In the photo, you can see a black spot on Sioux's side. I thought it was dirt and tried to rub it away, but it turns out to be a permanent spot. A beauty mark, a bigger version of the dark pigment under Cabana's left eye!
I hope Sioux's age and bad hips won't keep someone from adopting her. Senior dogs definitely have a lot going for them! Sioux is so easy and would be a wonderful pet for an older person or a family with young children. I'll post an update when she gets a home, which I predict will be soon!
