However, the premium brands of dog food have the advantage that one can feed the dog less and still get very good nourishment. In addition, stool size and amount is generally less with the premium dog foods. Keep in mind that feeding dogs is partly art, and partly science. The dog food manufacturers have done the science part. The rest is up to you.
Some people feed their dogs a mix of canned and dry food twice a day.
Others feed only dry and allow free feeding, and so on. Be sure and pick a frequency of feeding, brand, and type of food to suit your dogs needs. For working Siberians, something equivalent to a Science Diet Performance is in order. For Siberians that go for walks and hikes, a Maintenance formula is usually best. Consult your breeder and veterinarian for advice.
