If your dog is throwing up undigested food once in a blue moon, then there is no need to panic; he will usually be back to his normal routine within a few hours. If the vomiting did not stop, then you need to understand that there is a problem with your dog.

Why dogs usually throw up undigested food?

There are many reasons why dogs throw up undigested food. We will discuss all the reasons one by one.

Vomiting is defined as the forced, involuntary, or voluntary emptying of the stomach through the mouth. In vomiting, the contraction occurs in the stomach muscle, and sometimes, along with undigested food, yellow bile with a sour smell appears.

Vomiting occurs due to many reasons. It usually happens when your dog eats too much or eats too fast because some dogs are naturally greedy. It may be that your dog has picked up something from the trash, or any harmful grass can cause vomiting.

If white foam comes along with vomit and it is followed by a runny nose, eye discharge, and a dry cough, then it is a sign of kennel cough.

Onions, chocolate, and grapes can cause toxicity and vomiting in dogs. Some dogs who like to dig in the trash can suffer from food poisoning and vomiting.

Sometimes you see that your dog regurgitates the food and then returns to eating or the puppy next to the mother ate the regurgitated food. This mainly happens when puppies are in the transition phase from mother’s milk to solid food and need help during this phase. The mother regurgitates at this point to provide partially digested food for her young.
