With more than 19,000 clients, Dr. Pol is stretched to the limit. To keep up with calls, he adds Dr. Sandra to the staff. A farm girl at heart with lots of large animal experience, Dr. Sandra treats a downed horse with lesions that make it nearly impossible to stand and nurse her colt. Elsewhere, Dr. Brenda is called to treat a bloated cow in critical condition. Without treatment the cow will die, but with one simple procedure, she miraculously has him off the ground and eating in minutes.
