It is not necessary for dogs to operate to remove foreign objects. If the foreign object is relatively small, the dog can expel it on its own. If the foreign object is relatively large and the dog cannot expel it on its own, it needs to be removed through surgery. You need to keep an eye on your dog and don't let it eat randomly. If you find that your dog has swallowed foreign objects, you should stop it in time to avoid unnecessary trouble. You should also supplement the dog with trace elements to prevent it from developing pica.

The problem of dogs eating foreign objects can be avoided by the following methods:

1. Wear a mask when going out for a walk, hold the leash, and keep an eye on the pet at all times. Stop the action in time. Since pets usually communicate by smelling each other's anus and excrement to get familiar with each other, it is also common for pets to smell everywhere and take up space. The scavengers must learn to distinguish between them.

2. Supplement the dog with more nutrition at ordinary times. Do not feed dog food alone. If the owner is free, he can make some homemade food for the dog, such as beef soup, chicken rice, carrot rice, Bone soup, fish soup, etc. In terms of ingredients, they can also be more comprehensive. Vegetables, fruits, fish, nuts, aquatic products, etc. are all good choices.

3. It is also a good choice to feed the dog a quick nutritional supplement for dogs regularly. The owner also needs to keep the home clean and prevent the dog from coming into contact with soil, feces and other things.
