I really hope Toby returns home soon.
When my parents dog bolted, we just drove around and walked the streets calling her and asking everyone. We found her after 2 weeks of frantic searching.
Toby may be hiding so he feels safe, so continue to call him when you are out looking for him.
Of course ring every shelter and rescue in the area.
You must be very worried. Thinking of you and wishing for his speedy return home
