Robbed Again!
Robbed in December last year. Wife was upstairs, heard noise and disturbed someone who ran off with my laptop and cameras.
Some time last night: I haven't had time to recreate as I'm at work but looks like they used a screwdriver to unlock a sliding door to the garage. Took wife's wallet from jacket pocket (jacket worth about 100x contents of wallet) and then took my wife's engagement and wedding rings from the kitchen bench (don't ask).
Strangely left my wallet that contained couple of hundred in cash that was sitting right next to the rings!
I am left with a few options including turning my home into a fortress, so...
What type of dog should I get?

Must be:
Kid friendly. We have a nearly three year old and another due in February.
Smallish. Only have about 50m2 of yard. House has some cat/small dog doors already which would be convenient.
I'm thinking a sausage dog just because I think they look cool/funny, but I hear they aren't kid friendly. Wife is in love with Beagles.
