My dog and I have been alone together for a year. She's pretty bored of me. She still likes me, happy when I come home, but we've kind of hit a rut. Walk once or twice a day, sit on sofa, etc.... eh.
I think if I tried some new games or training she'd be more enthused.
When my dad came to visit it was like the pope had arrived - and she wasn't previously that fond of him!
