Dogs Eating Faeces


        

The Problems and Treatment of Dogs Eating Faeces

Coprophagia is the medical term for when a dog eats either its own faeces or that of another animal. There are three types of Coprophagia…

  1. Autocoprophagia eating its own faeces…
  2. Intraspecific Coprophagia eating faeces from within its own species ie another dog.
  3. Interspecific Coprophagia eating faeces from another species (ie cat, deer, rabbit, horse, etc)

dogs coprophagiaInterspecific Coprophagia is the most common version of this trait. The cause of this behaviour is not fully understood, these are some suggestions and theories

Allelomimetic Behaviour: The dog observes either the nursing mother cleaning up the faeces and urine in their the first 3.5 weeks, especially if the pup is one of the first born.

Therefore the eyes open the soonest and he can see the mother stimulating and eating his siblings faeces. 

Another common reason is seeing the breeder or its owner picking up the faeces, and copies this behaviour.

Monkey see monkey do. A very good reason not to clean up when the dog is present

Attention Junkies: The owners may scold or shout at the dog, despite being a being a negative reaction it is attention all the same.

Which is what some dogs may crave. Therefore it may be advisable to pick up the faeces especially in the home area such as the garden, out of sight of the dog.

Genetic: the dog dates back to the Mesolithic period some 15000 years ago and fed off our middens and latrines therefore faeces (poo) was a staple diet. They are still very fond of human faeces.

"In part of the Indian subcontinent you can see village dogs following naked children about waiting for them to defecate, so they can claim there prize. In parts of Africa when a baby is born they present it with a puppy as a botty-wiper. To prehistoric dogs our middens, latrines and village dumps must have appeared like manna from heaven.! (from my article the origins of modern dogs)

Taste: taste may be a factor. This is the likely mechanism in interspecific coprophagia such as eating cat faeces.

Maternal behaviour: A bitch with puppies has to stimulate the pups to toilet in the first 3 or 4 weeks. She then eats and drinks the resulting faeces/urine, therefore keeping the den clean and preventing the scent of the faeces from attracting predators. The pups see this and copy. Monkey see monkey do again.deer dung

Food or Medical: Some people recommend changing to a food with less protein, or some other nutrient may be missing from their food especially if they are Autocoprophagic or Intraspecific.

Sometimes the richer the food the more chance that the dog may find the faeces palatable.

I have recently found that dogs on Burns dog food, rather than other brands appear to sometimes eat their own or other dogs faeces.

Therefore there could be something missing that the dog needs in its diet? Though I have to say thos is difficult to say.

Either that or certain ingredients are creating the problems. It may even be making it more palatable.

Medical issues especially in older dogs such as pancreatic or intestinal problems could stimulate Coprophagia.

Even overfeeding especially food with a high fat content can sometimes spark this behaviour.

Poor quality food could also be an issue if you feed Kibble (dry food) make sure it is of a high quality and not full of additives preservatives, colourants, and ethoxyquins. See my article on Food and Behaviour.

It has also been suggested that eating faeces could be an aid in food digestion, in other words a probiotic which encourages healthy flora in the gut.

SOME TREATMENTS

Deterrent: This is a powder given to a dog with its food it is supposed to make the faeces distasteful.  You can buy it over the counter or click on the link. I cannot state that this works as I have never used it. Obviously this would be for dogs that were eating their own faeces or the faeces of another dog in the same household.

Some people put chilli sauce or mustard on the faeces in the hope that it will deter the dog. One of the best treatments is to simply pick up the faeces. Lack of access can sometimes break the cycle. This is obviously more difficult in cases of Inter/Intraspecific behaviour as you would normally be unaware of where the faeces are going to be.

Positive and Negative Reinforcement: This is the process of reinforcing another behaviour Instead When the dog is about to begin eating the faeces, the owner can then use a number of techniques and commands.  "Leave it", "Off ", "No", etc.. Or using food as a lure though in some cases the dog may combine the lure and praise as something it gets when eating faeces.

dogs coprophagiaSimple aversion therapy can be done by letting the dog approach the stool on a long lead. If he starts sniffing it, give a leash check with something like a Jingler (see my website) or a noise aversion device such as training discs or a plastic bottle with shingle can be rattled.

programmed before use and this should be done by a qualified behaviourist who understands how to program noise aversion therapy devices.

If the dog ignores rather than eating the faeces then praise and treat immediately.

If as in the previous cure the dog is “Autocoprophagic” i.e. eating own faeces then a method that sometimes works is to feed your dog pineapple extract or slices or pumpkin seeds.

Garlic extract – due to its odour or Capsicum Oleoresin – which is very hot to the taste, or give iron tablets.

These all apparently make their faeces foul tasting. Not something even in the depth of scientific analysis do I intend to test for myself.

This can work with some dogs will depend on how obsessive the dogs need is to eat the faeces. The more obsessive the dog the more difficult it is to treat the problem.

There are some health implications to coprophagia. It is not merely a nasty habit, which we see as vile and disgusting; in most cases it causes no real problems.

However there is a risk of ingesting internal parasites. This can happen if your dog eats the faeces of unfamiliar, infested dogs or cats or the faeces of wild life such as rabbit deer etc.

If you worm the dogs regularly then the risk lessens slightly,

Though I have had to treat a number of dogs that are severely Intraspecific Coprophagic.

These dogs eat very old faeces or faeces from dogs that are ill from intestinal problems or with very loose stools.

This was making the dogs that were ingesting them very ill and emaciated. Unless you are successful in treating this level of compulsive coprophagia then it could be fatal.

The fecal-oral route can also transmit some rather nasty canine viral diseases.  Hepatitis and canine parvovirus are just two of these serious diseases. Fortunately, vaccinated dogs should be covered for these potentially fatal viruses.

We now have a further concern regarding Coprophagia, H5N1 Bird Flu. A cat has died in Germany from eating an infected bird; therefore this virus has shown it can cross the species. It is also known that HN51 can be transmitted through faeces/stools, so perhaps we should be looking at this problem with renewed urgency.

I would also strongly recommend keeping the dog away from cat faeces because of the risk of organisms such as Toxoplasma gondii which can cause serious and sometimes fatal consequences, including hepatitis, pneumonia, blindness, and severe neurological disorders . The intestinal phase of this nasty disease occurs only in cats (wild as well as domesticated) therefore transmission to dogs is by ingestion of oocysts (in cat faeces) or bradyzoites in some raw or undercooked meat that has not been pre-frozen. Freezing kills off the organisms and makes it safe.
