Who has watched their boxer chase a red laser light around the floor??? It is so funny and they chase it so hard (good exercise up and down stairs). Actually Zara will chase any reflection from mirrors, watches etc that happens to move on the floor. Our eldest son (teenager) was trying to talk to his girlfriend lying on his bed. Zara happened to be in there on the bed....and so the little red dot came out to play on his bum. We were killing ourselves laughing at the dog pouncing all over him but I don't think his girlfriend was too impressed, she hung up on him. Who needs to take a boxer on a walk, just get that red laser going and your boxer will happily chase it for hours
