The Silver Fox breed was developed by Walter B. Garland and was the third breed to be developed in the United States. Originally named the American Heavyweight Silver, the name was changed to Silver Fox in 1929. Though the black and blue color varieties of Silver Fox were originally recognized, the blue variety was later dropped. The Silver Fox is distinguished by the unique standing fur and silver tipped and white hairs shot throughout the coat. These hairs are evenly dispersed giving a sharp, bright look to the fur. – Maximum weight 12 lbs.
