Forum Animal Health has launched the UK's first granular solution for wet and dry food in a bid to tackle coprophagia ' the undesirable and potentially dangerous problem of animals particularly dogs and puppies eating their own faeces through Copro-nil curbing the animal's behavior as well as inducing a healthy digestion system to help stop the problem.

The benefits of Copro- Nil are: making animal's faeces highly unpalatable which results in the animal finding eating faeces unappealin, counters potential dietary deficiencies such as low folate and B12 which are thought to contribute to coprophagia, brings normal gut function and intrinsic vitamin production that may counteract the condition.

Forum is advising that treating coprophagia is approached from several angles- first removing faeces to prevent access by the animal diversion tactics and seeking specialised training however these can be expensive and time-consuming.

There are multiple factors contributing to the desire for an animal to eat its own (or others') faeces- Vitamin deficiency curiosity boredom natural instinct excess protein levels in the faces and habit all interact to stimulate an animal to consume excrement and Over-feeding animals can also encourage coprophagy as undigested food is left in the faeces.

I bought Copro nil for my dogs. One of whom has a bad habit of eating poop. Since starting them on this the problem has reduced, not stopped, but it's early days yet just 2 weeks. This product gets good reviews but is usually very expensive. Pet Drugs Online sell at a more affordable cost.


Seems to work, but not sure how much longer it needs to be given for to break the habit
