Is it safe to give my dog a higher fish oil dose for heart disease?

Updated On September 23rd, 2025

Will higher doses of fish oil help prevent heart disease? I'm currently giving my 17 pound dog 225 Mg. of EPA and DHA daily. Should I double this since she is prone to heart disease? Thanks!

No, higher doses of fish oil will not help prevent heart disease. Doubling up her fish oil can actually have detrimental effects on your dog's health, including interfering with wound healing and interfering with the inflammatory response of the immune system. To be honest if a dog is genetically prone to developing heart disease, there is nothing to prevent that from happening. If it's in her genes, supplements will not change genetic expression. I would not give your dog double doses of fish oil.
