I haven’t posted much of Clive lately because he’s been shedding out his winter coat. He does not have mange. He really does shed down to these levels. The areas where he looks hairless are where the fur is about as long as a greyhound’s coat, but it’s much thicker and softer.
This should give you an idea that the red fox is not a bulky, hulking creature at all.
American red foxes seem to be noticeably more gracile than their European counterparts, particularly UK red foxes.
