Correlation between investigator-obtained morphological measurements and measured speed for 57 dogs in a study to develop a low-technology system that minimally trained dog owners can use to obtain these measurements in companion dogs.

Morphological measurement (cm)	On-leash trial with owner		On-leash trial with investigator		Off-leash trial		Stair trial 1*

Forelimb length	0.31	< 0.001	0.08	0.02	0.04	0.08	0.03	0.10
Torso length	0.23	< 0.001	0.01	0.22	0.001	0.34	0.01	0.61
Right thigh circumference	0.28	< 0.001	0.03	0.11	0.04	0.07	0.01	0.25
Left thigh circumference	0.23	< 0.001	0.03	0.12	0.03	0.12	< 0.001	0.32

^*Stair trial 1 was conducted in the clinic on the same set of stairs for each dog; 3 of 57 (5%) dogs did not complete stair trial 1. A separate home stair trial (trial 2) was conducted by owners 2 weeks after the clinic visit (results not included).
