Welcome new foster dog, Shelly

This is Shelly (the Sheltie?).  She was picked up as a stray.  Was she an abandoned senior?  Did she get lost on her own?  We’ll never know.  She had another rescuer family for a month before being relinquished to Rocky Mountain Collie Sheltie Rescue. 
Poor girl seems lost again.  She scans our faces, trying to understand why everything familiar keeps disappearing.  She looks expectantly at anyone coming into the house – do I know you?  When I put her leash on, she gets happy.  Is she hoping I’m taking her back to the people she left? She wants to be near by – so we don’t get out of her sight and disappear.
She is fitting into the routine.  She enjoys going for rides and walks.  She can really outpace Gracie.  I’m sure I look silly with a sheltie in the lead and another far behind – the leashes and my arms only stretch so far! 
  She doesn’t seem to hear very well – or maybe it’s selective hearing, but I was able to shoot a number of pictures without her noticing my presence.  Then neither clapping, whistling, or stomping on the floor roused her.  Eventually her eyes fluttered open and she saw me waving to her. 
We are still working on getting all the sticks, dirt and mats worked out of her fur.  She doesn’t bark or wag her tail much yet.  I can’t wait to see her personality emerge when she feels brave enough to share her heart again.
