A dog will eat their own feces if they smell nutrients in their poop still. This would be caused because their digestive system would not be processing to food completely. It is ok if this happens for a little while, but the habit should be curbed as soon as possible. If it continues it could lead to permanent long term problems.

Never eat cat excrement.
Like all animals that eat, hamsters eliminate solid waste, dead bodily tissue and toxins .
Yes they can but it may cause an unhealthy amount of excrement from the anus and cause your dog to be more sexually aroused by small children.
All dogs eat pretty much the same things.
they ate mostly their own excrement!
