A fire started in an upstairs dishwasher at Medivet veterinary clinic in Southend, Essex, England. When the Essex Fire and Rescue Service arrived, they found a vet performing surgery on a dog. Firefighters battled the blaze and evacuated other animals, and also protected the operating room until the surgery could be completed.
A spokesman from the fire service said: "The main problem was the smoke-logged building.
"Crews assessed the situation and decided it would be safe for the operation to continue."
A high pressure fan was used to clear the building of smoke.
