Why does my dog ​​have arches?


It is not uncommon to be quiet sitting on the couch and suddenly our dog has arcades. We worry because we think he can't breathe, he wants to vomit and it could be something more serious. In this article we will talk about how to differentiate them, why dogs have them, and what to do to help your animal.

LThe arches are caused by a contracting movement of the abdomen. When this happens, the stomach goes to work to throw out the content that the animal is rejecting through vomiting.

Why do dogs have arches?

Arcades are the attempt to vomit, but this does not always happen. There may be vomiting without them. Also arcades without vomiting. The reasons why your pet can have them are:

  1. You may have already vomited and your stomach is already empty. However, some minimal remains make him have this discomfort.
  2. Maybe he is suffering a stomach dilation.

When the arcades are accompanied by vomiting they can be more serious. Sometimes they can be a sign of some internal damage that we must deal with.

How to know if they are retching or coughing

The arcades and cough are very similar, and to help your dog you have to know how to differentiate them. Sometimes the foam expelled by the mouth of the dog is the result of the effort made by the cough, and not vomiting as often thought.

One of the easiest ways to differentiate from each other is through the sounds. The cough emits a hoarse and dry sound. Meanwhile, the arches emit a sound that comes out of the throat and is more salivating.

As well it is important to know how to differentiate arcades from regurgitation. Although the two try to expel something from the stomach, in regurgitation it is done without arches and abrupt abdominal movements.

What to do if your dog has arcades

Once we know the causes and how to differentiate them from other discomforts, we have to get down to work and help our pet. As we have said, those that are accompanied by vomiting are the most dangerous, so we will focus on them.

These are the steps to follow:

  • Try to find out why it happens. Perhaps it only happens when you have fed him something that is not his food. If you see what happens often, perhaps your food has something that feels bad. If it happens when you come from the street, maybe it is because you have eaten some of the ground. In short, watch your pet.
  • Prevents vomiting. If it happens often, under medical prescription, you could give the dog a preventive medicine so that the time between them is lengthened.
  • Refill your liquids. When you vomit a lot, we tend to get dehydrated and your dog is no less. Therefore, it is vital that you give plenty of water and mineral salts to help you replenish all the lost fluid.
  • If you vomit more than once on the same day, go to the vet as soon as possible.

If you think that the cause of the arches is to have swallowed an object, with many more reason you should go to a specialist. Sometimes it is necessary to take actions that you could not do at home.

Be especially attentive, because if what happens to your dog is a dilation-torsion of the stomach, this could cause death. Don't assume that the arcades are unimportant. Everything that happens in our body, and in this case that of your pet, that goes out of the ordinary, is because something is not going well, and you are responsible for helping him discover what.

The arcades in the dogs

It is common for a dog to have arches like vomiting precedents, which can tell us, if the episode is repeated or we find another symptomatology, which is suffering from digestive disorder We should consult with our veterinarian.

Many times a dog that has vomited several times arches without vomiting when it no longer has any content to eliminate in its stomach. But, sometimes, these indicate another type of problem. In the following sections we will explain the most probable causes of why our dog has arcades.

The presence of foreign bodies

One cause that can explain why a dog has arcades is that it I have swallowed a foreign body and this is lodged in the mouth, throat or esophagus. We talk about objects such as bone fragments, splinters, thorns, threads, needles, hooks, spikes, balls and other toys, ropes, etc.

If these bodies present sharp or sharp edges They can complicate the frame by producing perforations. If our dog begins to show hypersalivation, nausea, retching, rubs his mouth with his legs or against objects, keeps it open, regurgitates or seems nervous, we can think about the presence of some foreign body. If this is found in the mouth, it is sometimes stuck in the tongue and it is possible to locate it when we lift it. If we see it very clearly we can try to extract it.

In any other case it will have to be our vet who does it and anesthesia is likely to be needed. We should never pull a thread if it can carry a threaded needle. If the foreign body remains for hours inside our dog, our veterinarian will prescribe the use of antibiotics in the dog to prevent infections. Objects that reach the esophagus can be detected on an x-ray and removed by endoscope or abdominal surgery. Finally, we must know that if the body is installed in the larynx, the dog will present a cough, choking and respiratory problems.

Pharyngitis and chronic bronchitis

Having any of these conditions could also explain why our dog has arcades. Pharyngitis in dogs is inflammation of the pharynx, as the name implies, and can have different causes. Also, with retching, fever, cough, pain when swallowing and loss of appetite. If we look at the throat we will see it reddened and we can even appreciate pus. We must transfer our dog to the veterinarian to identify the cause of the inflammation and administer antibiotic. It may also be necessary to use pain medications.

