Hi ya I'm new to here I'v a 3year old bullie that we matted she had a c section with one very large pup that didn't make it she is now in heat 6/7months on would u mate this season or wait till next? X

After a c-section I'd give at least one clear season to allow the uterus to heal fully.

I've always been advised to leave mating on the next season after a c-section so that her body has time to recover. I would also be prepared that any further litters have to be born this way. My vet will only do an elective C-section once bitch is showing signs of going into labour so that any pups born will be of a viable age.
