If there is enough undigested protein left in it, they likely mistake it for edible material. Avoid letting a dog eat this material because it could lead to dehydration.

because dogs are stupid
Dogs may eat their vomit as a natural instinct to keep their den clean and prevent attracting predators. It could also be a way to reingest food for better digestion. However, if a dog is frequently vomiting and eating it, it could indicate an underlying health issue and should be evaluated by a veterinarian.
If you dog is eating its own faeces you should get that checked out by a vet right away.

a dog is a consumer because dogs can't produce their own foods. they have to consume (eat) other matter. Dogs are consumers just like humans are. Plants are producers because they can produce their own food.

Rabbits and dogs sometimes eat their poo because they can still smell nutrients in it that we cant. We say "ewe" but it isnt bad for them. So it is OK if it eats its poo.
No but some dogs might without knowing
Yes they do, but in their stomachs, not their mouths. Dogs eat something because it smells yummy, if when it gets to their stomachs they then decide that it tastes foul they'll throw it back up again.
