The reasons why a dog is retching accompanied by a clicking sound but in good spirits:

1. If there are hair, dust, flying insects and other foreign objects in the dog's throat, the dog will feel uncomfortable and want to dry it out. Vomiting will expel it. At this time, the owner needs to clean the foreign matter in the throat. If it is a foreign body that cannot be discharged, surgery will be needed to remove it. If it is phlegm, some phlegm-reducing drugs will be given.

2. Dogs are infected with internal parasites such as roundworms and tapeworms. A large number of parasites swim in the body, which can cause retching. Owners must deworm their dogs regularly.

3. It may be that the mild cold caused by weather changes has not completely resolved, and the bronchus is still slightly inflamed. You can feed the dog some pet-specific cold medicine to get better as soon as possible.

4. If you cough frequently, there may be problems with the trachea and lungs. You need to go to the hospital for relevant examinations for further diagnosis and targeted treatment.

5. When a dog is very excited or has not been active for a long time, and then suddenly undergoes strenuous exercise, retching may also occur, especially for puppies with poor cardiopulmonary capacity. At this time, the owner needs to Give your dog some watery fruits to relieve the pain.

6. It may be that the dog accidentally eats relatively large food, such as bones, etc. The sound is usually caused by throat discomfort and needs to be taken out in time.

7. Feeding too many bones, dry food, etc. can easily lead to indigestion and retching in dogs. At this time, the dog should eat more easily digestible food.
