Marion, Hi –
Exploring my recent experiences with an injured Hog ( also to it’s back leg )may shed some light..
Apparently, if you have foxes nearby – they won’t necessarily attempt to prey on a fit, fully grown Hog ( I’ve footage on our night cam where the Hog just hunkers down, doesn’t even bother to ball up properly – Fox takes one sniff & moves onto the easy food )
But, sometimes when Hog does balls up & Fox is feeling playful, it’ll wait until it unrolls to make a run for it, only to nip at it’s back legs, for ‘fun’..
The resulting injury will often get infected & whilst ours could shift pretty well on 3 wheels when it needed to.. it’s chances of survival would’ve been hugely reduced..
So, as Simbo says – best get them checked over, if you can, get it up to your local Wildlife Aid centre / hospital – a week in their care, on antibiotics with an MOT & full health check..! & ours is back rummaging around, happily doing that thing that Hogs do!!
Good Luck & let us know how you go?
