Description:

'Since I first drew attention several years ago to the value of yeast as a vitamin food, a good deal of discussion has resulted, and latterly its commercial possibilities have attracted the attention of quite a number of manufacturers of dog foods. Various firms in different parts of the country have started packing yeast in different forms - specimens of several brands have reached me quite recently. One brand which is conveniently prepared and packed in powder form and which I have examined carefully is "Queenwood's." This preparation deserves the attention of all dog-owners intent on trying what yeast will do in the way of providing vitamin "B" for dogs suffering from hysteria or otherwise not "doing well."'