Bronchitis in dogs, especially when we refer to bronchitis chronicleOn the other hand, it is a disease characterized by the presence of cough that does not remit in the time. It affects more middle-aged dogs and consists of an inflammation of the bronchi and bronchioles. The bronchial tubes are the ducts in which the trachea is divided when entering the lungs and, in turn, is divided into bronchioles. In this case, the cough that causes this inflammation manifests itself in accesses, usually triggered after exercise or excitement, which end in arcades and even expectoration, which can confuse caregivers who will think that their dog has arcades and vomits white foam or saliva, which is actually expectoration.

Thus, it is common for the caregiver to refer that the dog has retching and coughing as the main symptoms of chronic bronchitis. Is required veterinary treatment to avoid major and irreversible damage and this will consist of a combination of drugs and a series of measures aimed at preventing the access of coughs.


We dedicate, by its frequency, separate section to another disease that can explain why our dog has arcades: tracheobronchitis, better known as kennel cough, well, as it is very contagious, it spreads rapidly in collectivities of dogs, such as the aforementioned kennels, the protectors or the dog residences.

It is transmitted through cough and sneeze It produces but, also, can be spread by accessories or clothing. With kennel cough we can see that our dog has arcades and boogers, in addition to the characteristic cough. In fact, this is going to be the main symptom and, as was the case with chronic bronchitis, its strong accesses are the ones that will end in arcades. By this same mechanism expectoration may appear.

On some occasions, indicating the milder cases, fever, loss of appetite and lethargy may occur. In the most severe cases there will be mucopurulent nasal and ocular secretion, sneezing, disturbed breathing and may even reach pneumonia occur.

Most dogs, on the other hand, maintain the usual mood and appetite, have no fever and the only symptom of the disease is cough. Requires veterinary treatment although, as always, prevention is the best. If our dog is in contact with many others, such as in a busy park, or we will leave it in a dog residence, it is recommended that we properly follow the canine vaccination schedule. And in case the animal is sick, it must be kept isolated.

Torsion / stomach dilation

This is perhaps the most urgent cause, because of the Death risk which means that it can explain why a dog has arcades. Early detection can save your life. Torsion / stomach dilation encompasses two processes, which are as follows:

  • Gastric dilation: in this process the stomach is distended due to gas and liquid.
  • Gastric torsion: in this phase, the distended stomach rotates on its longitudinal axis, which prevents its emptying. The stomach contents begin to ferment, which increases the distention. Blood circulation in the area is also affected and necrosis of the stomach wall and perforation can occur, which will cause a picture of shock and death.

Although this condition can occur in any dog, those of large races, due to their anatomical conformation, have a greater propensity. Rapid intake of food or plenty of water, as well as vigorous exercise before or after the meal can cause it.

The symptomatology includes nervousness, restlessness, hypersalivation, retching and nausea, in addition to abdominal distention. The dog may have pain if we touch his belly and adopt abnormal postures. We must procure urgent veterinary assistance. An x-ray can give us the information to differentiate if we are facing a dilation or torsion has also occurred. In the latter case, surgery will be necessary.

Motion sickness, or motion sickness, is another reason that explains why a dog can have arcades. This disorder is relatively common and we can see it when we travel with our dog in the car, for example. We will observe restlessness, nervousness, hypersalivation, nausea, retching and even vomiting.

We should consult with our veterinarian as it can be corrected and also administered medication To avoid dizziness. Meanwhile, if we have to take our dog by car we can remove water and food a few hours before embarking on the trip. Motion sickness is quite common in puppies and usually disappears with age.

Other causes of dog arches

Finally, we can observe that our dog has arcades if he eats grass or any grass. The causes for which the dog ingests grass are not clear, what is known is that it acts as an irritant in the stomach, explaining, thus, why the dog has arcades and vomits. If we see that this behavior occurs frequently we should consult it with our veterinarian.

On the other hand, eating herbs or soil can make our dog infested with eggs nematodes, which are the most frequent worms that can be found in dogs. They are like "spaghetti" and can sometimes be found in the vomit or feces of the infested dog. In smaller puppies, larvae of these parasites end up in the lungs, and may lead to coughing, nausea and retching. It will be our veterinarian who recommends the most appropriate deworming schedule.

How do I tell if my dog ​​has arches or cough?

In the case of dogs, the arcades are very often confused with the cough when glarge phlegm that looks like a vomit with foam, or when vomiting is caused in attacks of strong cough.

To distinguish the arcades of cough we can look at the sound the dog makes. In the case of the arcades it sounds like "glup" (a guttural sound), while in the cough there is a hoarse sound reminiscent of "chagh".

The arcades also suppose the difference between vomiting and regurgitation. In both the food is expelled from the stomach, but in the regurgitation there is no arch, simply the food is expelled without these violent movements of the abdomen.

In chronic digestive problems, the first step is to distinguish if there is vomiting or regurgitation to be able to reach a diagnosis.

Why does my dog ​​have arches?

If your dog has arcades (don't cough) but do not eject anything, there may be two causes:

  1. You have already vomited the digestive content and your stomach is completely empty (When they are fasting they can expel yellow-green bile).
  2. In dogs of large or giant breed and hounds or bloodhounds it can be a stomach dilation-torsion.

