Nobody in this poem claims the dog, and nobody drives it off. It is the neighbourhood stray, fed a little and left alone, and Gomez sketches this half-arrangement between animal and people so lightly that the last line catches us off guard. Having established that the dog is "not ours," the poem turns the sentence around: "We are that dog's." The central idea is that belonging does not depend on ownership. The dog keeps its freedom, and the people become the ones who are held, by habit, by small kindnesses, by the pull of an animal that asks for nothing.
The voice is casual from the start. "You know" is how people talk across a fence, and "folks" is a homely word. The speaker seems to be pointing out a dog we have all seen. That pointing is built into the grammar: "that" appears six times, in "That stray dog," "That one," "that dog tramps," and so on, each time like a finger toward the street. The title, "Canis," is the Latin word for dog. It sounds formal and almost taxonomic, which makes a nice contrast with the loose speech of the poem. The label belongs in a textbook, but the animal it names won't be filed under "pet" or "wild."
The second long stanza is where the language does its most interesting work. The first clause, "On occasion tossed a scrap," has no subject and no helping verb. The kindnesses just happen, and the people who perform them have disappeared from the sentence. "Water left / in bowls to lap" works the same way, with a bowl set down by no one in particular. The effect is that human generosity looks casual and slightly careless, while the dog is the only character with a verb of its own: it "tramps." That word suggests both a steady, padding walk and the old image of the vagrant. "Lap" does two jobs as well. It is how a dog drinks, but it also echoes "lap dog," the very thing this animal refuses to be. The short *a* sounds in "scrap," "lap," "tramps" and "that" give the lines a clipped, trotting beat.
The line breaks are doing quiet work too. In the first stanza, "enough liking to / it never goes feral," the line ends on "to," so for a moment we seem to be reading "liking to it," and the sentence only settles into sense on the next line. The phrase also measures affection very carefully: people like the dog *enough*, no more, and that exact amount is what keeps it from going wild. Later, "the domestic yet" ends a line on the word "yet," which leaves the dog hovering at the edge of the house before the next line confirms it has "without any urge to join."
There is no rhyme and no regular metre. The poem is free verse, and its shape does the persuading. The stanzas thin out after the long one, going from five lines to two, then one, then one, as if the poem were shedding words the way the dog sheds the need for a home. "That dog belongs / by not belonging" is the hinge. The paradox is built from one word repeated and negated, and the line break lets "belongs" stand alone for a beat as a plain claim before the second line takes it back. Then comes the flat, almost stubborn "That dog is not ours." Until this point the people have been "folks" and "you," observers at a safe distance. The pronoun "we" arrives only in the final line, and it arrives as a possession: "that dog's." The sentence stops without saying what we are the dog's *of*. Its people? Its neighbourhood? Its property? Leaving the noun out lets the ownership feel total and vague at once.
The poem is significant because it takes a very ordinary sight and quietly overturns an assumption about who holds power in a relationship. You could read the dog as literal, or, as an inference from the way the poem speaks of belonging, as a stand-in for anyone who lives at the edge of a community, tolerated, helped a little, and never fully absorbed. Either way, the poem suggests that the one who needs nothing from us may be the one we cannot walk away from.
