Possible causes of mute voice in dogs:

1. Damage to the vocal cords. The most common reason why a dog's voice becomes hoarse is due to loss of its vocal cords. This is usually caused by dogs barking for a long time.

2. Due to the new environment. If the dog has just been brought home or the owner has moved to a new home, the dog will be in a state of anxiety and nervousness because it is unfamiliar with the surroundings, and will develop muscle tension and hoarse voice.

3. Caused by illness. If your dog suffers from oral diseases, such as oral ulcers, throat inflammation, acute tracheitis, respiratory tract infection, etc., your dog will also have a hoarse voice.

4. Being frightened. If the dog is frightened by external sounds or objects, the muscles in the throat will tighten due to tension, resulting in a hoarse voice, which may also be accompanied by trembling symptoms.

Medicine that dogs can take if their voices are hoarse:

1. If it is caused by acute or chronic laryngitis. Pet antibiotics and glucocorticoids can be taken orally, and therapeutic effects can be achieved through aerosolized inhalation of antibiotics and glucocorticoids.

2. You can use honeysuckle and Pangdahai to brew it and let your dog drink it, which can effectively eliminate local throat inflammation and relieve hoarseness.

3. For daily care, you can feed some Naiweijian.
