Is It Dog Vomiting Or Regurgitation
One important thing to keep in mind is that dog vomiting and regurgitation are not the same thing. Think of dog vomiting as more of an active process and regurgitation as more of a passive practice.
Why do you need to know the difference? Because the causes of and treatments for the two conditions are very different, and vomiting tends to be more concerning than regurgitation.
Should I Be Worried About My Dog
Vomiting blood mixed with mucus makes the likelihood of a serious issue more likely. However, there are also often simple explanations such as a viral or bacterial infection or eating something foreign. These dogs will not vomit more than a few times and should not appear overtly ill. However, vomiting may often be the first sign letting you know that something is seriously amiss.
If your dog is vomiting and you see mucus and blood in the vomit, the issue may also be simply a broken blood vessel in the esophagus, but could also be a sign of a very serious issue. Lets review the most common causes.

Vomiting Vs Regurgitation In Dogs

To treat dog vomiting, you need to know the difference between a dog vomiting and regurgitating.
Regurgitation is when undigested food comes back up into the mouth from the esophagus. This happens when food is too large for deposit into the stomach.
If your dog regurgitates, youll notice undigested food mostly covered in mucus. Regurgitation doesnt involve the stiff-legged heaving that vomiting does. Its quick and unfortunately usually involves your dog eating the food a second time.
Sure, this is gross, but its also completely normal. Regurgitation provides another opportunity to crush food into smaller pieces.
Regurgitated food rarely smells unless your dog is eating kibble. Kibble fed dogs tend to regurgitate and vomit much more than raw fed dogs. This is because many brands of kibble contain rancid ingredients covered up with masking chemicals.
So, the main difference is that the purpose of regurgitation is an adjustment and the purpose of vomiting is to get rid of toxic material.
Vomiting comes from the stomach and the upper intestines. It usually has a unique texture, color and smell.
