This is quite a common problem that we get asked about - particularly in young dogs. Coprophagia ( copro = poo, phagia = eating) is normal in some species. Rabbits cannot digest all their food in one go, and so the first set of faeces (called caecotrophs) are eaten almost straight away and the rabbit then has a second digestive crack at it in order to get the full nutritional benefit.
Cows don't eat their own poo, but will regurgitate their food to have another chew at it and process it repeatedly like this before it goes on to be digested.
It is REALLY common for dogs to want to eat the poo of other species. Often carnivore poo (eg cat or fox) is seen as the ultimate in "snack" for them, and herbivore poo (eg sheep or cow) can be just as tasty. The bottom line is, dogs like to eat this kind of poo because..... IT TASTES NICE! To the dog at least.
Carnivore faeces does contain some degree of undigested meat protein and it is this that is likely to be appealing to your dog. Evolutionary wise this scavenging probably evolved so as not to waste vital energy and nutrients. In reality, herbivore poo doesn't really contain anything useful to your dog...
In all likelihood, your dog probably won't come to any harm by eating the poo of other species - other than it being quite unappealing for their owners! However there is some risk of problems.
This is a really common behaviour in young dogs. Very occasionally it can be done due to a nutritional problem or a dietary imbalance, but this is actually REALLY RARE. Interestingly:
A puppy may start eating poo because it is inquisitive. The owners are appalled by this and rush over and try to distract the puppy by either talking to it, offering it alternative food or a favourite toy. Quite often the puppy then works out that this is a great way to get more food or attention and so will keep doing it!
So, our top tips for trying to resolve this vice:
Other than for attention, we also see dogs that eat their faeces for other reasons.
We really think you should be thinking about veterinary involvement if:
