My dog doesn't want to eat and just vomits

If your dog is sad, does not want to eat and vomits, the most important thing you should learn to distinguish in these cases is whether it is an occasional vomit of no great importance or something that is of some or great seriousness.

The same thing happens with him not wanting to eat, it is not serious, but if he does not start wanting to eat for several days (48 – 72 hours)… we have to take action on the matter.

If the dog is sad, well, that is relative and not easy to interpret, but if you see him off for 1-2 days, you should start worrying.

What we cannot let more than 24 - 48 hours pass is a dog that meets all or most of the signs described in the previous paragraph, that is, it is vomiting, does not want to eat, dull, sad... not there. We must allow more than 2-3 days to pass before attending your veterinarian, to begin initial treatment.

Why do dogs vomit?

The act of vomiting, be it dogs, humans or any mammal in general, is often due to a reflex act to preserve life. The body detects a harmful agent in the stomach and in an attempt to defend itself it tries to expel it through vomiting.

When we get dizzy we often feel the need to vomit, this is another reflex action in which the body.

When you begin to decompensate due to said dizziness, you try to expel gastric contents from within, in case that were the cause, although it is not always the case.

When faced with a lack of oxygen, a common reaction is vomiting. If we lack oxygen we start to get dizzy and we already saw in the previous paragraph how dizziness exerts an emetic effect (vomiting) on the body.

Everything explained above applies the same in a dog as in a human and in mammals in general, that explains why dogs vomit.

Vomiting in dogs, when to worry

Two of the most common questions about nutrition are: “my dog doesn't want to eat” and the other is “my dog doesn't want to eat and is vomiting.”

The first, in general, is not serious.

The second is more disturbing and can range from mild to an illness that compromises life in the short or medium term.

Here, we can find a kidney condition, but also pancreatitis, liver problems, etc. Let's focus on that dog that doesn't want to eat and vomits. 

Vomiting or regurgitation (reflux) in the dog?

It is very important to understand the difference between vomiting and regurgitation (it is actually gastroesophageal reflux, but for practical purposes we are going to call it regurgitation).

It is very common to confuse them; For practical purposes you must understand the following: in vomiting there is expulsion of complete and large quantity of food, while in regurgitation there is NO expulsion of food, only white and/or yellow viscous liquid (WHITE and/or YELLOW FOAM), that is the main difference.

Regurgitation. You should know that it is a very common cause of medical consultation, in general it is not serious, it is not easy to control it, doctors usually send drugs such as proton pump inhibitors to the stomach for these cases.

Do they work? Sometimes yes sometimes no. It's bad? As I already told you, in general it is not serious.

In my medical experience I can assure you that the vast majority subside or disappear if the dog is fed with natural food well prepared by you, and above all give a little of this food in the early hours of the morning, which is when the symptoms usually occur most. regurgitation.

Threw up. It is the central topic of this article, and as you have already been reading, there are vomiting that ranges from temporary, anecdotal and unimportant, to serious and life-threatening. 


As we have already mentioned, a dog not wanting to eat is not that serious, but if he is down, there is vomiting. Alarm! Things are not right, there is something wrong, it may be temporary, but what if it isn't?

If 24 – 48 hours pass and there is no improvement, I recommend that you do not waste time and go to your veterinarian, it is the best.

Remember something very important, learn to distinguish between vomiting and regurgitation (reflux), this is essential to avoid false diagnoses and excessive alarms.

Remember, love your dog, feeding him with food or croquettes, in addition to being abusive, is terrible nutrition, give him natural food made by you.
