I have been feeding and looking after a fox at the back of my garden for last three years since his mother got run over, they came to me as I feed ferral cats and they were stealing their food.

for last three weeks he has been holding up his back right leg, I have given him a small dose of carpodol as thought it might be a sprain but last night he was still holding it up.

Do yo have any ideas of what I should try and do to help him, I have doubled his food in case he has been having trouble getting his own and he can still run around the field

Many thanks

If it is holding the leg up rather than it hanging limply, the chances are it isn't broken. Foxes often sustain injuries which will heal by themselves and I think, as long as there is no swelling or obvious injury/bleeding, I would advise carrying on as you are, monitoring how it is using the leg and supplying supplementary food. If it did need treatment it would mean trapping the fox in a cage trap which is obviously stressful to the fox so we wouldn't advise that unless absolutely necessary. Also, if it is a female with cubs, then we wouldn't want her removed at this time of year especially as she still seems to be coping well.
