Why does my dog ​​vomit and have diarrhea

Vomiting like diarrhea in dogs are processes that are common in a way and in certain cases they can be a reason for their owners to feel worried, especially if these do not decrease, the appearance of blood occurs either in vomit or in the feces or if said clinical picture becomes more serious when accompanied by other symptoms such as anorexia, listlessness or fever.

It is for this reason that we bring the necessary information to explain the reason why my puppy vomits and has diarrhea at the same time.

Vomiting in dogs are symptoms of a disease

In order to explain why a dog has vomiting and diarrhea, the most common is that we focus on the digestive system, because the most common causes of this type of disorder usually originate in a gastrointestinal problem, which in this way has the ability to affect the stomach, the large intestine or also the small intestine, which causes certain variations in the appearance that vomiting usually has or diarrhea.

It is necessary that we can find differences between vomiting and spitting up, since in the first case it is when an effort occurs and we observe movements in the abdomen area, while on the other hand when a regurgitation occurs the food or also the liquid comes out easily.

In this way, it is important to understand that diarrhea is those stools that happen very frequently and are quite liquid, which in turn can very easily differentiate any trace of blood. When fresh blood is seen in the stool, it is called hematochezia.Meanwhile, the one that has been digested, which usually has a darker tone, is called the mane.

It is important that we be very attentive to each of these characteristics, since when the time comes we must give all the necessary information to the veterinarian so that he can give a diagnosis, and then administer the correct treatment.

The fact that our pet vomits occasionally or also when he has diarrhea without the need to present other symptoms and having the possibility of keeping his mood intact, is not something we have to worry about., but when these episodes occur repeatedly in a fairly short period of time or usually occur recurrently in a few weeks or months, it is a reason to take our dog in front of a veterinarian, as well as when it shows any other symptoms in addition of which we have explained.

The main causes of vomiting and diarrhea

With the necessary information, the necessary exams and each of the tests that are considered pertinent, the veterinarian is the one who will be able to determine among the great number of different causes that can explain the appearance of vomiting and diarrhea. However, we can mention the most common:


Well what they are caused by bacteria, viruses or protozoa, among the symptoms of these are vomiting as well as diarrhea and need a treatment administered by a veterinarian.

For indigestion

When dogs usually have a tendency to overeat, which also includes the food or products found in the remains left by humans in their consumption or in the garbage and despite the fact that a dog's stomach is prepared to be able to process certain edible components, it is quite common for they end up causing diarrhea as well as vomiting that usually diminish spontaneously.

Food allergies or intolerances

In this type of cases we observe the presence of vomiting as well as diarrhea in a chronic way, apart from the fact that they are accompanied by some other symptoms, such as itching.

Es specialist follow-up necessary, that all the necessary tests are done for allergies in the dogs and that a diet that is hypoallergenic is implemented.

Pharmaceutical products

Certain medications can cause digestion disorders that can cause diarrhea as well as vomiting. It is important to indicate all the necessary information to our veterinarian when our dog is being medicated, as well as we have to give the name of the drug as well as the dose.

The underlying diseases

In certain cases, there are disorders such as some renal disease, which shows as part of its consequences in the body the presence of vomiting and diarrhea.

Generally are detected through a blood test and each of these symptoms diminishes taking into account the way in which the disease is controlled.

By obstructions

When dogs are gluttonous, it is quite common for them to eat an object, such as bones or a toy that reaches cause an obstruction in some part of the digestive system. In certain cases where said object can cause damage and it is not recommended that it come out by itself, the only way to remove it is through surgery.


The fact of consuming some foods can cause poisoning where the main symptoms are diarrhea and also vomiting. These types of problems are usually from veterinary emergencies, which also endanger the life of our pet.


When the cases of parasites are too serious or when this occurs in those animals that are more vulnerable, it is possible to observe vomiting and especially diarrhea. The specialist when examining a sample of the stool, has the ability to determine what kind of parasite is causing the problem and therefore, the indicated medication will be administered.

When we are at this point, it is very important to point out the opportunity to be able to set a schedule for deworming properly.

Due to stress

In many cases of canine stress very serious or when it lasts for a long period of time, our dog can suffer from vomiting as well as diarrheaTherefore, it will be necessary to request the help of a specialist veterinarian.

Bloody vomiting and diarrhea

If your dog spends a lot of time in bed, he may be sick

As we have already explained, blood in the stool may appear fresh or being digested and depending on what the case is, it receives a different name. This is one of the factors that can help us to know the reason for this, which makes it much easier to explain vomiting and bloody diarrhea.

When the blood is fresh it means that we are talking about a condition in the internal part of the digestive system, but if it has been digested, most likely it comes from the stomach, the small intestine or it may even be from the respiratory tract that later ends up inside the digestive system by swallowing.

On the other hand, the presence of vomiting is a sign that tells us that it is also a gastrointestinal disorder.

