What is bilious vomiting syndrome?
Bilious vomiting syndrome is a condition in which your dog vomits because his stomach is inflamed from excessive bile secretion. Bile is a fluid that helps aid digestion.
This condition is also referred to as duodenal-gastric reflux and reflux gastritis syndrome.
What will bilious vomiting syndrome look like in my dog?
Your dog will generally seem normal except for an increased tendency to vomit, especially in the morning. The vomit will generally be composed of whole food and a yellow liquid which is actually bile and mucus from the stomach.
How does my dog get bilious vomiting syndrome?
Bilious vomiting syndrome tends to be seen most often if your dog is fed only once daily, usually in the morning. What is happening is that your dog is not being fed often enough to absorb the bile. Instead, the bile sits in your dog’s stomach and interferes with the stomach’s protective lining which allows acid to irritate the stomach. The irritation causes inflammation which, in turn, leads to the vomiting.
