Dave Bonta's poem opens with a question that sounds like a punchline: "Do I smell of dalmatian?" Nothing is explained. We land in the middle of a mind that has already jumped to a conclusion, and we have to piece the situation together. The speaker sees dark spots everywhere, and is riding in a car with their head out of the window, trying to reason about the spots the way a dog might. That is the "Dog Logic" of the title: thinking by association and by sensation, not by diagnosis. The poem never says what the spots are, but spots that stay put in your vision and slide away when you look straight at them are a familiar kind of visual nuisance.
The phrase "these damned spots" may faintly echo Lady Macbeth's "Out, damned spot!", though the poem doesn't push the connection. It does give the spots a stubbornness, as if they were a stain that won't wash out. The next image is stranger: "I should stop / watering them with tears." Watering turns the spots into something that grows, fed by the speaker's own crying. The wind explains the tears, since anyone who has faced a moving car's airstream knows how it makes the eyes stream. But the verb leaves room for another kind of weeping, and the poem doesn't choose between them. The comedy stays on the surface, and the unease underneath is only hinted at.
The central joke is a small piece of faulty reasoning. If a dalmatian runs fast enough, its spots should blur into stripes, so a speeding speaker should see stripes. "Surely at this speed / I should be seeing stripes?" The "Surely" is perfectly serious, and that deadpan is what makes the line funny. Then comes the hinge, "But no." The spots are not out in the world, where speed could smear them. They are in the eye, and they travel with it. They are "little blanks," absences and not marks, and they stay "sharply delineated" however fast the landscape rushes past.
The form carries this mood of restless, wind-blown thinking. It is a single block of sixteen lines with no stanza breaks and no rhyme, in short lines that break in the middle of phrases: "ever going / to shrink," "putting my head out / the window." The reader is pushed from line to line without a chance to settle, much like the passenger with a face full of air. The ampersands, twice in place of "and," keep the tone quick and casual. The sentences have a clear shape too: three questions in a row, then the long answer that begins with "But no," then a flat fragment to finish. There is also a small accident of sound: "spots" and "stop" are made of the same letters, so the thing the speaker wants to end is quietly mirrored in the command to end it.
The ending changes the picture. To describe how sharp the spots are, the speaker reaches for a simile from outside the dog world: "a stray cat slinking in / to drink milk." The short, slippery vowels of "slinking in to drink milk" make the line itself move like a cat. Then the colon and a startlingly formal word: "lapidary." It usually describes something cut or engraved with stone-carver's precision, and it fits the crisp edges of the spots. It also hides "lap" inside it, which is exactly what a cat does with milk, so the learned word and the animal image share a sound. The last line, "Impossible to catch," finishes the dog logic. A dog's instinct is to chase the cat, and the speaker's eyes are always chasing spots that dart away the moment they are looked at.
What makes the poem worth reading is how much it does in sixteen lines. A minor, irritating experience becomes a small comedy of reasoning, and the dog's open-faced attention to the wind and the world gives the speaker a way to look at the problem. The poem is also lapidary in its own right, compact and hard-edged, with a hint of sadness under the humour. Like the spots, that sadness is there, sharply outlined, and can't quite be caught.
