Grundlagen und mögliche Ursachen
A dog’s airways consist of the nose, throat, larynxThe larynx is an organ in the upper respiratory tract that contains the vocal cords and is important for speaking, breathing, and swallowing. The larynx also serves as a protective mechanism that prevents food and liquid from entering the trachea., tracheaThe trachea, or windpipe, is a tubular organ that carries air from the upper respiratory tract to the bronchi in the lungs. It consists of ring-shaped pieces of cartilage that ensure it remains open., and bronchi, which lead to the lungs. Any impairment or blockage of these structures can lead to altered breathing sounds. The most common causes include mechanical obstructions, Inflammatory conditions or an infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease., as well as structural abnormalities.
A common reason for loud breathing sounds is respiratory tractThe respiratory tract includes the organs and structures involved in the breathing process, including the nose, pharynx, larynx, trachea, bronchi, and lungs. infections. ViralViral refers to viruses and their effects on the organism. Viral infections in dogs and cats can range from harmless colds to severe, life-threatening diseases. and bacterial infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease. can cause Inflammatory conditions and mucus buildup that obstruct airflow. For example, bronchitis or Pneumonia can cause crackling breathing sounds.
Allergic reactions can also triggerA trigger is a stimulus that elicits a specific reaction or state. In veterinary medicine, this can refer to emotional responses, such as fear or aggression, or medical conditions, such as seizures in dogs and cats. breathing sounds. Allergens such as pollen, dust, or mold can irritate the airways and lead to Swelling, narrowing the normal air passages and making breathing difficult.
Structural abnormalities, as commonly seen in short-nosed dog breeds (brachycephalic breeds), can also lead to loud breathing sounds. These breeds often have shortened airways and are prone to breathing problems due to narrowings or overlaps in the nasalNasal refers to the nose and nasal cavities. In veterinary medicine, this can involve examinations, treatments, or diseases affecting the nose of dogs and cats. and throat area.
Foreign bodies that are accidentally inhaled or swallowed can also block the airways and create altered breathing sounds. In such cases, prompt veterinary intervention is often necessary to remove the blockage.
Another possible cause is a heart problem that can lead to pulmonaryPulmonary refers to the lungs or the respiratory system. Pulmonary diseases in dogs and cats include conditions such as Pneumonia, asthma, and pulmonary hypertension. edemaAn edema is a buildup of fluid in the body's tissues, leading to Swelling. Edema can be localized or generalized and is often a sign of an underlying condition.. Fluid then accumulates in the lungs and causes a crackling sound when breathing.
Typische Begleitsymptome
- Cough: A common companion of breathing sounds, indicating that the dog is trying to clear the throat or lungs of mucus or foreign bodies.
- Shortness of breath: If the dog is breathing faster or more heavily than usual, this may indicate a serious airway obstructionobstruction refers to the blockage or narrowing of a hollow organ or canal, which hinders the normal flow of liquids or gases. In dogs and cats, an obstruction can occur in the digestive tract, airways, or urinary tract and often requires immediate medical treatment. or lack of oxygen supply.
- Sneezing or nasalNasal refers to the nose and nasal cavities. In veterinary medicine, this can involve examinations, treatments, or diseases affecting the nose of dogs and cats. discharge: a sign of a possible infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease. or allergy affecting the airways.
- Bluish mucous membranes: A serious sign of oxygen deficiencyDeficiency means a lack or absence of a necessary substance required for normal bodily functions or health, such as vitamins, minerals, or hormones. that requires immediate attention.
- Loss of appetite and lethargy: General malaise or exhaustion that may accompany respiratoryRespiratory refers to breathing or the process of breathing. Respiratory diseases affect the respiratory tract and can impair the ability to breathe effectively. problems.
- Vomiting or Gagging: These symptoms may occur in dogs trying to remove a foreign object from the tracheaThe trachea, or windpipe, is a tubular organ that carries air from the upper respiratory tract to the bronchi in the lungs. It consists of ring-shaped pieces of cartilage that ensure it remains open..
Wann zum Tierarzt?
A veterinary visit is essential if the breathing sounds occur suddenly or are accompanied by other alarming symptoms, such as bluish mucous membranes, labored breathing, or extreme lethargy. These symptoms may indicate serious airway impairment or a lack of oxygen.
If the dog shows signs of choking or is clearly in respiratoryRespiratory refers to breathing or the process of breathing. Respiratory diseases affect the respiratory tract and can impair the ability to breathe effectively. distress, seek an emergency veterinarian immediately. Airway blockages caused by foreign bodies can quickly become life-threatening.
Likewise, persistentPersistent means lasting or continuing for an extended period. In veterinary medicine, it can refer to chronic diseases or symptoms that do not subside. or worsening symptoms, even if they initially appear mild, should be examined by a veterinarian to rule out more serious causes and begin appropriate treatment.
Symptomerkennung für den Tierhalter und tierärztliches diagnostisches Vorgehen
For pet owners, it is important to pay close attention to changes in the dog’s breathing pattern. Signs include unusual sounds when inhaling or exhaling, increased Cough or Sneezing, and obvious RespiratoryRespiratory refers to breathing or the process of breathing. Respiratory diseases affect the respiratory tract and can impair the ability to breathe effectively. distress.
The veterinarian will first perform a thorough clinical examination to assess the dog’s overall health and identify possible external signs of respiratoryRespiratory refers to breathing or the process of breathing. Respiratory diseases affect the respiratory tract and can impair the ability to breathe effectively. disease. This also includes listening to the lungs with a stethoscopeA stethoscope is a medical instrument used for auscultation, or listening to body sounds, such as heartbeats and lung sounds. It is a fundamental tool in medical diagnostics. to detect abnormal sounds such as crackles or wheezing.
Depending on the suspected cause, further diagnostic tests may be required. Chest X-rays can provide information about structural abnormalities or fluid accumulation in the lungs. An endoscopyEndoscopy is a diagnostic procedure that uses an endoscope (a thin, flexible tube with a light source and a camera at the end) to examine and visualize the inside of the body, often for diagnostic or therapeutic purposes. can be used to examine the airways directly and locate any foreign bodies.
Blood tests may be performed to look for signs of infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease. or Inflammatory conditions. In some cases, a cardiac ultrasoundUltrasound refers to sound waves that are above the hearing threshold of the human ear. In medicine, ultrasound is used for diagnostic imaging procedures to visualize internal organs, tissues, and blood flow. may also be indicated to rule out cardiovascular causes.
Was kann der Tierhalter tun und professionelle Therapieoptionen
Until the veterinary examination, pet owners can take a few steps to support their dog’s well-being. A calm environment without stressStress refers to the state of an organism reacting to external stimuli or demands. In veterinary medicine, stress can have physical or psychological effects on animals, impacting their health and well-being. and excitement can help make breathing easier. Avoid physical exertion, especially in heat, to prevent additional strain on the airways.
Keep the dog in a cool, well-ventilated room to make breathing easier. Humidifiers can be helpful in dry air, as they moisten the airways and can make breathing easier.
If an allergic reaction is suspected, minimize possible triggers such as pollen or dust. Clean the dog’s sleeping areas regularly and avoid contact with known allergens.
It’s important not to medicate the dog on your own without consulting the veterinarian. Some over-the-counter medications can be dangerous for dogs or worsen other health problems.
If you suspect a foreign body in the airways, do not try to remove it yourself, as this can cause further injury. In such a case, acting quickly and transporting the dog to the veterinarian is crucial.
