Oh wow 300$ for a Csection. It is 800.00 Here.
My vet care for my female for pregnancy was 1,000. That did not include care for the babies. ( that was Emma)
This time Gracie had 1 baby, The baby got sick and cost over 500.00
Now add Gracie's care. Shots EEKK BUT at 8 weeks the baby is the picture of health

That makes it worth it.
There is no such thing as a quick profit in breeding. Not if you provide the care they all need.
