That's awful, I keep reading the news stories about the increase in dog theft but it must be horrible to have it so close to home. I can't imagine what the owners must be going through.
I'm being cautious at the moment, so trying to look out for anyone behaving strangely and making sure I walk where there are lots of other people and in daylight whenever possible. It doesn't sound like that would help if someone was really determined though.
Just terrifying, but thank you for flagging it.
