It's very important to contact your veterinarian immediately. There could be several reasons for this bleeding, and only a vet can properly diagnose the issue and provide appropriate treatment.
Here are some potential reasons for bleeding after birth that a vet will need to investigate:
* Uterine infection: This is a serious condition that can be life-threatening.
* Retained placenta: If parts of the placenta are not expelled, they can cause infection and bleeding.
* Uterine prolapse: This is a condition where the uterus falls out of the vagina.
* Injury: Your dog may have injured herself during labor or shortly after.
Please don't delay in contacting your veterinarian. Your dog's health is a priority.
