My Dog is Vomiting – Should I Call the Vet?

When you see your dog vomiting, it can be unsettling and leave you wondering what’s going on. Dogs vomit for many different reasons, ranging from something minor like eating too fast to conditions that require urgent veterinary attention. As a pet owner, knowing when to call your veterinarian makes all the difference in protecting your pet’s health. In this blog, we’ll explore the common causes of dog vomiting, signs that suggest it’s more serious, and what steps you can take when your dog suddenly gets sick.

 

 

Why Does Dog Vomiting Happen?

Dog vomiting is a symptom, not a condition in itself. Understanding why it occurs helps you recognize when it’s a one-time event and when it might signal something more concerning. Vomiting happens when the body forcefully expels stomach contents. This reflex may be triggered by irritation, infection, or other underlying health issues.

Common Triggers for Dog Vomiting

• Dietary indiscretion – Dogs often eat garbage, spoiled food, or non-food items. This is one of the most frequent causes of vomiting.
• Eating too quickly – When dogs gulp food or water rapidly, they sometimes vomit immediately afterward.
• Sudden diet changes – Switching foods without a transition period may upset the digestive tract.
• Motion sickness – Many dogs vomit during car rides, especially younger pets.
• Food sensitivities – Certain ingredients may not sit well with your dog’s stomach.

Occasional dog vomiting from these causes may resolve on its own, but frequent episodes suggest something more serious.

Vomiting vs. Regurgitation: How to Tell the Difference

Pet owners often confuse vomiting with regurgitation, but they are not the same. Being able to tell the difference gives your veterinarian more accurate information when you describe your dog’s symptoms.

Signs of Vomiting

Vomiting is an active process. You’ll notice retching, abdominal contractions, and drooling before your dog expels the contents of their stomach. The vomit often contains bile, partially digested food, or foamy liquid.

Signs of Regurgitation

Regurgitation is passive. It usually occurs suddenly without effort, often soon after eating. The material looks like undigested food, and your dog may act normal immediately afterward.

Both vomiting and regurgitation can signal a health concern, but vomiting is generally more urgent since it often indicates irritation, infection, or obstruction.

When Is Dog Vomiting a Concern?

A single episode of dog vomiting may not be alarming, especially if your pet seems otherwise normal. However, vomiting becomes worrisome if it’s frequent, severe, or accompanied by other symptoms.

Warning Signs to Watch For

• Vomiting multiple times in one day or over consecutive days
• Blood in the vomit or material resembling coffee grounds
• Signs of abdominal pain, such as whining or a hunched posture
• Refusal to eat or drink for more than 24 hours
• Diarrhea combined with vomiting
• Sudden weight loss or ongoing loss of appetite
• Weakness, collapse, or difficulty standing

If your dog shows any of these symptoms, it’s time to call Animal Family Veterinary Care Center at (563) 391-9522.

Potential Health Concerns Linked to Dog Vomiting

Not all causes of dog vomiting are minor. Some may be life-threatening if left untreated.

Gastrointestinal Obstructions

Dogs sometimes swallow toys, bones, or household objects. These items can block the digestive tract, leading to severe vomiting, restlessness, and abdominal pain. Blockages require immediate veterinary attention.

Infections and Parasites

Bacterial infections, viral illnesses, or parasites like roundworms can irritate the stomach and intestines. Vomiting often occurs alongside diarrhea, fever, or lethargy.

Toxin Ingestion

Certain foods, plants, and household chemicals are toxic to dogs. Chocolate, xylitol, grapes, and cleaning products are common culprits. Vomiting may be the first sign your dog ingested something dangerous.

Organ and Metabolic Issues

Kidney disease, liver disease, or pancreatitis can cause recurrent vomiting. These conditions typically worsen without treatment, making early detection important.

Age-Related Concerns

Young dogs are more likely to vomit from parasites, infections, or eating non-food items. Older pets may vomit due to organ dysfunction, tumors, or chronic illnesses. Age can help your veterinarian narrow down potential causes when evaluating your dog.

What to Expect at Animal Family Veterinary Care Center

When you bring your dog to our care center, our veterinary team will gather a detailed history and perform a physical exam. Diagnostic testing may also be recommended to determine the cause of vomiting.

Diagnostics for Dog Vomiting

• Bloodwork – Provides information about organ function, infection, and hydration status.
• Fecal exam – Detects intestinal parasites.
• X-rays or ultrasound – Identifies blockages, masses, or gastrointestinal abnormalities.
• Urinalysis – Helps assess kidney and bladder health.
• Specialized tests – May be ordered depending on your dog’s symptoms.

These tools help your veterinarian create a treatment plan tailored to your dog’s condition.

Can Dog Vomiting Lead to Dehydration?

One of the biggest risks of repeated vomiting is dehydration. When your dog loses fluids through vomit and refuses to drink, their body becomes unbalanced.

Signs of Dehydration

• Dry gums
• Sunken eyes
• Lethargy
• Loss of skin elasticity

If dehydration develops, your dog may need fluid therapy at the clinic. Quick intervention restores hydration and helps prevent complications.

Can Dog Vomiting Be Prevented?

Not all vomiting can be avoided, but there are practical steps pet owners can take to lower the risk.

Helpful Prevention Tips

• Introduce new foods slowly over 7–10 days.
• Prevent scavenging by keeping garbage secure and supervising outdoor walks.
• Avoid feeding fatty table scraps or human food.
• Provide slow-feeder bowls to discourage rapid eating.
• Store medications, plants, and toxic items safely out of reach.

Prevention won’t eliminate every cause of vomiting, but it significantly reduces risk.

Seasonal and Environmental Factors That Affect Vomiting

Certain times of year or environmental conditions may increase the likelihood of dog vomiting.

Warm Weather Concerns

In hot weather, dogs may experience heat-related stomach upset or drink excessive amounts of water, leading to vomiting. Outdoor barbecues and picnics also increase exposure to fatty foods and bones.

Cold Weather Concerns

During winter, dogs may vomit after eating snow treated with salt or chemicals. Antifreeze exposure is another serious risk during colder months. Staying aware of seasonal hazards helps protect your dog year-round.

Why Acting Quickly Matters

Dog vomiting may appear minor, but it can quickly lead to dehydration and reveal serious underlying conditions. Acting promptly allows for earlier diagnosis and better outcomes.
