How do you stop puppy from eating feces?

This condition is called pica, and it could be caused by various things. Consult a dog trainer or your vet for ideas on how to deal with it.

Another Answer:Dogs are natural born feces eaters. They come with the training and feces-eating background. Mother Bitch Dog licks them when they urinate, and defecate; some bitch-moms eat the feces. Allways in plain sight of the pup: this has been done before, and Mom is carrying on a long tradition. The pup's got an example of feces-eating to go on...This was the dog's lifestyle before people got into process.

First, dissuade yourself of the notion that the pup is setting out to do something to you. Waste not, want not; the dog is another species; you are kin, but dont work the same. The WNWN part has to do with watching another animal grow a lot faster than you and yours can grow. If you are lucky, you can see a whole life in your lifetime, and have the chance at responsibity for it: that is, you did it' it's yours and you created it.

THAT IS THE NATURE OF THE BEAST, and you will either live with it or spend serious time persuading the quadruped who has been here a lot longer than you why it would be in its interest not to eat feces where and when you can see it. This requires serious thought. Not easy when the carpet, wooden floor, linolium, or just where you step getting out of bed, is very near to your feet.

So on to the task of changing doggie behavior. Specifically, feces eating in the house:

The oldest breed is probabally only about 2500 years old. Breeds, by the way, are human beings' modification of the most tractable mammal ever lucked up on by Man, a relatively hairless biped with little ability to survive but for its fatally overgrown forebrain. Wild dogs do well in the wild; human beings really have a hard time of it. Non-wild dogs don't do well in the wild.
