What to do if a dog swallows a peach pit:

1. No food or water. When it is discovered that a dog has swallowed walnuts, the dog must first stop eating and drinking to prevent foreign bodies from further damaging the digestive tract.

2. Check the oral cavity. Check the inside of your dog's mouth. If you can see a foreign object stuck in the mouth, you can try to remove it with tweezers.

3. Help vomiting. Put the dog's head down and its hind limbs up, keeping the front low and the back high. Pat the dog's back with your hands. At the same time, insert your fingers into the dog's mouth and press the dog's tongue to help the dog vomit.

4. Intestinal lubrication. If the walnut cannot be removed, you can give the dog a small amount of cooking oil to increase intestinal lubrication and facilitate the better discharge of the peach pit.

5. Hospital examination. Please take your dog to the pet hospital for examination immediately and do not handle it yourself.
