entitled "Variation in the Body
Size of the Red Fox" written

Most importantly, he measured their chests. Chest measurements are only given for Italian fox, and sample size is not noted for the studies in the other countries. To easily convert European measurements to U.S. or English measurements, go to: www.onlineconversion.com Italian foxes varied from a minimum weight of 7.2 pounds and a minimum chest size of 10.43 inches to a maximum weight of 17.9 pounds and a maximum chest size of 18.3 inches. On average, Italian foxes weighed 12 pounds (plus or minus 2 pounds) and had chests that averaged 13.8 inches in girth (plus or minus an inch). Dog foxes averaged 13.8 pounds in weight (6,283 grams) and vixens averaged 11.6 pounds (5,265 grams) with average chests of 14.13 inches for dog fox and 13.27 inches for vixens. Chest size did not vary much by region in Italian foxes -- most of the variance was in body length, and weights seem to move up and down on that basis. Italian dog foxes average two pounds lighter than their English kin, and Italian vixens averaged one pound lighter than their English counterparts. Though you would think this might make for an English fox with a slightly larger chest, this does not appear to be the case -- again body length seems to the determinant variable.
