I am intrigued by coconut oil and I am interested to hear how your pup does long term. I give lucy fish oil everyday so some say that you may want to alternate fish oil one week, coconut oil one week to prevent loose stools. Also, you may want to build up to the daily dose over several weeks to prevent digestive/bowl upset. If you google luaric acid-coconut oil you will find many benefits to adding coconut oil to you pets diet as well as your own.
I have a big jar of it and once we get our first freeze here (Lucy has allergies) I may get brave and give it a try. I will tell you I have given Lucy a tiny bit on a spoon and she gobbled it up. It smells great.
