What Size Crate and Bed Do You Need for TPLO Recovery?

Why are generic crate charts not enough?

Crate brands measure products differently, and dogs of the same weight can have very different body proportions. A 42-inch label does not guarantee a particular interior floor measurement. For a post-operative dog, the exact fit matters more than the size printed on the carton.

How should you measure?

1. Measure the dog from nose to the base of the tail while standing, then observe the dog lying in its natural, comfortable position.
2. Record the usable lying length and width. Do not force a painful limb into an extended position.
3. Measure the crate’s inside floor length and width, accounting for door hardware, rounded corners and interior dividers.
4. Compare the pad’s actual sleeping surface—not its outside seam dimensions—with the crate floor.
5. Check that the finished pad does not bunch, curl or obstruct the doorway.

How should the crate fit?

Use the enclosure size specified by the treating team. Do not use a generic “large enough to pace” rule or intentionally squeeze the dog into a tiny crate. Ask the clinic to confirm the correct crate or pen dimensions for your dog, especially if the dog needs assistance to stand, turn or reposition.

What if the dog is long-bodied?

For a Dachshund or another long-bodied dog, measure the dog’s own resting footprint rather than relying on a weight-based chart. The bed should support the torso along its natural length. If a standard pad leaves the shoulders or hips unsupported, compare a longer pad only if it still fits the approved enclosure. Do not improvise with folded blankets that create ridges or uneven layers.

How much clearance should the pad leave?

There is no universal inch allowance that works for every crate model. The pad should lie flat and the crate door should close normally. A product that must be compressed, folded or forced into place is the wrong size. If the pad covers a latch or creates a raised edge, choose another option.

What should you ask the clinic?

• Which exact confinement area is allowed: crate, kennel, pen or small room?
• What interior dimensions are suitable for this dog?
• Does the dog need space for a sling, support or prescribed equipment?
• Are there restrictions on bed thickness or entry height?
