Fish Oil Dosing Chart

Please find below the maximum daily dosage for animals with osteoarthritis (310 mg/kg0,75 of EPA/DHA per day) as suggested by Dr. Bauer (J Am Vet Med Assoc. 2011 Dec 1;239(11)). Please note that while fish oil is generally benign and safe, certain side effects beyond weight gain and vomiting/diarrhea are possible and therefore you should contact your veterinarian if your animal has health issues other than osteoarthritis or if you have any other questions/concerns. Particularly, if your pet is suffering from osteoarthritis and obesity giving fish oil might not be ideal. 

Please note that the maximum dose (outlined below) is not tolerated by all animals and a lower dose may be preferable. We generally start with approximately a quarter of the maximum dose and then increase the dose slowly while monitoring for any side effects (such as loose stools and vomiting).

The dosages outlined below represents the combined dose of EPA and DHA. Quality products will display these amounts on the label. Please note that there are many different types (type of fish etc.), formulations (pump dispensers, capsules, etc.) and qualities of fish oil available. Some independent websites offer quality control for human products; however, many products are not tested. A convenient way of providing fish oil is to purchase a high quality joint diet (please contact your veterinarian for further information). Please also be aware that other ingredients included with certain fish oil formulations may be harmful for your dog. We therefore recommend that you consult with your vet prior to giving any fish oil products to your dog.

Some non-veterinary formulated supplements may not be appropriate for your dog, they can even be harmful – please contact your veterinarian whenever using such supplements to make sure they are appropriate for your dog.
