Reference excerpt

To see a man about a dog, horse or duck is an idiom, especially British English, of apology for one's imminent departure or absence, generally to euphemistically conceal one's true purpose, such as going to use the toilet or going to buy an alcoholic drink. The original non-facetious meaning was probably to place or settle a bet on a race, perhaps accompanied by a wink. In the UK the phrase is generally used nowadays as a polite way of saying, "I am going out [or "have been out"], but don't ask where", often with the facetious implication that you are about to be, or have been, up to no good. In the Southern US, going to see a man about a dog signifies that one is going to urinate, while going to see a man about a horse signifies that one is going to defecate, and thus may be away a bit longer.

Historical usage The earliest confirmed publication is the 1866 Dion Boucicault play Flying Scud, in which a character knowingly breezes past a difficult situation saying, "Excuse me Mr. Quail, I can't stop; I've got to see a man about a dog." Time magazine observed that the phrase was the play's "claim to fame". In Newcastle upon Tyne, Newcastle Brown Ale commonly gained the nickname of "Dog" from the frequent use of the phrase to describe going to the pub. During Prohibition in the United States, the phrase was most commonly used in relation to the consumption or purchase of alcoholic beverages. The phrase entered into American usage when Cary Grant used it to escape an awkward social situation in the 1938 film Bringing Up Baby, an iconic screwball comedy.

Worked examples

Example 1 — a first encounter with See a man about a dog

Start with the simplest possible case. Write down what See a man about a dog claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to See a man about a dog before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about See a man about a dog ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of See a man about a dog

In research: See a man about a dog appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses See a man about a dog in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: See a man about a dog is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1860s neologisms, 1860s quotations, British English idioms, so understanding it makes those chapters shorter.
