1. Measure Length
Measure your dog from the base of the neck to the base of their tail while they are standing.
2. Compare Your Dog's Length to the Inner Sleeping Area
The inner sleeping area is the flat surface between the bolsters, where your dog actually rests.
Your dog's body length should fit comfortably within it.
Note: The XL is 53 inches (4'5") long. Designed for giant breeds, please measure your dog and room first
