It's summer in central Michigan, and high temps and humidity are taking a toll on everyone, especially the furry felines. The clinic is full with one upper respiratory infection after another. Meanwhile, Dr. Lisa checks for signs of infection around the heart of a large steer, and Dr. Pol examines a six-week-old colt.

The vets are out on farm calls and they make sure that every animal has a fighting chance. Dr. Pol tangles with a feisty bull and performs pregnancy checks on a herd at House Dairy. Dr. Lisa treats a horse with a large wound on its leg that isn't healing and staves off a deadly infection with antibiotics.
