Motion sickness
Though they may love going for rides in the car with you, motion sickness is a common cause of vomiting in dogs. If you’re noticing that your dog is only vomiting during (or shortly after) car rides, motion sickness is likely the culprit.
Medications/supplements
Some dogs simply don’t take well to certain medications, and vomiting can be an indication of this. If your dog is currently taking medication for an existing health condition and has been vomiting regularly, the medication could be the cause.
Also, while they may provide additional benefit to a dog’s diet, certain ingredients in canine nutritional supplements may not agree with all dogs. If your dog’s vomiting has started since beginning a new supplement regimen, there may be an element in the formula that irritates their digestive system, or you have started on a too high dose.
Irritable Bowel Disease (IBD)
Irritable bowel disease is not strictly reserved for humans; our dogs can experience it, too. When a dog’s gut health isn’t balanced, their digestive system can become chronically irritated. This can lead to full-blown IBD, which often includes vomiting [2].
Acid reflux
Acid reflux is a condition whereby intestinal or gastric fluid comes up from the stomach and flows into the esophagus, and is another common cause of retching and vomiting. If your dog is vomiting a yellow substance, acid reflux may be the reason. Read our expert article on Acid Reflux in Dogs for more detailed information.
Hunger pukes
Hunger pukes’ in dogs refer to episodes of vomiting when a dog’s stomach is empty. Also termed Bilious Vomiting Syndrome, people may mistake this condition for acid reflux, as both can result in similar symptoms like retching and vomiting. However, hunger pukes are identifiable by the yellow or green, frothy appearance of the vomit, which occurs due to stomach inflammation and bile presence. They frequently occur when a dog’s stomach is empty, commonly late at night or early morning. Adjusting ingredients, meal times, and portion sizes can alleviate this issue. Providing a late-night snack can also prevent hunger pukes in dogs.
Parasites
As dogs explore the world with their noses and often eat things they shouldn’t, it’s generally a good idea to rule out parasites when it comes to dog vomiting. Microscopic parasites such as giardia, and other types of worms, can cause vomiting in dogs; as well as robbing them of nutrients and hydration.
More serious health conditions
Aside from the more common causes, vomiting in dogs can occasionally be a symptom of more serious health concerns. Some of these might be:
- Pancreatitis
- Kidney issues
- Intestinal blockages
- Tumours
- Poisoning
These may sound scary, but they’re less common than you think. Also, there are often other warning signs aside from your dog vomiting that may indicate a more serious condition. Before you start to worry, read our “When to contact the vet” section below.
