Here are some things you can do while waiting for your vet's advice:
* Don't try to induce vomiting. This could potentially worsen the situation.
* Keep your dog calm and comfortable.
* Observe your dog closely. Note any changes in behavior, appetite, or bowel movements.
Remember, a veterinarian is the best resource for this situation. They can advise on whether your dog needs further treatment, like surgery, or if the bone will pass naturally.
