I'm sure my RB Rosie stops in now and then to see me. I thought I heard her bark several different times, I recognized her, and there's no other dogs close that sound like her. I've never "seen" her, but sometiimes while I'm in bed looking at her picture, I feel her come up to the bed and rest her chin on the edge of it like she always did on the couch. I always reach over an pat the air. it's only been 17 months since she was hit. I think since she left in such a hurry, maybe she's still hanging around. Gosh, I miss her. She was my girl.
