If you keep him, you should name him "Santa's Little Helper". Use Santa as his kennel name. Then you can tell your buddies everytime you catch a hog with him that Santa stopped that hog for you. Just saying!
Lol!! Don't know if I will keep him since he had the collar on when he showed up, but the closest house that I know about is about 4 miles down the road. Going to go by there tomorrow and see if they know who's dog it might be. Poor thing had tons of ticks all over him. Give him a bath in dawn clears it right up.
