Your dog just threw up on the living room rug. Now you wonder what went wrong. Vomiting happens to dogs now and then. But it can point to bigger problems. This guide covers the main reasons dogs vomit. It explains different types of vomit. You will learn home steps to take. And you will know when to call the vet. Use our pet symptom checker to track other signs too.
What Is Vomiting in Dogs?
Vomiting means your dog forces out stomach contents. It often comes with belly heaves. The dog looks sick first. Food comes back up part-digested. It may have bile or mucus. This differs from regurgitation. That is when undigested food just comes up easy. No effort needed. Regurgitation happens right after eating. Vomiting can strike hours later.
Dogs vomit to clear bad stuff from the gut. A one-time event might not worry you. But keep watch. If it repeats, check deeper. Puppies and old dogs face more risks. Their bodies handle less.
Common Causes of Dog Vomiting
Many things make dogs throw up. Most tie to what they eat or health issues. Here are the top ones.
- Diet problems: Dogs eat too fast. Or they grab trash, grass, or people food. This upsets the stomach quick. Check if your dog scarfed down dinner.
- Food changes: Switch kibble too soon? That can cause upset. Go slow over a week.
- Infections: Viruses like parvovirus hit hard. Bacteria or parasites from dirty water add trouble. Pups need shots to fight these.
- Toxins: Chocolate, grapes, or cleaners harm dogs. They lead to fast vomiting. See our pet food safety checker for safe treats.
- Gut blockages: Swallowed toys or bones clog things. Pain follows.
- Other illnesses: Pancreatitis from fatty foods. Kidney or liver issues in older dogs. Heatstroke in summer. Even meds can trigger it.

Types of Dog Vomit and What They Tell You
The look of vomit gives clues. Color and texture matter. Note what you see. It helps the vet later.
Yellow or Green Vomit
This often means bile. It builds up when the stomach sits empty. Common overnight. Or after grass munching. One time? Let it pass. But if it keeps up, check for gut upset.
White Foam or Frothy Vomit
Foam points to too much acid. Or an empty belly. It can signal reflux. Watch if your dog acts off. In rare cases, it ties to bloat. That’s an emergency.
Undigested Food
Food looks whole? Maybe the dog ate too soon after the last meal. Or motion sickness from car rides. If it happens often, test for slow gut movement.
Bloody or Dark Vomit
Red streaks mean fresh blood. Dark like coffee grounds? Digested blood. Both scream vet now. Could be ulcers or clotting problems.
Other Colors
Brown might be old food or poop smell. Slimy or moldy? Think parasites or bad eats.
People often ask: “Why is my dog throwing up yellow?” Or “What about white foam?” These signs match empty stomach woes. For more on shakes with vomit, see why is my dog shaking.
When to Worry About Dog Vomiting
Not all vomits need a rush to the vet. But some do. Act fast if you see these.
- Vomits two or more times in a day.
- Goes on for over 24 hours.
- Dog seems weak, won’t eat, or has diarrhea.
- Belly hurts or looks bloated.
- Blood, foam, or odd colors show up.
- Puppy, senior, or sick dog in the mix.
If your dog ate something bad, call poison control. ASPCA hotline: (888) 426-4435. Dehydration hits quick. Pinch the skin on the neck. If it stays tented, get help.
Users search: “How long can my dog go without eating after vomiting?” Keep water down in small sips. No food for 12 hours. Then try bland stuff.

Home Care for Your Vomiting Dog
For mild cases, help at home first. But stop if it worsens.
- Withhold food: Skip meals for 12-24 hours. Let the gut rest.
- Water in bits: Offer ice cubes or small amounts. Stops more throwing up.
- Bland diet next: Boil chicken and rice. No fat or spice. Feed small portions four times a day. Plain pumpkin helps too.
- Rest up: Keep your dog calm. No walks till better.
Check safe foods with our pet food safety checker. Avoid fatty scraps that cause pancreatitis.
If pain lingers, talk to the vet about options.
When to See a Vet for Dog Vomiting
Don’t wait if signs point to trouble. Go to the vet or ER right away for blood, bloat, or toxin doubt. They will check history. Run tests like blood work or X-rays. Treatment might mean fluids, meds, or surgery.
Early care saves lives. Parvo in pups needs quick shots. For ongoing issues, ask about allergies.
