I buy this one too up here in Canada from a local feed store. I squirt it on her food. It's highest mostly in omega 3, and coconut oil is good for omega 6. My vet said to buy the human kind as its better for them but she seems to do excellent on the grizzly brand. I also feed flax seeds once a day as this is also really good for their skin and coat. If you do that you gotta ground them right before you feed in a coffee grinder specifically for this, as pre ground don't have as much nutrients.I buy my fish oil from amazon.
I get either the 32 once or the 64 ounce of salmon or polluck oil in a pump bottle- both made by Grizzly (for pets) - depending on what's on sale
You need to refrigerate it though.
