Is "The dogs are loyal animals" correct?

Why

Meera's meaning is clear in her own head — she wants to say something true about dogs as an entire category, everywhere, always. The word "the", though, does the opposite job of what a general statement needs: it marks something as ONE SPECIFIC, already-identified set, exactly the way it marked "the dog" as one particular dog in Rohit's story. "The dogs are loyal animals" reads as if pointing at a specific known group of dogs — the dogs at this house, the dogs mentioned earlier — not dogs everywhere in general. To make a genuinely general statement about a whole category with a plural noun, English typically drops the article entirely: "Dogs are loyal animals", with no "the" at all, is what actually reads as a broad, universal claim. Test: compare "Cats are curious" (general, about cats everywhere) with "The cats are curious" (about some specific, known cats, maybe the ones next door) — the presence or absence of "the" is precisely what marks that difference. Her brother is right: "the" narrows the statement to specific dogs; a true general statement needs no article at all — "Dogs are loyal animals".
