Dog owners, brace yourselves, it’s puke talk time. And before you grab the paper towels, take a look at the color.

That weird yellow foam? Or maybe it’s green… or even red? Each shade means something totally different about your pup’s health, and a few could mean get to the vet now.

Here’s your quick (and surprisingly helpful) dog vomit color guide with real vet insights on when to wipe it up and when to call for backup.

Dog Vomit Color Chart: What Your Dog’s Vomit Really Means

Here’s the quick chart every dog parent needs. Save it, screenshot it, whatever keeps it handy, because when your pup gets sick, time matters.

Color	What It Usually Means	When to Worry
🟡 Yellow Vomit	Bile from an empty stomach — common in the morning or after skipping meals (bilious vomiting syndrome in dogs)	If it happens daily or with loss of appetite, see your vet.
🟢 Green Vomit	Often from grass-eating or extra bile. A single episode is normal.	Repeated green vomit can signal reflux or diet issues.
⚪ White Vomit / Foam	Saliva + stomach acid; sometimes mild acid reflux or kennel cough. White vomit can also mean parasites, foreign objects, toxic ingestion, or bloat.	If it keeps happening or your dog seems weak, get a vet check.
🟠 Orange Vomit	Bile mixed with partially digested food can appear orange due to stomach acid or certain foods.	If frequent or streaked with red, see your vet.
🟤 Brown Vomit	Could be food — or poop (coprophagia). Smells like coffee grounds? That’s digested blood.	Vet ASAP if dark or gritty.
🔴 Red Vomit	Fresh blood → irritation, ulcers, or toxin ingestion.	Emergency: call your vet immediately.
⚫ Black Vomit	Digested blood from the stomach or intestines.	True emergency — go to an ER clinic now.

Quick Takeaway: Red or Black vomit = emergency. Everything else? Watch, note the color, and read the next sections for context.

The Gross Truth: Dog Regurgitation vs Vomiting

Before you can decode what the colors mean, you need to know what kind of mess you’re looking at.
“Vomit” and “regurgitation” sound the same, but they’re two totally different body moves, and knowing which one your dog’s doing can save you guessing (and a vet bill).

What Is Vomiting?

• Comes from the stomach.
• Usually noisy — you’ll hear heaving, see belly contractions, and smell bile.
• What you’ll notice: partially digested food, yellow or green liquid, maybe drooling or foam.
• Common causes: diet change, eating something gross, toxins, or stomach bugs.

So, what color should dog vomit be? Well, the color of dog vomit will be similar to what they’ve eaten, but will appear digested (think along the lines of adding water to their meal and putting it in a food processor).

There are many possible colors for vomit, from a dog throwing up yellow foam to a green or white appearance. Of course, how well-digested the food appears depends on how long ago they ate.

What Is Regurgitation?

• Comes from the esophagus, not the stomach.
• Happens quietly, often soon after eating — no retching, no drama.
• What you’ll notice: whole pieces of kibble or food shaped like a tube of mush.
• Possible causes: eating too fast, swallowing issues, or certain esophageal disorders.

In contrast, regurgitation occurs when a dog throws up undigested food. Regurgitated food will look very similar in texture and color to what your dog has just eaten, or may take on the form of the stomach or esophagus and appear like a compacted cylinder of food.

Yellow, Green & Orange: The 3 “Mostly Normal” Colors

Not every puddle of puke means panic. Some colors are gross but harmless, especially when they happen just once. Here’s how to read the less-scary shades.

1. Yellow Dog Vomit

This one’s the classic dog throwing up yellow bile moment. It usually happens on an empty stomach, either first thing in the morning or after your dog skips a meal.

That foamy yellow tint comes from bile, the fluid that digests fat. Too much bile sitting in the stomach irritates the lining, leading to what vets call bilious vomiting syndrome.

Here’s what Dr. Baldwin has to say on yellow dog vomit:

Rest assured that this is a ‘normal’ vomit color. Yellow dog vomit normally contains bile, a substance produced by the liver and stored in the gallbladder. A dog throwing up yellow bile typically occurs when their stomach is empty.

