yes..dog food! i have rescued many hedgehogs in my time..one, when i was out walking my dogs and there he was lying in the middle of the path..i almost stepped on the poor little thing! it was spring and had just woken up and was very weak and underweight. i was told by a vet to feed him a bit of dog food and he pigged out on about 3 bowls full! and suddenly came alive again and was running round and round the carrier i had put him in. I then released him back to the place i had found him and he scuttled off into the long grass.
