Description:

'There has just been put on the market a new dog and puppy cake named "Mixavite." Its main ingredients are medicinal and cod liver oil, whole wheatmeal, dried milk, wheat germ and iodised minerals. This new food is said to be particularly rich in vitamins A, B, C, D and E. A and B are greatly concerned in the production of bone, and on this account "Mixavite" is said to help greatly in the growth and production of perfect bone, teeth and jaw formation. The iodine content of the food acts as an additional element to the functioning of the thyroid gland and as an internal disinfectant. There is also present vitamin B which has a beneficial action on the working of the boweld, [and] which has much to do in the production of healthy litters. It is said that the new food is so balanced that it contains all of the necessary ingredients to help in the growth of bone and muscle, without producing unnecessary fat and that it is a correct incentive to the proper working of a dog's internal organs.'

Description:

'I have received several letters about my "Note" of July 3rd on bitches' milk. One comes form a Scottish firm who make dog foods. They say:-

"We see in your 'Notes for Novices' in Our Dogs of July 3rd the analysis you give for bitches' milk, being interested in the sale of Full Cream Milk Food for bitches in whelp and puppies. You will see by the following analysis we received recently from the Royal Veterinary College of Edinburgh there is quite a difference from what you quoted from Chemist and Druggist,

Bitches Milk.. Total Solids, 24.6.. Proteins 11.2.. Fat 9.6.. Sugar 3.1.. Ash 0.7.

This, we take it, is more likely to be correct. As we manufacture an entirely whole wheat meal dog food, without anything being extracted or anything added, we noted with great appreciation your remarks on the feeding of dog cakes."

There is not any material difference between the two sets of figures; the basis of calculation is rather difference, and the figures I gave may be relied upon absolutely as a guide to the adjustment of cows' milk to bitches' milk.

I am glad to know that yet another firm is manufacturing whole wheat into dog food without taking anything from it. Presently, all the best dog food manufacturers will be doing the same.'
