Species Appropriate Diet. Your dog’s body requires a species-appropriate diet—like all species. Kibble is NOT species appropriate. Yes, a raw diet requires slightly more thinking, time, and effort than simply scooping and dumping kibble in a bowl—exactly what you would expect to do for a cherished companion and family member.
Dogs Can't Choose. Since your dog can no longer choose her own food, you and I must make morally responsible, informed, and intelligent food choice decisions.
Healthy Food = Healthy Body. The better your dog eats today the healthier she will be tomorrow (strong immune, endocrine, digestive, cardiovascular, and other systems).
Results I’ve seen since feeding a natural raw diet:
Rare ear or skin problems; soft shiny coat
Healthy weight
Bright clear eyes
Rare dental problems
Smaller stools from better digestion (no small matter with many dogs)
Some people proudly declare that dogs have evolved to obtain the maximum benefit from kibble. Clearly that thinking reflects a ginormous lack of understanding of the evolutionary process. It takes an incredibly long time for evolution to make a change that significant.
Look at the images. Top is a dog's mouth (carnivore); bottom human (omnivore).
Dog: Teeth evolved to pierce, tear, and crush
Human, cow, horse, great ape: Teeth evolved to chew and grind
Move your lower jaw left and right as if you were chewing and grinding food. The dog's jaw does not work that way (quite obvious when you look at the overlapping long canine teeth).
So, statements about dogs having evolved to eat and obtain nourishment from kibble clearly reflect the speaker's ignorance regarding evolution.
