For the dog owner who wants to use canola oil as a carrier oil to treat distemper: please don't use any oil that has been processed at high temperatures (canola, soybean , sunflower) as the metabolites coming out of this process are highly toxic for people and animals. Also, canola oil comes from the rape seed, which is part of the mustard family of plants. Rape is the most toxic of all food-oil plants. Like soy, rape is a weed. Insects will not eat it; it is deadly poisonous! The oil from the rape seed is a hundred times more toxic than soy oil." - See more at: http://www.shirleys-wellness-cafe.com/ConsumerAlert/Canola.aspx#sthash.hVolCBgk.dpuf.
You can use instead coconut oil gently warmed.
