10 Common Causes of Dog Vomiting

November 23, 2023by Nicole Tengco0

Dog vomiting is a common occurrence, and seasoned dog parents know it all too well. It’s never a pretty sight, and it can be concerning because we often can’t tell why they’re throwing up. It could be due to a number of reasons ranging from simple indigestion to serious health conditions. 

Understanding the common causes of dog vomiting can help you identify when it’s time to seek vet consultations or when it’s just a minor issue that you can easily deal with at home. Here are some of the most common reasons your dog may be throwing up:

1. Your Dog Ate Something It’s Not Supposed To

One of the most common causes of dog vomiting is dietary indiscretion. Dogs, especially puppies, are known for their curious nature, which often leads them to eat things they aren’t supposed to. 

This may include anything from table scraps, garbage or inedible objects like plastic. When your pup eats something bad, it can irritate their stomach and cause them to vomit.

2. Your Dog Ate Too Much or Too Fast

Dogs that eat too much or too quickly may also vomit. This is because their stomach gets stretched beyond its capacity, leading to discomfort and sometimes vomiting. Slow-feeding bowls can help prevent this issue. It may also be best to control the portions well and avoid free feeding.

3. Your Dog Hasn’t Adjusted to Its New Diet Yet

A sudden change in your dog’s diet can disrupt their stomach and cause them to throw up. It’s always best to slowly introduce new food into your dog’s diet over a period of seven to ten days.

4. Your Dog May Be Experiencing Gastrointestinal Issues

Dogs may also vomit due to gastrointestinal (GI) issues, such as gastritis, pancreatitis, or gastrointestinal obstruction due to the ingestion of foreign objects. In these cases, vomiting is often accompanied by other symptoms like loss of appetite, lethargy, and diarrhea, among others.

If you suspect that your dog is throwing up due to GI issues, it may be best to schedule an online vet consultation soon.

5. It May Have Parasites

Parasites in the gastrointestinal tract include roundworms, hookworms, whipworms, or tapeworms, which can wreak havoc in your dog’s GI system. Regular deworming can help prevent this issue.

6. It May Be a Side Effect of Certain Medications

Some medications may cause vomiting in dogs. If your dog has been recently put on a new medication and you notice vomiting, it’s worth discussing with your vet.

7. It Ate Something Toxic

Ingestion of toxic substances can lead to an upset stomach in dogs. These substances may include toxic plants, chemicals, and certain human foods like chocolate or coffee. If you suspect your dog has ingested anything toxic, contact your vet immediately.

8. Your Dog Has Food Allergies

Dogs can be allergic to certain food items, and one of the signs of food allergies can be vomiting. If you suspect a food allergy, it’s important to consult with your vet to identify the allergen and eliminate it from your dog’s diet.

9. Your Dog Has Underlying Health Conditions

Certain health conditions, such as kidney or liver disease, cancer, or certain infectious diseases, can cause vomiting in dogs. If your dog vomits persistently, loses weight, or shows other signs of illness, it’s important to seek veterinary attention immediately.

10. Motion Sickness

You read that right—just like us, dogs can also get motion sickness. Long car rides may not be ideal for some dogs, as they can experience nausea and vomiting. Make sure to monitor if your pup is throwing up right after car rides.

The Takeaway

In conclusion, while vomiting is quite common in dogs, it’s important to monitor your dog’s behavior and symptoms closely. Understanding the common causes of dog vomiting can help you take the necessary steps to ensure the health and well-being of your furry friend. However, when in doubt, always consult a professional. Your pet’s health should always be a priority.
