Methods to determine if your dog has swallowed a foreign object:

1. Restless. If a foreign object is stuck in the throat, the dog will be very agitated and always scratch its neck with its front paws, showing symptoms such as lack of energy and loss of appetite.

2. Frequent vomiting. When clinical symptoms occur, they usually include vomiting and abdominal pain. The closer the foreign body is to the stomach, the higher the frequency of vomiting and the more severe the clinical symptoms.

3. Have an X-ray examination. If it is suspected that the dog has swallowed a foreign body, it is recommended that the owner take the dog to the hospital for an X-ray examination to confirm whether there is a foreign body in the dog's gastrointestinal tract.

How to deal with a dog that has swallowed foreign objects:

1. Induce vomiting. If the dog swallows it soon or it is stuck in the throat, you can try to induce vomiting by picking it with your hands or using soapy water to induce the dog to vomit out the foreign object.

2. Lubricant assists excretion. You can help dogs excrete foreign matter from their bodies by feeding them lubricants, vegetable oils, sesame oils, etc.

3. Surgical removal. If the swallowed foreign body is relatively large, it is recommended to send it to a pet hospital for examination immediately. If necessary, the foreign body can be removed through surgery.
