It depends on the amount and source — but bleeding that is heavy, spurting, or won't stop is an emergency. Apply firm pressure with a clean cloth and get to a vet. **Bleeding that doesn't slow after about 5 minutes of steady pressure, blood that spurts, a large wound, or bleeding from the nose, mouth, or rear end** needs emergency care now. Unexplained bleeding or bruising in several places can signal a poisoning (like rat bait) or a clotting problem and is also urgent. A small nick that stops quickly can usually be watched.
## First aid for bleeding 1. Apply firm, direct pressure with a clean cloth or gauze over the wound. 2. Hold it steadily for at least 5 minutes without lifting to peek — checking too soon disrupts the clot. 3. Add more layers on top if blood soaks through; don't remove the soaked ones. 4. Elevate the area if it's a limb and you can do so safely. 5. Get to the vet, keeping pressure on during the trip if possible.
Avoid tourniquets unless a professional directs you — they can cause harm if used incorrectly.
## When it's a go-now emergency - Bleeding that won't stop after ~5 minutes of firm pressure, or that spurts. - A large, deep, or gaping wound, or one from a car accident, bite, or major trauma. - Blood from the nose, mouth, rear, or in urine or stool without an obvious small cut. - Bruising or bleeding in several places at once — possible poisoning or clotting disorder. - Pale gums, weakness, or collapse with the bleeding — signs of significant blood loss.
## When brief monitoring is okay A minor scrape or a small nicked nail that stops bleeding within a few minutes and leaves your dog comfortable can usually be cleaned and watched. If it reopens, won't stop, or looks deep, get it seen.

Common questions
How long should I hold pressure before deciding it's an emergency?
Apply firm, uninterrupted pressure for at least 5 minutes. If the bleeding hasn't clearly slowed by then, or it's heavy or spurting, treat it as an emergency and go to the vet while maintaining pressure.
My dog is bleeding a little from a small cut — do we need the vet?
A minor cut that stops quickly can usually be cleaned and monitored. See a vet if it's deep, won't stop, reopens, becomes swollen or infected, or was caused by a bite.
My dog is bruising in several spots with no injury — is that serious?
Yes. Unexplained bruising or bleeding in multiple places can indicate a clotting problem or poisoning such as rat bait, which is an emergency. Go to a vet immediately.
