Loss of voice in dogs refers to the inability or significant difficulty of a dog to produce sounds that are normally expressed in the form of barking, whining, or growling. This symptom can occur acutely or chronically and often manifests as hoarseness or complete silence when the dog tries to make noises.

Can Occur with the Following Diseases:

Basics and possible causes

A dog’s vocal expressiveness depends primarily on the function of the larynx, vocal cords, and associated muscles and nerves. The larynx is a complex structure consisting of cartilages, muscles, and ligaments that work together to produce vibrations that are perceived as sounds. If any part of this structure is impaired, loss of voice can occur.

One of the most common causes of loss of voice is inflammation in the larynx area, also known as laryngitis. This can be caused by infections, such as viruses or bacteria. Allergies or irritations from foreign bodies or environmental factors such as smoke or dust can also promote laryngitis.

Another cause can be damage to the nerves that control the muscles of the larynx. These neurological problems can be caused by injuries, tumors, or degenerative diseases. A specific condition that causes paralysis in the larynx is laryngeal paralysis, which occurs mainly in older, large dog breeds.

Mechanical problems, such as injuries from collars or leashes, can also lead to loss of voice. In some cases, tumors or polyps in the laryngeal area can also impair the normal functioning of the vocal cords.

Typical accompanying symptoms

  • Hoarseness: The dog produces sounds that sound rougher or weaker than usual. This may indicate inflammation or mechanical impairment of the vocal cords.

  • Cough: A dry, hacking cough can be an accompanying symptom, especially if there is an infection or irritation of the respiratory tract.

  • Respiratory distress: Difficulty breathing, especially during physical exertion, may indicate a narrowing of the airways due to swelling or tumors.

  • Difficulty swallowing: Problems swallowing may indicate general swelling or a foreign body in the throat area.

  • Lack of energy: A general malaise or lethargy can occur, especially if there is a systemic infection or a serious illness.

When to visit the vet?

A visit to the veterinarian is absolutely necessary if the loss of voice is accompanied by shortness of breath, as this may be a sign of a serious impairment of the respiratory tract. A veterinarian should also be consulted if the loss of voice occurs suddenly and for no apparent reason or lasts longer than a few days.

If the dog also shows other symptoms such as severe cough, loss of appetite, general weakness or weight loss, a rapid veterinary examination is necessary to rule out serious underlying diseases.

Veterinary advice should also be sought immediately for dogs that are prone to laryngeal paralysis or have an increased risk of certain diseases due to their breed or age.

Symptom recognition for animal owners and veterinary diagnostic procedures

The recognition of loss of voice and its causes often begins with the pet owner noticing that their dog no longer barks or makes other sounds as usual. A close observation of the accompanying symptoms can give the veterinarian important clues as to the cause.

The veterinarian will first take a thorough anamnesis to understand the course and circumstances of the loss of voice. A physical examination, especially of the neck and head area, will be performed to identify swelling, pain, or obvious blockages.

In many cases, further diagnostic tests are necessary. These may include blood tests to rule out infections or systemic diseases. A laryngoscopy, in which the larynx is viewed directly, can also be performed to identify structural changes or foreign bodies.

Imaging procedures such as X-rays or an ultrasound examination may be necessary to detect tumors or other internal problems that could affect the larynx or nerves.

What can pet owners do and professional therapy options

The pet owner can take some measures to provide relief to the dog and avoid possible damage. This includes keeping the dog away from possible irritants such as smoke or strong chemical odors.

It is important to keep the dog calm and avoid excessive exertion so as not to additionally burden the respiratory tract. For dogs with laryngeal paralysis or respiratory distress, increasing the humidity in the room can help to ease breathing.

Avoid pulling on the collar, as this could further irritate the larynx. Instead, a harness can be used to take the pressure off the neck.

Make sure the dog drinks enough water to keep the mucous membranes moist. If the loss of voice is related to an infection, the veterinarian may prescribe antibiotics or other medications that should be administered according to the instructions.

It is important to continue to monitor the dog and consult the veterinarian again if the symptoms worsen or new symptoms occur to ensure appropriate treatment.

Outlook on current research

Research on loss of voice in dogs focuses on understanding the various causes and mechanisms that can lead to this symptom. Studies show that loss of voice in dogs is often caused by respiratory diseases such as laryngitis or tracheitis. Researchers are currently investigating how inflammation in these areas affects the vocal cords and can lead to a loss of vocal ability. A better understanding of these mechanisms could lead to new treatment approaches that aim to reduce inflammation and restore normal vocal cord function.

Another area of research is the genetic predisposition to loss of voice in certain dog breeds. Some breeds are more susceptible to respiratory diseases that can cause loss of voice. Researchers are looking for genetic markers that could explain this susceptibility. Identifying such markers could make it possible to develop targeted breeding programs to reduce the risk of loss of voice in susceptible breeds.

In addition, the role of environmental factors such as allergens or pollutants in the air is being investigated. These can also cause inflammation in the respiratory tract and lead to loss of voice. Current studies are investigating how reducing these environmental factors could reduce the risk of loss of voice in dogs. This research could help to create better living conditions for dogs and minimize the occurrence of loss of voice.

Technological advances also enable scientists to use advanced imaging techniques such as magnetic resonance imaging (MRI) and endoscopy to examine the anatomy and function of the vocal cords and surrounding structures in detail. These techniques offer deeper insights into the physical changes associated with loss of voice and help to make more precise diagnoses. In the long term, this could support the development of more targeted therapy approaches.

Another exciting field of research is the investigation of therapeutic interventions that aim to restore vocal cord function. These include both pharmacological approaches, such as the use of anti-inflammatory drugs, and physical therapies that can promote the recovery of the vocal cords. Initial clinical studies show promising results, but further research is needed to confirm the effectiveness and safety of these treatments.

Overall, current research shows that loss of voice in dogs is a complex symptom with a variety of causes. However, advances in science offer hope for improvements in prevention and treatment that could ultimately improve the quality of life of affected dogs.
