    My puppy steals tomatoes off my tomato plant and eats them – problem is she can’t tell the difference between ripe and unripe tomatoes (dogs are red-green colour blind) so she sometimes eats (or partially eats) green tomatoes. I try to stop her but she knows she isn’t supposed to do it and does it anyway when I’m not looking… I think it’s a game for her because she knows I get annoyed and chase her away from the tomato plant. Silly dog! 🙁

    1. Hahaha! 😀
      It looks like she love playing hide-and-seek with you. Very cute.
