Here's why:
* Bleeding can be serious: Even light, watery blood can indicate a deeper injury.
* Infection risk: Open wounds are vulnerable to infection.
* Underlying conditions: The bleeding could be a symptom of a more serious underlying medical issue.
What you should do:
1. Control the bleeding: Gently apply pressure to the wound with a clean cloth.
2. Transport your dog: Take your dog to the nearest veterinary clinic or emergency animal hospital as soon as possible.
3. Provide information: Tell the vet about the wound, how it happened, and how long it's been bleeding.
Don't wait to see if the bleeding stops on its own. A vet can properly assess the wound, stop the bleeding, and provide necessary treatment.
