Why do fish oil brands recommend different doses for my dog?

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 :-)

I think it has more to do with the amount of EPA and DHA per serving. With the liquid, there's likely less of these fatty acids per serving so it requires more of the product to get the recommended daily amount. Even half the amount will still be beneficial, and it's fine to do less than recommended. That's because too much fish oil can have detrimental effects on the dog's body, such as interference with wound healing. Recommended daily levels are typically low enough to prevent this from occurring, but having less than recommended is fine :-)

Great question! Oakley can get 1,000 mg fish oil containing 300 mg of EPA/DHA combined for every 30 pounds of body weight. For her weight, I would give her 3,000mg. You can get her dog specific fish oil pills from a pet store, but human ones are fine as well. I hope this helps!

The dosage range for Omega 3 fish oils for a 21 pound dog varies greatly from around 550mg to around 5,000 depending on the reason for the supplementation. Speak to your veterinarian about an appropriate dose and product for Poli.

You are welcome, I'm glad to help you! Honestly, I'd go with the Nordic naturals simply because they are gel pills. That's because they will be easy to hide in some peanut butter or meat to give your dog. The liquid fish oil should be added to your dog's food, and if he doesn't like the taste, he won't eat the food. But if you think he will eat the food with the liquid fish oil on it, you can use the RX vitamins. I think both look good personally.

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.

Since this is considered "off label use", as this is not a product designed specifically for dogs, your veterinarian would be the one to direct your specific dog in terms of using this product since its "off-label." To adhere to my veterinary license, I cannot advise off-label doses for a patient I have not examined and a client that I have not met. However, I will tell you that I would tell my clients that this is generally a safe product to give a 50 pound lab once a day. You may notice some increased gas/flatulence, and a "fishy" odor to his breath. If you notice any vomiting, diarrhea or decreased appetite, get him in to see your vet and discontinue use.