Larger amounts of bile in vomit may have a yellow-green appearance. Yellow dog vomit is rarely a cause for concern unless it frequently occurs, although you should consider your dog’s overall health and other symptoms.

A dog frequently throwing up yellow bile is a condition referred to as bilious vomiting syndrome (BVS). This is not a life-threatening condition, but you should speak with your vet. Often, treatment involves giving pups smaller, more frequent meals or a late-night snack.

– Dr. Katherine Baldwin, Veterinarian Contributor to Canine Journal

Quick Tip: Feed smaller, more frequent meals or a late-night snack to keep bile in check.

2. Green Dog Vomit

A green splash often means your dog just ate grass. Many pups nibble grass to trigger vomiting and settle their stomachs. It’s basically canine self-care.

If the vomit looks slimy green without bits of grass, it could be excess bile or reflux instead.

Dr. Baldwin states that:

When it comes to the dog vomit color scale, green isn’t usually a cause for concern. However, if your dog is vomiting excessively or for a prolonged period, then seek veterinary advice.

3. Orange Dog Vomit

This happens when bile mixes with partially digested food, giving an orange tint. A one-off orange vomit isn’t alarming; it’s usually just stomach acid doing its job.

Dr. Baldwin adds:

If your dog’s vomit is an orange color, it could be for a few reasons. While bile is usually a yellow liquid, it can be tinted orange. Orange vomit may be a sign that your dog’s stomach was empty when they were vomiting.

Vomit can also take on the color of food or food coloring that a dog eats. Look at your dog’s food and what they’ve recently eaten to determine if your dog’s vomit is an orange color because of food dye.

See your vet if it keeps happening or if you notice red streaks (possible blood).

White, Brown, Red, & Black: The 4-Shaded Danger Zone

These shades deserve extra attention. Brown and white can be normal or, in certain cases, point to something more serious than a stomach upset. Especially if the color is dark, persistent, or has a foul smell. Red and black? Immediate vet territory. Let’s take a look:

1. White or Pale Vomit

White or pale vomit may include partially digested food, especially if your dog hasn’t eaten for several hours. But white foam—saliva and stomach liquid only—can signal more serious issues, such as:

• Gastrointestinal infection or parasite
• Foreign object ingestion
• Pancreatitis
• Exposure to a toxin or chemical

Dr. Baldwin warns:

If your dog is trying to vomit but cannot, or they’re repeatedly bringing up small amounts of white foam, this could indicate bloat or more severe gut problems. This could be an emergency, and you should call the nearest open veterinary clinic immediately.

2. Brown Dog Vomit

Brown vomit can be harmless or serious, and it is a common color for dog vomit. If your dog just ate kibble or treats, the color may simply match their food.

As much as we love our furry friends, we must admit some have less than choosy dining habits. Brown vomit might mean your dog has scavenged something unsavory or eaten poo. Eating poo has a name – coprophagia. The clue might be in the smell of the vomit.

Dr. Baldwin explains when brown dog vomit needs more attention:

Dark brown vomit is more concerning. Digested blood may appear dark brown or have the appearance of coffee granules mixed in with the vomit. This could indicate bleeding within your dog’s intestines. If your dog is throwing up brown stuff repeatedly, you should contact your veterinarian.

3. Red Dog Vomit

Red vomit signals fresh blood. A few streaks after heavy retching can come from burst vessels, but any steady or large amount of red indicates a serious problem, such as an ulcer, toxin ingestion, or internal injury.

Dr. Baldwin states:

Red vomit is of concern as it usually means the vomit contains blood. This could be due to bleeding within your dog’s intestines, toxin ingestion, or a problem with your dog’s blood clotting.

If your dog has been vomiting excessively for a short period, the vomit may be streaked with red blood. This could be because small blood vessels in the stomach or esophagus have burst due to the force of vomiting.

Red vomit should be seen as severe on the dog vomit color chart. Contact your veterinarian for urgent advice.

4. Black Dog Vomit

Black or very dark brown vomit can mean digested blood from deeper inside the stomach or intestines.
It often looks like coffee grounds or tar.

