If your dog is stuck in something and keeps coughing, it is best to help the dog take out the foreign object immediately to prevent the dog from suffocating. First, check whether a foreign object can be seen in the dog's throat. If it can be seen, it can be taken out directly with chopsticks or tweezers; if it cannot be seen, you can use the Heimlich first aid method.
Tip:
If it doesn’t work after several attempts, you need to send the dog to the pet hospital immediately to find a doctor to remove it.
