Dog vomiting is one of the most common issues pet parents face but also one of the most confusing. Sometimes it’s mild and harmless (like eating too fast), and other times it signals something serious that needs immediate attention.

This guide explains why dogs vomit, what the colour of vomit means, early warning symptoms, and safe home-care tips you can use before consulting a qualified animal care professional.

What Is Dog Vomiting?

Dog vomiting is the forceful expulsion of food or fluid from the stomach, usually caused by irritation, infection, food issues, or underlying health conditions. It is different from regurgitation, which is passive and happens without effort.

What are the most common causes of dog vomiting?

Vomiting in dogs can happen due to simple stomach upset or more serious health issues. Here are the most common reasons:

1. Eating too fast

Fast eaters often vomit undigested food shortly after meals, one of the biggest causes of dog vomiting after eating.

2. Sudden diet changes

Feeding new food suddenly can upset the stomach.

3. Spoiled or contaminated food

Dogs may vomit if they eat waste, leftovers, or expired food.

4. Eating grass or foreign objects

Grass, plastic, cloth, toys → irritation → vomiting.

5. Acid reflux / empty stomach

Often causes dog vomiting white foam early in the morning.

6. Bilious vomiting syndrome

Produces yellow foam dog vomit (due to bile).

7. Food allergies

Common if vomiting occurs after specific foods.

8. Motion sickness

Happens in puppies and anxious dogs.

9. Infections or parasites

Tick-borne diseases, stomach infections, or worms may cause vomiting.

10. Serious emergencies

• Blood (dog vomiting blood)
• Coffee-ground like vomit
• Continuous vomiting for hours
• Inability to keep water down

What does the colour of dog vomit mean?

Colour often gives clues to the cause.

• White foam: Often acid reflux, empty stomach, indigestion.
• Yellow foam: Bile reflux, skipped meals, long gaps between meals.
• Clear liquid: Stomach water, mild irritation.
• Undigested food: Eating too fast or early regurgitation.
• Brown or coffee-ground: Possible digested blood → needs urgent professional attention.
• Bright red blood: Active bleeding → emergency.

Home Care Tips for Dog Vomiting

If vomiting is mild and your dog is still alert and active, these steps help calm the stomach:

• Give a short fasting break (6-8 hours) – This allows the stomach to settle. (Do NOT fast puppies under 3 months.)
• Keep your dog hydrated – Small amounts of water every 30-45 minutes. Check this hydration guide for simple, daily tips: How to Keep Your Pet Hydrated and Healthy
• Start a bland diet for 24 hours – Examples: Plain boiled rice + boiled boneless chicken, Plain pumpkin puree
• Feed small, frequent meals – Helps dogs who vomit due to empty stomach or bile reflux.
• Slow down fast eaters – Vomiting after eating is very common. Use slow-feeder bowls, smaller meals, hand feeding for puppies.
• Avoid home-cooked leftovers – Spices, oil, and rich food worsen vomiting. This article explains why better: Why You Should Avoid Feeding Home-Cooked Meals to Your Pet
