A six-month-old collie appears to have a developmental deformity where the bones in its elbows don't fit together, but after CT scans, Noel sees that the situation is even more complex. A Burmese mountain dog has a painful bulging disc, which Noel hopes to replace with a bespoke titanium spacer screw, while cat Elmo has a complex fracture to its left back leg after being hit by a car.

Noel treats 15-stone English mastiff Bear, who has a ruptured ligament in his knee - but as the dog goes into theatre, a major team effort is needed to get this massive patient through surgery. Siamese cat Bluebell is rushed in after being hit by a car and golden retriever Henry is suffering from a chronically damaged spinal disc.
