What is coprophagia?

Coprophagia is the ingestion of faeces by an animal – whether it be their own or that of another animal. Research shows that up to 23% of dogs may eat faeces, with 16% being regular offenders. Yuck!

Coprophagia can also increase the risk of pathogen transmission (some of which may be zoonotic) and rarely, result in medication toxicity.

Ultimately, this behaviour is unpleasant for many owners, and in severe circumstances may even be a reason for them to consider rehoming or euthanasia.


In the majority of cases, coprophagia is an abnormal and undesirable behaviour with a number of potential medical or behavioural causes. Whilst it is important to identify and treat underlying medical causes, most cases are behaviour-associated and therefore require behavioural modification training to help resolve the behaviour.

How can COPRONIL help?

  • COPRONIL makes faeces unpalatable to an animal, giving the owner an opportunity to break the cycle by modifying behaviour.

  • COPRONIL also provides a comprehensive B vitamin source, as deficiencies in B vitamins may contribute to coprophagia.
