Cast vs. Splint for Dogs and Cats — What's the Difference?

A cast for a dog or cat fully encircles the limb and is custom-molded using fiberglass — providing rigid, close-fitting immobilization ideal for fractures and sprains below the elbow or stifle. A splint for a dog or cat is a rigid brace applied alongside the limb, often used when swelling is present, secured with tape or gauze rather than full encirclement.

This kit is designed for a hard fiberglass cast.

How to Apply a Fiberglass Cast for a Dog or Cat Leg

1. Prepare the limb: Sedation or anesthesia is typically used to reduce stress and ensure proper limb alignment. Apply adhesive tape stirrups to cranial/caudal or medial/lateral surfaces.
2. Apply stockinette: Roll stockinette over the limb distal to proximal, leaving extra length at each end to fold back over cast edges.
3. Add cast padding: Apply 1–2 layers of cast padding, overlapping ~50%, with extra padding over bony pressure points.
4. Wrap fiberglass cast tape: Wet the fiberglass roll and wrap distal to proximal, overlapping ~50%, molding over joints in a functional position.
5. Secure and finish: Fold stockinette and stirrups back over cast edges and tape down. Allow to fully set before weight-bearing.
6. Monitor daily: Check toes twice daily for warmth, swelling, and discoloration. Keep cast clean and dry. Return to vet every 7–14 days or sooner if issues arise.
