Dog Oil is not too slippery and does not dry out too quickly, providing the perfect medium for massage.It is for use where ever massage is beneficial. Ruth Chare, World Tae Kwon Do Champion says I use Dog Oil after a hard work out .There are no animal products and it has not been tested on animals. Originally made in 1920 by Owd Bob, Dog Oil was meant for use on racing dogs, but it has been found to be good for humans.
