Why Dogs Eating Dirty

Why Dogs Eating Dirty

Coprophagia (the ingestion of excrement) is widespread in many animals, not just dogs. We do not know very well why dogs eat disgusting and dirty feces. Some have a genetic propensity for coprophagia, and in this case, it is around the age of 4 to 10 months that this behavior manifests itself. The coprophagia generally stops when the animal reaches the age of one year.

There are many reasons why dogs like to eat cat poop and litter, but no one is really sure of the reasons for this behavior. Sometimes, the problem is medical, especially in the case of pancreatic insufficiency or malabsorption syndrome, two conditions that compromise the digestion of food.

Dogs communicate through their mouths. They love to carry sticks and they love to chew toys or bones. Dogs also like things that smell and feces are obviously in this category. Strange as it may seem, your dog probably eats droppings to examine something that interests him.

Most, puppies eat their own droppings when they learn to clean. This happens because they are still unsure where to defecate or not. Afraid of having made a mistake, puppies will “destroy all evidence”.

This behavior can also happen with adult dogs that stay locked inside. They often eat the stools of their puppies by cleaning them at a young age.

Some dogs eat their excrement to recover unabsorbed nutrients. For example, dogs that receive foods high in starch and carbohydrates, and low in fat and fiber, are more likely to eat their feces, as are dogs that receive mostly dry or low-quality food.

Cat’s diet is rich in protein. So cat’s feces can attract your dog. You must imperatively and quickly discourage this behavior because cat litter can be dangerous to your dog.


Thus, dogs that eat the feces of other animals are unlikely to lose this habit unless they are prevented from doing so. Coprophagy is very difficult to stop:

  • You must first clean the dog’s environment without delay before he eats his excrement.
  • Prevent boredom by increasing your dog’s activity.
  • Also be sure to provide a balanced diet, very digestible and that meets his needs.
  • Adopting foods that are high in fat, fiber and protein and low in carbohydrates may be effective.
  • Some “tricks” work well, like sprinkling food with a tasteless meat tenderizer or commercial product or giving the dog some canned pumpkin.

In any case, if your dog is coprophagous, consult your veterinarian.

Why Bother Recycling?

Why Bother Recycling?

Organic waste is all the waste that can be degraded by micro-organisms. We find there:

Animal products: blood, meat, milk, …
Vegetables and food leftovers
Gardening waste: cut grass, remains of pruning …
Sludge from the wastewater recycling process
Why recycle organic waste?


Organic waste constitutes 30% of the waste rejected by the average household, as well as most of the waste of the Agrifood Industry. These wastes are therefore present in large quantities, and recycling them makes it possible to reduce the volumes treated by the conventional incinerator.

In addition, these wastes can pose several problems if they are poorly managed:

How does it work?

The green waste is sent to special centers where a quick manual sorting tries to remove the non-degradable elements such as stones, glass, etc. From there, green waste can follow two distinct paths: anaerobic digestion or industrial composting.

Industrial composting

The waste is crushed, mixed with chips to ensure good ventilation and finally stacked in the open air in the form of huge piles. They are then left there for six to ten months. Every month, a construction machine is used to return the piles (composting needs aeration). Bacteria, worms, and fungi will colonize the mass of biodegradable waste and feed on the nitrogen and carbon present. Such biological activity can raise the temperature in the center of the pile up a bunch.

An example of industrial composting

The rainwater that falls on these mountains of decomposing waste is reprocessed (see treatment of wastewater) because they come out too loaded with nitrogen.
At the end of the process, the compost looks like a black earth, heavy and granular. This material is meant to obtain a perfectly homogeneous material that will be resold.

Anaerobic digestion

Beautifully called “anaerobic digestion” by professionals, this process is less common than composting. Unlike the latter which requires dry elements to avoid rotting, methanation works perfectly with liquids or very wet, poor in structuring elements.
