Squeeky bark

My 5 year old Bully bitch has developed a squeek that occurs when she is barking, it suddenly breaks into a squeek, similar to a young mans'' voice breaking. Could this be an infection in the throat or something like a bone lodged in her throat. She catches and eats birds

Changes in barking noises are usually acquired conditions/diseases that occurs in dogs. I will very briefly discuss 4 common causes below (in no particular order):

Laryngeal paralysis results from damage to the nerves that control the movement of the larynx which ultimately affects the sound produced. Bull Terriers are one of those breeds affected by this condition. A classic sign of laryngeal paralysis is a characteristic croupy or “roaring” noise heard as the dog inhales. Initially it appears during or after exercise. Later it occurs at rest. Another sign is progressive weakening of the bark, which ends in a croaky whisper. In time the dog develops noisy breathing, laboured breathing, reduced exercise tolerance, and fainting spells. Laryngeal swelling may develop and further compromise the airway, causing respiratory collapse and even death. The diagnosis is made by examining the vocal cords with a laryngoscope. Paralyzed vocal cords come together in the middle instead of remaining well apart. This produces a tight air passage through the larynx.
Treatment: A number of surgical procedures have been used to enlarge the airway. The technique used most often involves removing both the vocal cords and their supporting cartilage. This relieves the obstruction, but the dog is unable to bark. Surgery may also predispose the dog to aspiration pneumonia, so usually medical therapy is tried first.

Laryngeal Trauma Choke chain injuries, tight slip collars, or any rope around the neck can fracture the hyoid bone and/or cause compression damage to the nerves of the pharynx and larynx. Other causes of trauma to the larynx include bite wounds and sharp foreign objects such as bones and pins that penetrate the larynx. Dogs with laryngeal injuries often breathe normally at rest but show respiratory distress during exertion.
Treatment: Treatment of laryngeal trauma involves confining and resting the dog and administering anti-inflammatory medications. If the larynx is severely traumatized, a tracheostomy (an operation in which an opening is made through the skin into the trachea to establish a new airway) may be required. Choke chain injuries can be prevented by using a buckle collar, head halter, or chest harness.

Laryngeal Collapse This is a late stage in airway obstruction. Pressure changes in the upper airway caused by stenotic nares, an elongated soft palate, laryngeal paralysis, or everted laryngeal saccules stretch the ligaments that support the laryngeal cartilages. These cartilages gradually collapse inward and block the airway. At this stage any change in the dog’s need for air can cause acute respiratory insufficiency and cardiac arrest.
Treatment: The first step is to surgically correct predisposing factors. If symptoms persist, the dog may benefit from a permanent tracheostomy.

Laryngitis is inflammation and swelling of the vocal cords and surrounding laryngeal mucosa. The signs are hoarseness and the inability to bark. The most common cause of laryngitis is voice strain caused by excessive barking or coughing. In the absence of these, suspect vocal cord paralysis. Laryngitis can accompany tonsillitis, throat infections, kennel cough, or tumours in the throat.
Treatment: Laryngitis due to excessive barking usually responds to removing the stimulus for the barking. When voice strain is due to prolonged coughing, take your dog to the veterinarian to investigate and eliminate the cause of the coughing. An animal suffering from an infectious cause will often have other symptoms as well e.g. loss of appetite, fever, gagging, pain and/or coughing when the neck is touched or a collar is applied, etc.

Visiting your veterinarian will be the best way to distinguish between these conditions and decide upon the most appropriate form of treatment, while also minimizing the discomfort to the pet.
