Yes, he and the chihuahua tag-teamed a little mouse who was trying to live in a bag of mulch. The mouse put up a little bit of fight, scratching Charlie's nose in the process, but ultimately he didn't win.
You should have seen their faces afterwards. Charlie and JJ just looked so pleased with themselves, so (dare I say it?) proud!
They finally got one. After months of tracking and chasing and barking.
Okay, must get back to work now....