Dr. Baldwin advises:

Black vomit can be due to your dog ingesting something of a similar color (such as farm animal poo or mud/dirt). However, black vomit can also indicate digested blood caused by eating toxins or bleeding within the gut. Black vomit shouldn’t be considered normal, and urgent veterinary advice should be sought.

If you’re unsure whether it’s dark food or blood, take a photo and contact your vet or the nearest emergency clinic.

When any vomit looks dark, bloody, or foamy-white, contact a vet immediately. Black and red vomit should always be considered an emergency. Seek in-person veterinary care as soon as possible for your pup if you see black or red vomit.

Texture Talk: Chunky, Liquid, or Foamy?

Sometimes it’s not just the color that matters; the consistency of your dog’s vomit can reveal what’s going on inside their stomach.

No one wants to hang around for long examining their dog’s vomit, but before cleaning up after your canine friend, it’s worth looking at what they’ve vomited.

Here’s what different types of dog vomit tell you about timing and possible causes.

Chunky Vomit

If you can still see chunks of food, your dog probably vomited soon after eating. The food hasn’t had time to digest, so the stomach is reacting to something it didn’t like.

This can happen after eating too quickly, swallowing air, or reacting to a new treat or diet change.

When to worry: if chunky vomit happens often or includes unusual items like fabric, toy parts, or grass clumps — your dog might have ingested something foreign that could cause an intestinal blockage.

Liquid Vomit

Watery vomit or clear liquid often happens when your dog’s stomach is already empty. It can also show up when your dog drinks too much water at once or can’t keep fluids down.

Clear or yellow liquid may be bile or stomach acid.

Watch for: repeated liquid vomiting or signs of dehydration (sunken eyes, dry gums, lethargy). Those are reasons to call your vet.

Foamy Vomit

Foamy vomit looks like bubbly spit or light white froth — it’s saliva and stomach acid mixed together.
This can appear when a dog’s stomach is irritated but empty, such as in mild reflux or an early upset stomach.

However, frequent white foam vomiting can also point to pancreatitis, ingestion of something toxic, or bloat (when the stomach twists and traps gas).

Emergency rule: if your dog is retching or trying to vomit but nothing comes out, or only small amounts of foam appear, go to the nearest open veterinary clinic immediately.

When to Worry: 5 Signs It’s Vet Time

Most of the time, a single round of dog vomit isn’t a big deal. But there are moments when “wait and see” turns into “call your vet now.” Here are five clear warning signs every dog parent should know.

1. The Vomiting Doesn’t Stop

If your dog keeps throwing up more than twice in a day or can’t hold down water, that’s a red flag. Repeated vomiting can cause dehydration quickly and often means something deeper than a simple upset stomach.

2. There’s Blood or Coffee-Ground Material

Red or black specks in vomit point to blood somewhere in the digestive tract. Coffee-ground texture means the blood has been partially digested. Either way, it’s time for an urgent vet visit.

3. Your Dog Is Lethargic or Refuses Food

A dog that vomits once but then acts normal is usually fine. But a dog that’s weak, tired, or not eating may be fighting infection, inflammation, or something more serious like pancreatitis.

4. Their Belly Looks Bloated, or They’re Trying to Vomit But Can’t

This can signal bloat (gastric dilatation-volvulus), a life-threatening emergency where the stomach twists and traps air. If you see this, a distended belly, pacing, whining, or retching without results, go to an emergency vet clinic immediately.

5. You Spot Foreign Objects or Toxins

If you find pieces of toys, fabric, rocks, or plastic in the vomit, or suspect your dog swallowed something toxic (chocolate, xylitol, medication, plants), skip the guesswork and get professional help right away.

Dr. Baldwin has this to say about foreign bodies in dog vomit:

Foreign objects being thrown up, such as toys, rocks, or fabric material, is a way for your dog’s body to get rid of items that aren’t meant for digestion. Ingestion of foreign objects is nearly always of concern as it may mean your dog has eaten or chewed things that are dangerous to them.

There is a risk that they can’t vomit all of the foreign material they’ve ingested. If any gets stuck, it can cause an obstruction. This could result in a severe medical emergency.

