Tangled frog, rotting leg

[pandamaan01]

I live in the U.k i found a frog earlier with its back leg tangled in netting over my pond. the netting has caused the foot and the part of the leg above the foot to go grey/black. also this part of the leg smells rotting like fishy, i have freed the frog from the netting and its black foot has fallen off, the frog has no control over the black part but seems to have alot of energy and can hop okayish. I have been checking on it until now and i have left it is there anything i should do? to get rid of the rotting part? the part above the rotting part is fine. and has colour. is there anything at all i should/can do?
any replies as soon as possible would be great before i lose it

Frogs lose legs, though they tend not to last long after losing a back leg. Best you can do is let it go. If you're very motivated you could try removing the rotten part of the leg with a sharp scissors or take it to a vet. Many vets in the UK will at least look at wildlife wihout charge, and often treat the animal free too.

I will see if it is alive in the morning..it is very active atm so its should make it throught the night unless somthing catches it...i think bringing it inside would be more stressful than its worth....and i am not sure about how it will heal . :/
