Question 1

Why does my dog eat poo?

Accepted Answer

The behaviour is called **coprophagia**, it is common, and it is usually normal rather than a sign of illness — though a few causes are worth ruling out.

**How common.** Survey research suggests a substantial minority of dogs do it at least occasionally, with a smaller proportion doing it regularly. Most affected dogs are otherwise healthy and well fed.

**The likely explanations:**

**Ancestral behaviour.** The most widely supported hypothesis, from research by Hart and colleagues, is that it evolved as a **parasite-avoidance strategy**. Faeces left in a den site become infectious after a few days as parasite eggs mature, so consuming fresh droppings before that window removes the hazard. Consistent with this, dogs strongly prefer **fresh** faeces — typically less than two days old.

**Maternal behaviour.** Mothers clean puppies by consuming their waste, keeping the den clean and undetectable. Puppies commonly copy it, and most grow out of it.

**Exploration and learning** in young dogs.

**Attention.** If it reliably produces a dramatic human reaction, that can reinforce it.

**Stress, confinement or boredom.** Associated with restrictive environments.

**Learned from another dog** in the household.

**Medical causes worth excluding**, though these are less common than assumed: parasites, malabsorption conditions, diabetes, thyroid problems, and some medications increasing appetite. **Sudden onset in an adult dog that never did it before** warrants a vet check.

**A note on nutrition:** the popular claim that it indicates dietary deficiency is not well supported, and studies have found no consistent link with diet quality.

**What actually helps:**

**Prompt removal.** The most effective measure by far — clean up immediately, and supervise on walks.

**A reliable "leave it"** and a strong recall.

**Do not punish**, which can teach the dog to consume the evidence faster.

**Deterrent food additives** have weak evidence.

**Cat litter trays** should be inaccessible, since this is a common source.

Question 2

Why does my dog eat grass?

Accepted Answer

Grass eating is common and, in most dogs, entirely normal. Surveys of owners consistently find that a large majority of dogs do it at least occasionally, and that the majority show no signs of

Question 3

What does the evidence actually say about raw feeding pets?

Accepted Answer

The claimed benefits are largely unsupported by controlled evidence, while the risks — particularly microbiological — are well documented. That is the honest summary, and it is more one-sided than

Question 4

Why does my dog roll in disgusting things?

Accepted Answer

Nobody knows for certain, which is unusual for such a common behaviour. Several explanations are proposed, and the evidence for all of them is thinner than the confidence with which they are

Question 5

Why do dogs get the zoomies?

Accepted Answer

The behaviour has a proper name — Frenetic Random Activity Periods (FRAPs) — and it is a normal, healthy release of built-up energy or arousal. What it looks like: a sudden burst of running in tight

Question 6

What is a zoonosis, and which ones should pet owners know about?

Accepted Answer

A disease that can pass between animals and humans — and while the risk from well-cared-for pets is low, a small number are worth knowing about because the precautions are simple and the consequences

Question 7

What are the best practices for feeding my dog?

Accepted Answer

Feeding a dog properly involves choosing high-quality food, establishing a feeding schedule, measuring portions, providing fresh water, and avoiding harmful human foods.
