Dogs eat poop, it's a behaviour called coprophagia, which happens for a variety of reasons, including instinct, habit, and even medical issues.
However grim, it's often a normal behaviour, especially in puppies, but can also be a sign of underlying health problems or psychological issues.

Here's why it might happen:
1. Instinct and Habit:
Instinctual behaviour:
Dogs, like wolves, may have an instinct to keep their living area clean by consuming faeces, especially from puppies.
Habit:
Dogs may develop coprophagia as a learned behaviour, especially if they were previously rewarded (even unintentionally) for eating poop.
Nutritional deficiencies:
If a dog's diet is lacking certain nutrients, they might eat poop to try and supplement what's missing.
Inadequate digestion:
Some dogs might not properly absorb nutrients from their food and may try to get them from faeces.
2. Medical Conditions:
Parasites:
Intestinal parasites can affect nutrient absorption, leading a dog to eat poop.
Medical conditions:
Certain diseases like Cushing's disease, thyroid issues, or malabsorption disorders can cause coprophagia.
3. Psychological Factors:
Boredom, stress, or anxiety: Dogs may eat poop to cope with these emotions or seek attention.
Attention seeking: Some dogs might eat poop to get a reaction from their owners.
Isolation or confinement: Dogs kept alone or in small spaces may eat poop out of boredom or stress.
Fear of punishment: Dogs may eat poop to hide evidence of accidents, especially if they were punished for them.
4. Other Factors:
Nursing mothers: Female dogs may eat the poop of their puppies to keep the den clean.
Curiosity: Puppies, like human toddlers, may explore by putting things in their mouths,
including faeces.
Taste: Some dogs simply seem to enjoy the taste or smell of certain types of poop.
What to do:
Consult your vet:
If coprophagia is a sudden change in behaviour or if your dog is exhibiting other symptoms, it's important to rule out medical causes.
Its also super important to worm with a wormer that includes tapeworm treatment, speak to your vet for the best frequency and product.
Address psychological issues:
Provide more mental and physical stimulation, enrichment toys, and address any anxiety or stress.
Improve diet:
Ensure your dog is getting a balanced and appropriate diet.
Manage the environment:
Keep your yard clean, supervise your dog, and discourage them from eating poop.
