Coprophagia in Dogs

No one likes to admit that their dog eats faeces, but many do and as a dog owner you may want to understand why they do it, and what you can do about it.

It often starts as puppies, but they can grow out of it as they get older. However if given half a chance, a lot of dogs will quite happily tuck into horse manure, cow dung, rabbit droppings or other similar offerings!

Why do dogs eat faeces?

There are lots of different theories as to why dogs eat faeces, from the straightforward “because they like the taste” to more instinctive reasons such as dogs being omnivorous scavengers and faeces containing some nutritional value such as undigested fat and protein. Although the latter is the most likely explanation, no one really knows.

One old wives’ tale, that has been largely disproved, is that it’s a response to something lacking in their diet. There are some rare medical disorders are thought to contribute to coprophagia, so if you have any concerns over your dog’s health you should always consult your vet.

Another theory is that coprophagia is a learned behaviour, caused by a puppy watching and copying their mother or friends. Sometimes bitches eat the faeces of their puppies to keep the nest area clean and free from disease and, perhaps instinctively, to prevent attracting predators to the nest.

What can be done about dog eating faeces?

If your dog is partial to eating their faeces and you’d like to put a stop to it, there are several possible solutions you can try. Try these one at a time so you can work out which, if any, are successful. However, if your dog is young, very old or has a history of gastrointestinal problems these methods aren’t recommended without consulting a vet first.

The pineapple method

There is no scientific evidence to support this method, but anecdotally some people believe pineapple prevents coprophagia in dogs. Try putting small chunks of fresh pineapple into your dog’s food. The theory is that any subsequent faeces then has an unpleasant, bitter or acidic taste, which deters your dog from eating it.

The courgette method

Again, there is only anecdotal evidence to support this method. Simply put a few diced pieces of raw courgette in your dog’s food. For the same reasons as the pineapple method, this makes their faeces far less palatable!

• If they ignore faeces, reward them with a tasty treat.
• Give your dog something else to do with their mouth! Provide a wide variety of chew toys and increase your quality time with your dog.
• Some dogs eat faeces as an attention-seeking behaviour, so ignore your dog unless you catch him in the act.
• Increase the number of feeds (not the amount of food) during the day so that your dog is never hungry and doesn’t feel the need to hunt down food anywhere else.
• In extreme cases you can try fitting a basket-type muzzle on your dog while you’re out walking, but never leave your dog alone when they’re wearing it.

Professional help for coprophagia

If your dog is only eating faeces when they’re left alone, for example at night, it is possible that there is an emotional reason for their behaviour. It could be related to them being left alone. If you suspect that this may be the case, speak to your vet who will be able to refer you to an animal behaviourist.

Equally, if you’re concerned about your dog eating faeces over a sustained period of time, it may be a good idea to enlist the help of an animal behaviourist. Your vet will be able to refer you.
