements, fish oil, and probiotics?

Hello again! If you are already giving a joint supplement and fish oil, do not give Chloe this additional supplement. Too much fish oil isn't good for her. I'd give the joint tablet and fish oil only. Cosequin is important for her to have for her joint health, and Nordic naturals fish oil is a good brand.

How much fish oil should I give my 17lb dog for EPA and DHA?

You are welcome! It is preferable that you give the 1,000mg containing 300mg of EPA and DHA per 30 pounds, but you can give a dose range between 20-55mg combined EPA and DHA per pound of body weight. With the Trader Joe's supplement, that's about 29mg per pound of body weight of the combined EPA and DHA so it's within the safe dose range. I'm sorry I wasn't clearer before, and I hope this clears up any confusion :-)

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

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.

Is human fish oil safe for dogs? How much should I give them?

Human fish oil products are safe for dogs. They are a good source of omega 3 which I use to reduce joint inflammation from arthritis. As Chacha is so small the maximum dose for her is 500 mg Fish oil daily. I usually start with a lower dose to make sure she doesn't get diarrhea and then I gradually increase it. You can split the dose also if you feed twice daily. Some people use liquid, others cut open the capsules and put the oil directly on the food. For EPA aim for 120 mg daily and DHA around 80 mg daily. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Chacha.

Does my dog need vitamin E with fish oil? Do heart supplements help murmurs?

Hello! If you are giving Chloe the fish oil, you don't need to give the vitamin E as well. Fish oil commonly contains vitamin E already to prevent spoilage. I wish there was any scientific evidence that heart supplements work! There is absolutely zero evidence unfortunately.
