Terrier mix and squirrels

Question
I have a 7 yr old terrier mix, 20 lbs, male who is an extremely capable squirrel hunter. He has taken out 13 squirrels in my backyard in the last year. I have never seen him do this but the corpse winds up on my back lawn. I am not worried about it but should I try and make him stop ?  

Answer
HI PHIL
I WOULD NOT LET MY DOGS KILL ANY ANIMAL.  IT IS THEIR PREY DRIVE TO CHASE THEM, BUT I SCREAM AT THEM DOING THIS ALSO.

WHAT IF THE DOG DECIDES TO KILL SOMEBODYS CAT?
THIS WOULD BE MY CONCERN TO KILLING.?
PERSONALLY, I WOULD STOP HIM OF THIS AND IT MIGHT TAKE A SHOCK COLLAR WITH A REMOTE TO CATCH HIM AND SHOCK HIM TO STOP.  WWW.DRSFOSTERSMITH.COM IS WHERE I BOUGHT A COUPLE MANY YEARS AGO TO STOP MY FIRST TWO SHEPHERDS FROM GOING OUT THE GATE UNTIL I PUT UP FENCING.  NOW MY WEST GERMAN SHEPHERDS WOULD NEVER LEAVE ME.

KIND REGARDS
