Why does my dog ​​vomit and have diarrhea?

Vomiting and diarrhea are relatively common processes in dogs and Sometimes they may worry their caregivers, especially if they do not remit , bleeding in vomit or stool appears or the clinical picture worsens with other symptoms such as anorexia, apathy or fever.

Vomiting and diarrhea

To explain why a dog vomits and has diarrhea, it is usual to focus on his digestive system , since the most common causes of this disorder have their origin in a gastrointestinal dysfunction that , therefore, it will be able to affect the stomach, small intestine or large intestine, which will produce some variations in the appearance of vomiting or diarrhea.

We must distinguish between vomiting and Regurgitation , because the first one, the one that concerns us, is the one that occurs with effort, so we will see abdominal movements and sounds, while in the regurgitation the food or the liquid comes out alone.You also have to know that we will understand diarrhea the frequent and liquid stools .In addition, we can distinguish the presence of blood.In feces, fresh blood is called hematochezia, while digested, which appears with a dark color, It will be called mane.

We must pay attention to everyone These data to, where appropriate, transmit all the information to our veterinarian to reach the diagnosis and, consequently, to the treatment.That our dog vomits in a timely manner or even has diarrhea without presenting more symptoms and keeping intact intact is not worrying, but if these episodes are repeated in a short period of time or occur on a recurring basis for weeks or months, it is a matter of veterinary consultation, as if our dog showed also other symptoms.

The main causes of vomiting and diarrhea

Observing our dog we will have the information that we have mentioned to communicate it to our veterinarian.With all this, the examination of our dog and the tests that it considers pertinent, our veterinarian will discriminate between the very diverse causes that explain by that our dog vomits and has diarrhea.The most common are the following:

• Infections : both caused by bacteria and by viruses or protozoa, produce vomiting and diarrhea and should be treated by a veterinarian.
• Indigestion : Dogs have a tendency to overeat, including questionable products such as remains of human consumption or garbage and, although their stomach is prepared for some of these "edibles", it is not strange that they end up causing diarrhea and vomiting that usually remit spontaneously.
• Food intolerances or allergies : in these cases we will see vomiting and diarrhea chronically , in addition to others yes More frequent symptoms such as itching.It requires veterinary follow-up, allergy testing for dogs and the implementation of a hypoallergenic diet.
• Medications : Some drugs produce digestive disorders translate into diarrhea and vomiting.We must inform our veterinarian if our dog is medicating, as well as provide the name of the medication and its dose.It will be necessary to suspend or change the treatment.
• Underlying diseases : sometimes, there are disorders, such as kidney disease, which among the consequences they cause in the body include vomiting and diarrhea.They are usually detected in a blood test and this symptom will remit depending on how we can control the disease that is behind.
• Obstructions : because of the gluttonous character of dogs it is not uncommon for them to ingest objects such as bones or toys that produce an obstruction at some point of the digestive system.On occasions when the object can cause damage and it is not feasible to leave alone, it is necessary to resort to surgical intervention.
• Poisoning : the ingestion of some products can cause a picture of poisoning whose symptoms include vomiting and diarrhea.They tend to be veterinary emergencies with danger to the dog's life.
• Parasites : in very serious cases of parasitosis or when it occurs in especially vulnerable animals vomits and, above all, diarrhea can be observed.The veterinarian, examining the feces, will be able to determine what type of parasite we are and administer the appropriate dewormer.At this point it is important to highlight the relevance of establishing an adequate deworming schedule.
• Stress : in cases of very severe stress or when it is prolonged in the time, the dog may have vomiting and diarrhea and will need the help of a professional.

Given the number of possible causes for vomiting and diarrhea in dogs we will look, in the following sections, in three specific situations as an example.

My dog ​​vomits and has bloody diarrhea

We have seen how blood can appear in the feces in fresh (hemactechian) or digested (mane) form.This aspect helps us locate the place of origin of it, what will facilitate explaining why our dog vomits and has diarrhea, in this case, with blood.

Fresh we will see it in conditions of the lower part of the digestive system (thick, rectum, rectum and anus), while, if it appears digested, it will come from the stomach, small intestine and even respiratory tract that ends in the digestive system by swallowing.

The presence, also, of vomiting, guides us to diagnose a gastrointestinal disorder .Also, we must look to see if our dog has other symptoms or, on the contrary, remains calm.It would be our veterinarian who has to determine the exact cause among all the possible ones to be able to start the appropriate treatment.

My dog ​​vomits, has diarrhea and does not eat

Vomits, diarrhea and anorexia, that is, lack of appetite, describe the typical picture of gastrointestinal disorders .It is easy to understand that, with "belly pain" our dog does not want to eat.As we have seen, it can be a specific situation that is not serious caused by, for example, a binge.

These mild cases remit spontaneously in a few hours and only if the dog gets worse or the picture does not stop should we go to our veterinarian to investigate why our dog vomits and has diarrhea.During these episodes we should not offer water or food to our dog since If you are vomiting and eating or drinking, you will vomit everything we give you.

Once a few hours have passed, we can offer you a little (no!) water so that you only have a couple of drinks.If after half an hour he has not vomited, it means that he tolerates it and we can give him a little more.In these mild cases the dog does not usually dehydrate.In a couple of hours without vomiting or diarrhea we can offer you food.If the episode has been very mild this food may be yours, but in a small amount, like a stitch, to see if your body accepts it well.

When there has been vomiting for an hour it is better to restart the feeding with a special diet, more digestive , such as those found in veterinary clinics.We can also give you some rice , cooked ham or chicken, without salt or sauces, or plain yogurt without sugar.Once the episode is resolved, prevention is essential for cases of diarrhea and vomiting that we can avoid, such as those caused by eating too much or inadequate food.

We can follow the following recommendations :

• Avoid our dog's access to potentially toxic substances such as detergents or insecticides but also to food human, because some foods are not suitable for pe Rros consume them, or trash.We must also prevent them from playing with potentially dangerous objects that could be swallowed.Also discover 10 common things in the home that can kill your cat.
• Accustom it to its food and that it is of quality, in the dose recommended by the manufacturer.
• Follow the schedule of vaccinations and deworming recommended by our veterinarian as this will avoid some serious infections caused by viruses and also the negative effect of intestinal parasites.
• Never medicate our dog without a veterinary prescription.Even the most common drugs in human medicine can even be fatal for a dog since they do not metabolize them just like the human organism.
• Offer adequate life habits that avoid stress.
• Go to the vet when vomiting and/or diarrhea contain blood and do not remit or the dog has more symptoms.Also, from approximately 7 years of life it is recommended that our dog spend a at an annual veterinary review in which, at a minimum, a blood test is performed, it is possible to detect diseases in early stages, susceptible to vomiting and diarrhea.

My puppy vomits and has diarrhea

Finally, we address in this section the particular situation of puppies, due to their special vulnerability .The causes that cause gatrointestinal disorders in them will be fundamentally the same as those that explain because an adult dog vomits and has diarrhea.The peculiarity is that puppies, especially the youngest ones, can easily become dehydrated and, in addition, because of the immaturity of their immune system, they are more likely to diseases and parasites cause them more serious damage than they can cause an adult dog.

Therefore it is necessary to be scrupulous with compliance with the schedule of deworming and vaccines , safety measures and, in this case, when vomiting and diarrhea occur, if we must contact our veterinarian, especially when these fluids appear bloody, as they can indicate the presence of canine parvovirosis, enf life-threatening viric disease characterized by vomiting and profuse bloody diarrhea.
