Foxes were dog-like carnivores of woodland and farmland, distinctive for their red-orange coats and their eerie plaintive cries.
In the Second Age, in Númenor, there were foxes in a large number. Their main food were lopoldi, helping the Númenóreans to keep them in order. As they were seldom hunted or because they had enough food with the lopoldi, they never attacked the fowls of the Númenóreans.
In the Third Age, a fox became puzzled at finding Frodo, Sam, and Pippin asleep in a fir-wood on the first night of their journey from Hobbiton, thinking that there was “something mighty queer behind this”. Another fox was encountered by Strider and the hobbits as they hiked through the Chetwood after leaving Bree.
