Oh Man! I’m so sorry to hear that stuff was stolen, but at least no one was hurt.
Shelties make good alarms. Their bark sounds like a much larger dog (they had to be heard over the sea and wind). If something changes in their vicinity, you will definitely know about it. They aren’t very big either.
Peacocks were also used as alarms for palaces.
Vantid, do be careful about staying at the house. If it hasn’t been done already, call the local police. They usually are willing to swing by that area a bit more often, especially with the holidays
Do check out the pawn shops. You never know what you will find.
Good luck on things being found. I’m on the East Coast so I doubt things will turn up in this area, but I’ll keep my eyes open on ebay.
