My female leo has severe MBD. She cannot walk and cannot shed properly. Since she cant walk she cannot eat. She's forced to walk with her feet and toes curled inward, and usually walks on her elbows. Her spine is mis-shaped into an "S" shape. She needs to be put down, however I need to know how much this costs. I've heard its cheap but I need the exact price. Has anyone had one put down at the vet before? How much did it cost?