Whenever there is vomiting, you should:

  • Try to diagnose the cause
  • Prevent vomiting with appropriate medication (with veterinary recommendation)
  • Treat the primary cause
  • Replace fluids and minerals that have been lost, with water or serums.
  • If the dog has more than one isolated vomit, it should be go to the vet in the next 24 hours.

If a poisoning is suspected or that the dog has eaten an object (stuffed animals, beds, ropes, threads, stones.) It is better to go to the clinic as soon as possible. Objects can be removed from the stomach by endoscopy, but in the intestine the risk increases and surgery is usually necessary.

As for stomach dilation-torsion, it is a deadly condition for the dog. It is urgent to go to the vet to operate it as soon as possible.

This problem can be diagnosed by an x-ray, although you can have a strong suspicion because the dog swells, especially on his left side and hitting it (with a pair of fingers) sounds hollow.

Stomach dilation-torsion is a problem of unknown cause that is associated with a weakness in the ligaments that hold the stomach in place. It usually occurs after eating, especially with a lot of food and very often bones and when the dog is agitated or nervous.

In the case of dilation, it is a problem in the emptying of the stomach. In the case of torsion we talk about a stomach twistthat leaves the food locked up without being able to move forward or backward, as the entrance and exit twist.

Torsion is more dangerous than dilation and usually drag the spleen and cut off the circulation. It is frequent that in surgery it is necessary to remove it because it has begun to become necrotic (the tissue dies).

In surgery, apart from assessing whether the spleen needs to be removed, the stomach is repositioned and fastened to the abdominal wall in its normal position. This is called gastropexia.

In giant breed dogs that are very predisposed you can program a preventive gastropexia. This is especially recommended for female dogs during castration, since the same surgery is used and only a larger incision must be made.

In short, if your dog has arcades, it is important distinguish if they are accompanied by vomit or not, and explain to the veterinarian everything we observe. If your dog vomits on more than one occasion, or if you suspect that se may have eaten something that should not, you should go to the clinic immediately. In some cases, taking it on time is key to recovery.

My dog ​​pretends to throw up

The first thing you have to worry about, if your dog wants to vomit but can't, is that he is suffering from gastric torsion. This disease requires your immediate intervention, as it can cause the death of your partner in a few days. We can be talking about a gastric torsion when he has crammed himself with eating, then he has done severe exercise and, when he stops, neither eats nor drinks and it seems that he only wants to vomit without success.

What has happened to him is that his stomach has dilated and then twisted on himself. This is caused by a massive intake of oxygen. for eating quickly followed by an explosive activity. The problem is that he will not be able to swallow or vomit and that will end up killing him if you do nothing to remedy it.

Gastric torsion is manifested by these symptoms and a hard touch stomach. Anyway, whenever you see it strange after this chain of events, take it quickly to the vet. To prevent this from happening you have to get used to eating slowly and respect the breaks after each meal.

My dog ​​wants to vomit but nothing comes out

In addition to because of gastric torsion, it is possible that your dog is not really trying to vomit, but trying to move the muscles in his throat to spit something that is stuck in it. You have to have a quick reaction to this and know how to perform the Heimlich maneuver on your dog.

If it is a small breed puppy, take it in the air by the hind legs and shake it gently, that will help. If you can't do it, surround your waist with your arms and push forward. Last resort, give dry blows on the back to help you spit. Use these methods if your dog is calm, if not, do not waste time and visit your veterinarian to have it removed.

To prevent this from happening you have to be very careful with what is brought to the mouth. To learn, be firm when you want to eat something from the street, tell it not dry and sharp and reward it with something rich instead or with a caress. So, little by little, he will understand that it does not make you happy that he does and will cease in his endeavor.

My dog ​​has arcades but doesn't vomit

There are dogs that inherit coprophagic tendencies because of seeing how their moms eat the poops in their environment to clean their cribs, so you have to be patient and correct this behavior little by little. We know that saying it is easier than doing it, so we invite you to get in touch with our ethologists to teach you to correct this attitude.

In case it is not gastric torsion and you do not have something stuck, it may be that you have an irritation in your throat. Your dog will think that clearing his throat will relieve his pain, but it will only get worse. You may also have a wound in your stomach for having eaten something that should not cause you to have arches.

To stay calmer, Get in touch with our online veterinarians. We will be happy to give you advice so that your dog stops having that behavior, valuing, for what you tell us, what may be happening.

When you take your puppy to the vet, he will first rule out a possible gastric torsion. After that you will verify that you have nothing in your windpipe or any irritation. He will examine it and assess whether these arches may be due to another type of disease, both stomach and with another focus. Ask us all your questions without obligation, but fearing that it is torsion, we recommend that you visit your veterinarian urgently to make the possible intervention.
