Cool,Hoss!
My ferocious ankle biter has had coat and skin problems for years. At the suggestion from folks in the forum (and after researching the effectiveness of it) we started pouring a tablespoon of olive oil in her food with ever meal with vaguely positive results.
But this biotin appears to be quite effective according to this site:

"In a collaborative study with small-animal veterinary surgeons, dogs with fur and skin conditions were treated with biotin (approximately 5 mg biotin/10 kg body weight/day) for 3 to 5 weeks. In total 119 cases could be treated which were reported to show symptoms such as dull coat, brittle hair, loss of hair, scaly skin, pruritus or dermatitis. Cases requiring other treatments with e.g. glucocorticoids, were excluded from the study. In 60% of the cases all symptoms were reported to be cured after the biotin treatment and in a further 31% an improvement was noted; in only 9% no effect was recorded. All breeds responded but to a variable extent: e.g. in Poodles the response was lower (no response in 6 out of 11 cases) than in Alsatians where all improved and 14 out of 29 were completely cured. (wow!) The results confirm the favourable effect of biotin for treatment of fur and skin conditions in dogs.:"
Just ordered some from my online provider. Thanks Hoss!
