Laryngitis in dogs is an inflammation of the laryngeal mucosa and submucosal tissue. Clinically, it is characterized by severe cough, throat swelling, warming and pain. According to the cause and clinical course, it can be divided into primary and secondary, acute and chronic. Clinically, acute catalatoid laryngitis is mostly present, and it is often associated with pharyngitis.
1. The cause of laryngitis in dogs is similar to that in dogs.
1. Primary laryngitis is mainly caused by cold, chemical, warm and mechanical stimulation.
2. Secondary laryngitis is often caused by the spread of inflammation in the adjacent organs. Some viral or bacterial infectious diseases (such as canine distemper, influenza, mycoplasma disease, canine adenovirus disease, etc.) often cause laryngitis.
2. Key points for diagnosis of dog laryngitis
Primary acute laryngitis in dogs is easily diagnosed based on cough, increased laryngeal sensitivity, and auscultational stenosis or rales.
1. Cough is the main symptom of this disease. In the early stage, due to the lack of exudates, it is mostly dry and painful. As the exudates increase, the cough sounds are long and wet, and the pain is also reduced. When coughing is worsened when it is cold, it often presents spastic coughing, and vomiting abnormally after coughing.
2. The throat is swollen, the head and neck are stretched, and it is inhaled and dyspnea. In severe cases, it may even cause suffocation.
3. Palpation of the throat, due to swelling of the throat mucosa and increasing sensitivity, the sick dog suffers pain, dodges, shakes his head and stretches his neck.
4. When the throat is auscultation, dry slugs can be heard when there is little exudate and is viscous. When the ooze is thin, you can hear the sound of big water bubbles. When the larynx is severely swollen and highly narrow, the sound of larynx can be heard.
5. Sick dogs sometimes leak serous, mucus or mucus purulent nasal fluid.
6. For mild laryngitis, the systemic symptoms generally have no obvious changes.
7. Severe laryngitis, body temperature rises, pulse increases and difficulty breathing.
8. Chronic laryngitis, long-term fever, blunt cough, and a dull cough sound. The palpation of the throat is slightly sensitive. On nasal and laryngoscopy, the mucosa can be seen to be thick and swollen, and it is granular or nodules.
3. Prevention and treatment measures for dog laryngitis
The treatment principles of dog laryngitis are to strengthen care, eliminate inflammation, and eliminate phlegm and relieve cough.
1. Strengthen care: First remove the primary cause, place the sick dog in a warm and well-ventilated kennel, give soft and easy-to-digestible food, and drink more water to reduce irritation to the throat mucosa.
2. Eliminate inflammation: In order to promote the dissipation of inflammation, accelerate the absorption of exudates, and relieve pain, 10% hypertonic saline and magnesium sulfate solution can be used to warmly apply the throat twice a day: apply 10% camphor alcohol, osmetic ointment and other irritants locally. When the nasal fluid is viscous, use compound benzoin tincture, 1-2% sodium bicarbonate solution, 2% alum solution, and 1-20lo tannic acid solution to vaporize people. If the inflammation is severe, antibiotics and sulfonamide preparations can be used. Penicillin can also be dripped into the throat cavity.
3. Expectant phlegm and cough relief: When coughing frequently, you can use 0.05 grams of morphine hydrochloride, 20 ml of almond water and fennel water, and take one spoonful of oral food each time. Or codeine phosphate solution, 0.50/0 atropine sulfate solution, subcutaneous injection. Because atropine is antagonized with acetylcholine, it has the effect of inhibiting parasympathetic nerves and has an antispasmodic effect on bronchial smooth muscles.
4. In chronic laryngitis, astringents can be dripped into the throat cavity, such as 0.1~0.3% silver nitrate, compound iodine solution and 1% alum solution.
5. If there is a risk of suffocation, the dog's tracheotomy should be performed immediately.
