The liver of the dog is larger, it is equivalent to about 3% of the weight, the bile secreted is favorable to the absorption of the fat. The defecation centre of the dog is undeveloped, can't discharge feces in advancing state like other domestic animals.
The dog can well digest and assimilate protein and fat, but because chew insufficiently and the intestines are short, not having fermentation capacity, so the digestion power to the coarse fibre is bad. So should be minced, boiled while feeding the vegetables for dogs, should not monoblock, the whole feed.
