Radiographic measurements obtained for 87 dogs.

Variable	Median (range)	Mean ± SD
Subcutaneous fat thickness (mm)*	19.3 (3.7–55.1)	22.0 ± 12.3
Length of T4 (mm)	18.8 (7.6–27.1)	17.8 ± 4.5
Width of T8 (mm)	19.5 (8.6–31.3)	19.2 ± 5.4
Ratio of subcutaneous fat thickness to T4 length (T4 ratio)	1.2 (0.2–3.5)	1.3 ± 0.8
Ratio of subcutaneous fat thickness to T8 width (T8 ratio)	1.1 (0.2–3.7)	1.2 ± 0.8

^*Measured on the dorsoventral or ventrodorsal radiographic projection at the level of the eighth rib head; for each dog, the mean value for measurements of the left and right sides was used.
