I don't know about giving olive oil? i supplement Charlie with Nordic Naturals Pet Cod Liver Oil, and have a sample of Nordic Natural Omega-3 Pet soft gel. I corresponded with Nordic Natural and was advised not to give animals human grade fish oils.
Also, Charlie is 10 lbs. and receives 1/4 tsp. once a day of the cod liver oil. Be careful not to give too much or it will upset their tummy. |
