I don't know. I did do both for one dog for about six weeks trying to improve coat regrowth, didn't see any difference so I went back to just fish oil. I think there is more solid research to support the benefits of fish oil.
I did a search trying to find out the truth about coconut oil when it became the rave thing to do. I tried searching studies and USDA and found some data about it. I decided not to use the coconut oil after reading the research on people and the advice of the USDA.
