Beware of outside world

Ronnie left home yesterday evening for his relieving activities as usual but didn't return home the whole night. I went out to search for him but failed. I was worrying that something bad might happen to him. You see, Ronnie is a very people and animal friendly dog, and abductions do happen quite frequent here. If he is lucky, he might have a new family, and if not, he might end up to be some Vietnamese delicacy. I gave up around twelve midnight and shut the door up before I went to sleep.
Even this morning, Ronnie's still no where to be found before I went to work. Upon returned for lunch, he is already returned but I noticed that he is limping around and obviously moving in pain. You can see from the picture that Ronnie is touching the floor with only 3 limps, the other one is hurting.
Hopefully he will recover soon, and I just do not want to see him getting hurt again.