What to do if my dog ​​vomits and has diarrhea?

Perhaps this is the great question that you have asked yourself and why you have come here looking for help to that sad and uncomfortable situation in which you find yourself. And we will try to help you as much as possible, although the first thing we recommend is that call the vet and consult him (It is the best way to get a professional answer).

That said, when a dog has vomiting and diarrhea, it goes through several phases. It can be mild, medium, or severe. In most cases it is not serious, and the causes can be simple, meaning that the not feeding for 3-4 hours, or even 24 hours, nothing would happen as long as you drink water often to stay hydrated.

Once those hours have passed, you can give him some bland food to see how you tolerate it. If he does not vomit or have diarrhea, it may have passed, although we recommend that you continue on a soft diet for a few days observing the dog to see if it recurs again.

Otherwise, you will have to go to the vet because, if once a "clean" is done on the stomach, the animal still has problems, these may be due to other causes.

It goes without saying that, if during the wait your pet becomes more listless, is duller, complains ... or has any behavior that is unusual for him or that sets you off alarms, call the vet.

Treatment for dogs that vomit and have diarrhea

There are many treatments for treating a vomiting dog with diarrhea. Some are vet-specific, such as medications, but there are home remedies that, while waiting, can be tried and that would not negatively affect the condition of your pet.

One of those remedies that you can try is the put in the water where you drink, a pinch of bicarbonate. You have to try to drink every 1-2 hours and each time you must prepare that remedy. Why the bicarbonate? Because it serves to calm the stomach and control its acidity. In addition, as long as you do not go overboard with the amount, it is not something that will harm the dog, but on the contrary.

Another option, also with water, is prepare chamomile and ginger infusions. Wait for it to cool down and give it a drink instead of the water. There are dogs that tolerate it very well, and others that, because of the simple smell, do not want to drink it. Here there are two possibilities, the one that you remove it and water them; or force it a little and, with a syringe, give the infusion yourself by putting it in your mouth. If your pet sees that it relieves him, he will most likely end up drinking it alone in the long run.

Peppermint tea is also another possibility to "settle" the animal's stomach and help relieve any pain it may feel. Likewise, chamomile with anise can be another way to prepare an infusion.

Finally, and although it would not really affect the ongoing picture of a dog that vomits and has diarrhea too much, it can help you prevent other situations as well. We talk about the use of probiotics in your diet, either in capsules, in liquid or as a meal.

In the case of the vet, the normal thing when you go with a box like that is to put some antidiarrheal or antiemetic medications. They are very effective and the truth is that you find them as bismuth subsalicylate or the one known as famotidine. Now, it is necessary that this is prescribed by a veterinarian since, although they are over-the-counter digestive medications, which help the stomach, it is not convenient to self-medicate your pet.

When a puppy vomits and has diarrhea

A puppy, by the fact of being such, has greater problems if he goes through a picture of vomiting and diarrhea since it can affect him especially and cause his health to be resented. Therefore, it is advisable to closely monitor the animal in all aspects: food, hygiene, environment ... to avoid it.

When a puppy has vomiting and diarrhea it is that become dehydrated much faster than an adult specimen. And this is due to their immune system, which leaves them open to many other diseases or other parasites that can affect them and aggravate the situation they are going through.

That is why it is so important that the vaccination and check-up schedule is maintained, in addition to that, if your puppy begins to vomit and have diarrhea, the best you can do, without waiting even 24 hours, is to take him to the vet for examination. In this way, if it is something serious, it can be caught in time and at least alleviate the animal.

How to prevent this problem

There are many diseases that dogs can have

Before finishing, and as we know that once you go through this situation the least you will want is to repeat it, we are going to leave you a series of tips to help your pet not to vomit and have diarrhea again.

Among what you can do is the following:

  • Check your pet's diet. You should see if it is the most suitable for him and if it does not cause repeated pictures over time, of vomiting and diarrhea. If so, change your diet.

  • Don't let your dog eat outside the home. In the garbage, when you go out for a walk, and even from other people. You have to get him used to the fact that only you feed him because, that way, you will know that he is not going to eat anything that may be in bad condition or that compromises his health.

  • Do not take it through very dirty areas. Always avoid places that are dirty or poorly cared for because they can be a nest for infections, ticks, parasites, etc. that would endanger your pet.

  • Hygiene to the maximum. Related to the above, you also have to take care that your dog is well cared for so that it does not contract diseases that affect it.

  • Avoid eating what you should not. For example toys that you can destroy and that, consciously or unconsciously, end up swallowing them, because it can be a cause of these vomiting and diarrhea (in addition to having to go to the vet and undergo an operation).

  • Give him the food little by little. This for the most greedy dogs, since many of the problems they have and why they vomit or have diarrhea is because they eat too quickly. But if instead of giving all the food at once, you divide it, you will make the problem go away.