When in doubt, take a photo of the vomit and call your vet, as a description helps them triage faster.

What Another Veterinarian Says About Dog Vomit Colors

I also spoke with veterinarian Dr. Rebecca MacMillan, BVetMed, BSAVA, PGCertSAM, MRCVS, a companion animal veterinarian in Gloucester, United Kingdom, who offers more guidance on dog vomit color and when to be worried.

“The color of a dog’s vomit can sometimes be an indication of the severity of their condition. One of the main things to look out for is whether there is any blood present. In my experience, hemorrhagic (bloody) vomit can be pretty serious and requires immediate medical intervention.

Dr. MacMillan also addresses clear vomit, “Another vomit color to look out for is clear fluid, which may mean your dog is unable to hold water down. This could put them at risk of dehydration. I have seen this in dogs with severe nausea, but also foreign body obstructions, which are an emergency.

“If your dog is suffering from a mild stomach upset and is still bright, with no evidence of any blood, then bland food for a few days should help things resolve.

However, if your dog is lethargic, struggling to hold down fluids, or they are bringing up blood, you should always seek veterinary help sooner rather than later,” says Dr. MacMillan.

Did You Know Pet Insurance Can Cover Illness?

Seeing your dog unwell can be very upsetting. If it only happens once in a while, it’s unlikely to be anything to worry about.

Some dogs have a reputation for eating just about anything, so vomiting can be a useful protective mechanism. However, the next time your pooch is feeling sick, pause to consider what they’ve vomited – it may help you identify what is wrong and indicate when to seek medical attention for your pet sooner.

If you’re signed up for pet insurance, many of the expenses may be eligible for coverage, saving you a hefty vet bill. Things like vomiting, diagnostic testing, and more can be eligible for coverage through pet insurance if they’re not associated with a preexisting condition.

FAQs About Types of Dog Vomit

Got more questions about dog vomit colors, types of dog vomit, or what your pup’s symptoms might mean? You’re not alone, and these are some of the most common things dog parents ask. If you don’t see your question here, drop it in the comments below and we’ll help find an answer.

What Color Dog Vomit Is Most Concerning?

The most dangerous colors are red, black, or very dark brown, since they often indicate blood in the vomit. Black or “coffee-ground” vomit can mean internal bleeding, while bright red vomit shows active bleeding higher in the digestive tract. White foam can also indicate serious health problems.

If you ever see any of these, call your vet or an emergency clinic immediately.

Why Is My Dog Vomiting Yellow Bile?

Yellow dog vomit usually contains bile and often happens when your dog’s stomach is empty, for example, early morning or after skipping a meal. It’s common in bilious vomiting syndrome and can improve with smaller, more frequent meals or a bedtime snack.

If it happens often, talk to your vet about diet adjustments or possible reflux issues.

What Does It Mean If My Dog Throws Up White Foam?

White foamy vomit is usually saliva and stomach acid mixed together. It can happen with mild stomach irritation, but if your dog is repeatedly vomiting foam or struggling to bring something up, it could be a sign of bloat, pancreatitis, or toxin ingestion, all medical emergencies that need immediate care.

Why Is My Dog’s Vomit Green Or Orange?

Green vomit often happens after eating grass or when bile builds up in the stomach. Orange vomit appears when bile mixes with partially digested food or orange-tinted ingredients like carrots or pumpkin.
Occasional green or orange vomit isn’t alarming, but repeated episodes may point to reflux or digestive irritation.

How Do I Know If My Dog Is Vomiting Or Regurgitating?

• Vomiting is active; you’ll see heaving, retching, and partially digested food.
• Regurgitation is passive; food just falls out of your dog’s mouth without effort, usually still whole.

Vomiting points to stomach or intestinal problems, while regurgitation involves the esophagus. Your vet can help identify which it is.

When Should I Take My Dog To The Vet For Vomiting?

Call your vet if vomiting happens more than twice in a day, contains blood, looks black or coffee-ground-like, or if your dog is weak, refusing food, or bloated.

Persistent vomiting can cause dehydration and may signal an underlying illness that needs professional treatment.
