Yes, Jake loves to chase bugs! I had him outside one evening when the lightning bugs were starting to come out, and he was running and jumping, trying to catch them. I think he did eat one. I was waiting for his poop to be glowing!
Occasionally, we get a fly or moth in the house, and those drive him crazy! He usually does end up getting them though.....so, you might not want to put your money on the fly lol
