Obviously all our Shelties are individuals, but I realized today that Meadow earned unsupervised freedom in the house quite early. Started probably at age 9 months or so, I'd feel OK if I was out front doing something and she was in the house with nobody watching her. I'm talking brief periods, not hours. That is MUCH earlier than I'd trusted other puppies, and she has not let me down. I was out back just now for an hour, Elijah was with me, and Faith is off with my hubby. She just snoozed in one of the beds and didn't bother a thing. What a good girl. Heck, due to Elijah's chewing, it wasn't until he was over 3 years old that I felt I could leave him loose in the house while I ran an errand or something. So what experiences have the rest of you had?
