What Does the Quran Say About Dogs — and How Judaism and Christianity Compare

Dogs appear in the Hebrew Bible in both neutral and negative registers. In Exodus 11:7, the dog's silence during the Exodus is framed as a divine sign of distinction between Israel and Egypt Exodus 11:7, suggesting the animal was familiar enough to Israelite life that its behavior carried symbolic weight. Dogs were clearly present in everyday ancient Israelite society as working animals.

The more restrictive passage comes from Deuteronomy 23:18, which prohibits bringing 'the price of a dog' into the Temple as a vow offering Deuteronomy 23:18. Rabbinic interpretation, notably in the Mishnah tractate Temurah, understood 'price of a dog' to refer to barter involving dogs used in trade — not a condemnation of the animal itself. Dogs weren't considered ritually impure in the same categorical way as, say, pork; they simply had no place in the sacrificial economy.

Medieval scholar Maimonides (12th century) noted that the Deuteronomy prohibition was economic and cultic in nature, not a blanket moral judgment on dogs. Working dogs guarding flocks appear without censure throughout biblical narrative, and the Talmud even discusses practical rules about keeping dogs safely in urban settings, reflecting a pragmatic rather than hostile attitude.

The New Testament's most direct reference to dogs is metaphorical rather than legal. In Matthew 7:6, Jesus warns his followers not to give holy things to dogs or cast pearls before swine Matthew 7:6. Most mainstream Christian commentators — including John Calvin in his 16th-century Commentary on the Gospels — read 'dogs' here as a figure of speech for people who are hostile or indifferent to sacred truth, not as a zoological statement about the animals themselves.

Christianity inherited the Hebrew Bible's ambivalence but didn't develop a formal purity code around dogs the way classical Islamic jurisprudence did. Dogs aren't listed among forbidden foods in any New Testament text, and the Mosaic dietary laws were widely understood by early Christian theologians — Paul, then Augustine — to have been fulfilled or superseded in Christ. There's no Christian canonical prohibition on touching or keeping dogs.

In practice, Christian cultures across history have kept dogs as companions and working animals without theological controversy. The metaphorical use in Matthew 7:6 remains the passage most often cited in sermons, functioning as a pastoral caution about discernment rather than any statement about canine ritual status Matthew 7:6.

The Quran itself is notably sparse on dogs. The key dietary verse, Quran 6:145, lists the prohibited foods as carrion, flowing blood, and pork — dogs aren't mentioned Quran 6:145. This means the Quran does not explicitly forbid eating dog meat in the same direct way it forbids pork, though classical scholars like al-Nawawi (13th century) derived a prohibition from hadith literature rather than Quranic text alone. The Quran's silence on dogs is itself theologically significant to some modern Muslim scholars who argue the animal has been over-restricted by tradition beyond what scripture demands.

One Quranic passage that does feature a dog positively is Surah 18 (Al-Kahf), the story of the Companions of the Cave, where a dog faithfully guards the sleeping believers — a detail the Quran mentions without any negative connotation. This is frequently cited by scholars like Javed Ahmad Ghamidi (contemporary Pakistani theologian) as evidence that the Quran does not treat dogs as inherently impure or evil.

The dominant jurisprudential position across the four Sunni schools — Hanafi, Maliki, Shafi'i, and Hanbali — holds that dog saliva is ritually impure (najis), requiring special purification of any vessel a dog has licked. This ruling derives from hadith collections, not from any explicit Quranic verse. The Maliki school is notably more lenient, permitting hunting dogs and their contact more broadly. It's worth acknowledging real disagreement here: contemporary Muslim scholars continue to debate whether these hadith-based restrictions should be read strictly or contextually.

Quran 6:145 does establish the principle that what isn't explicitly prohibited by revelation isn't necessarily forbidden Quran 6:145, a hermeneutical point some modern scholars use to argue for a more permissive attitude toward dogs than classical fiqh has traditionally allowed.
