Dogs are known to have vomiting periods sometimes, therefore, you shouldn’t be worried every time your dog is sick. However, sometimes there is cause for concern, if you see your dog throwing up undigested food after they have eaten.
In this article, we will be uncovering why your dog is throwing up undigested food hours after eating. With a couple of treatments that you can try to use on your dog to help relieve their sickness.
The Difference Between Regurgitation And Vomiting
It isn’t pleasant to see anybody throwing up, but it can be extremely unnerving to see your dog throwing up. However, if you notice your dog is throwing up undigested food just after they have eaten.
Then the chances are that your dog may be regurgitating their food they have just eaten, rather than vomiting.
As a result, it is important that you learn and get a good understanding of the difference between regurgitation and vomiting, so that you can take the right course of action.
Regurgitation is the process of your dog passively bringing up undigested food. Thus, your dog will typically lower their head and passively cough the food they had just eaten out.
The food will easily come out, almost in the same state as it was eaten. Generally, there will be no sign of a warning from your dog that they are about to regurgitate their food.
Alongside this, the food will still be undigested as it never reaches the stomach in the first place. However, it may have a much more tubular or cylindrical shape, due to being passed through the esophagus.
Also, the food will be surrounded in a slimy mucus that from the esophagus as well. This mucus is what helps your dog to bring the food up so easily.
Henceforth, you can tell that your dog has regurgitated their food, as it looks almost the same as it was when they ate it. In some cases, your dog will re-eat their regurgitated food, as it never reached their stomach. It may also still be appetizing to your dog in this new state.
Compared to when your dog is vomiting. They will generally act a bit strange and begin to drool more than normal. You will notice the muscles in your dog will begin to contact, and you will see their whole body tense up.
Another common sign that your dog is vomiting is that you will see or hear your dog retching. What they bring can be undigested and partially digested food. There will also be a clear liquid if the food has been brought up from the stomach.
Or you will see a green liquid, and this is if the food has come from the small intestines. Your dog will be uncomfortable, and their stomach is known to make loud whining and gurgling sounds.
It can be difficult to tell the difference between if your dog is vomiting or regurgitating. In some cases, a dog can vomit quite quickly after they have eaten. Yet there are cases when a dog is known to regurgitate hours or days after they have eaten.
If you are unsure which of the two is happening to your dog. Then the best thing to do is take a sample to your vet for them to examine. An experienced vet will be able to give you the answer just by looking at the sample straight away.
However, if they are unsure, they can run a simple pH test to get a clear answer. It is known that the pH for vomit containing food is very acidic. Compared to the pH for regurgitated food, which is a lot higher up on the pH scale.
Why Is Your Dog Throwing Up Undigested Food After Eating?
We have now done through the différance between your dog throwing up and regurgitating their food. As we now know the difference, we can look into why your dog may vomit up their food after eating.

It can either happen straight after your dog has eaten, or they could start throwing up several hours after.
As a result, we need to discuss why your dog could vomit or regurgitate straight after eating.

This will happen when your dog’s body doesn’t properly process the food they have eaten as they aren’t used to it.
Or your dog could have a certain food intolerance, like humans, thus their body will try to remove it from their body quickly.
Giving your dog bad food or something that is inedible, then their digestive tract will refuse to break that food down. Then it won’t get absorbed into their body, which means it will need to be removed from the body, normally through throwing it back up.
Sometimes, if your dog eats something that is very solid, like a bone or a stone. This can then block the digestive tract and will immediately begin to throw up to clear the digestive tract. As this item will stop any digestion getting in place.
