Title Card: “Canine Kitchens Grind to Serve…And Fido is Assured of a Dog Dinner DeLuxe Delivered Daily to His Door”‘

Originally a public domain film from the Library of Congress Prelinger Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

Dog food is food specifically formulated and intended for consumption by dogs and other related canines. Dogs are considered to be omnivores with a carnivorous bias. They have the sharp, pointed teeth and shorter gastrointestinal tracts of carnivores, better suited for the consumption of meat than of vegetable substances, yet also have 10 genes that are responsible for starch and glucose digestion, as well as the ability to produce amylase, an enzyme that functions to break down carbohydrates into simple sugars – something that carnivores lack. Dogs evolved the ability living alongside humans in agricultural societies, as they managed on scrap leftovers from humans.

Dogs have managed to adapt over thousands of years to survive on the meat and non-meat scraps and leftovers of human existence and thrive on a variety of foods, with studies suggesting dogs’ ability to digest carbohydrates easily may be a key difference between dogs and wolves.

In the United States alone, the dog food market is expected to reach $23.3 billion by 2022…

Dry dog food usually consists of bagged kibble that contains 3-11% water. It makes up the vast majority of pet foods.

Dry food is both convenient and typically inexpensive, with over $8 billion worth being sold in 2010 – a 50% increase over just seven years earlier…

Wet or canned dog food usually is packaged in a solid or soft-sided container. Wet food contains roughly 60-78% water, which is significantly higher in moisture than dry or semi-moist food. Canned food is commercially sterile (cooked during canning); other wet foods may not be sterile. Sterilizing is done through the process of retorting, which involves steam sterilization at 121 degrees Celsius. A given wet food will often be higher in protein or fat compared to a similar kibble on a dry matter basis (a measure which ignores moisture); given the canned food’s high moisture content, however, a larger amount of canned food must be fed in order to meet the dog’s required energy needs. Grain gluten and other protein gels may be used in wet dog food to create artificial meaty chunks, which look like real meat…
