I was recommended to put evening primrose oil in with Max's food - he dropped his coat following surgery on his tail. Whether it's just growing back anyway but I have to say his coat is thickening back up. Been about three weeks - month and still some to go but definitely improving!
People did mention rubbing vitamin e on his tail (where it had been shaved) but I didn't try that.
Brushing was another thing daily to stimulate growth by removing the dead hair - but do that daily anyway!
