The two foxes in the first layer are rigged but only for light poses, so don't be too rough with them (those two are only for some art project, but I thought I'd include them anyway). The fox on the second layer is modelled a little more ready for rigging (rigging has been weighted too), so hopefully, you could do poses like running and jumping. I've put the second one into a group called rigged fox, so just append that if you want to use.
Any feedback is welcome, especially as I've never rigged before.
