There's a thief in my house

To the left you see a picture of sweet innocent 68lb bulldog. Everyone who meets him loves him. He'll sit there and paw at you and give you these eyes that make you think he's the sweetest thing on the planet. But don't let that face fool you. This boy is a thief. Here he is caught red handed with one of Grant's wiffle balls. Niles has managed to chew up at least 10 of them. He has also in the past month chewed up 2 baseballs and a baseball hat. If Grant has a ball in his hand Niles trys to get it. He doesn't want to run, chase it and bring it back to you. He wants to take it from you go lay on his bead and chew it up. He doesn't mess with anything else just baseball stuff. He must love the sport as much as Grant. So here is your warning should you see this lovely creature in your neighborhood hide your baseball gear because he's liable to get it from you.
