Hmm I hadn't tried the cinnamon yet but I was going to. I'll definitely watch out for any changes it may cause Samson like it did Ida. I'm not sure about the coconut oil, if that suggestion was to be fed or to actually put it on the skin. I have never used pure coconut oil but I know my dog shampoo uses coconut oil as its cleaning agent. I use the hypoallergenic Tropiclean shampoo, its soap/fragrance free, the coconut oil is the cleaning agent. So I know you can put it on their skin just not sure if its safe to use pure coconut oil.
