Normal birth after c-section

Question
Can a queen have a normal birth after a c-section? What concerns me it the incision, if there is the slightest opening in the muscle tissue of her stomach, can that cause a problem, or maybe I'm feeling scare tissue? Her stomach will just stretch as the babies grow, it will not tear the old incision will it?

Answer
Georginia,

How long ago was the C-section?

Normally, once an incision heals and the stitches are out, except for the scar, you would never know there was surgery.  The skin on the abdomen will stretch as the babies get bigger and, no, will not open up, assuming all was done correctly by the vet, and the C-section was many months ago.

Best regards... Norm
