There’s a lot you can learn about your dog’s health based on the condition of the vomit he throws up. Throwing up isn’t necessarily a sign of serious health condition. Some dogs, for example, may vomit and recover fine after eating something they shouldn’t have.

However, as a dog owner, it’s best to err on the side of caution and to call the vet for advice, especially if your dog is throwing up orange vomit. Here are a few reasons for dogs that may be experiencing this.

1. Your Dog Has an Upset Stomach

Dogs sometimes may throw up a substance that’s unusual in color. This is more prevalent when they throw up on an empty stomach. The orange substance that comes out might be the bile and stomach acids, which can appear in several different colors aside from orange including yellow and green.

2. Your Dog Ate Something Orange

The dog may have simply eaten something that’s orange in color and didn’t react well against. For example, dogs can eat oranges (the fruit) in small amounts but their stomach may not have reacted well against the acidic content of the fruit. As a natural reflex, the dog may end up throwing up the content, which leads to the appearance of the partially-digested food content.

3. Sign of a Serious Health Condition

In the worst case scenario, the act of throwing up orange vomit might be a sign of a serious health problem. This is more likely if you notice your dog exhibiting other concerning symptoms, such as excessive shaking, within the same time period. These cases should be treated as an emergency and we would recommend calling the vet right away, especially if your dog is not acting like his usual self.

This can also happen if your dog ingested something toxic or unsafe. For example, your dog may have wandered into the garden and inhaled pest control products like sevin dust. This can lead to vomiting as one of the symptoms. It’s important to call the vet straight away if you suspect this is the case.
