I've heard they're the best kind, but I'm not so sure. We have one who comes daily and although he's nice enough, he has no qualms about scarfing down our food without an invitation. We don't actually know his name but our non-PC kids have named him (for obvious reasons) Old Fatty.
Cholita loves him and screams with glee when he appears at the back door. "Old Fatty's here! Old Fatty's here!" The other day I was upstairs when Cho joined me in my room. She had guilt written all over her face and I wondered which wall she'd written on this time. She couldn't even keep eye contact. "Mom," she said looking at the floor. "I did something....but I just can't say it." As I encouraged her to spit it out I heard something laboring up the stairs. "I...I....well...." Something was panting its way down the hall. "I let Old Fatty in the house!" Cholita blurted it out just as Old Fatty rounded the corner.
I have 2 large dogs. I often look at our dogs and think it's insane that we let them share our house, but they're ours and I'm willing to claim them. Old Fatty is not ours and based on his girth I doubt he's a stray. The Three Amigos was a nice movie, but the canine version is not something I'm interested in. Old Fatty needs to get his geriatric El Guapo self back home.
P.S. And no, that isn't a third food dish. It's a water dish and two food dishes. Old Fatty seems to think otherwise.
