we picked CheddarDog up last night and I loves her. 
It's taken us five months and numerous false starts with interest in dogs that turned out to not be suitable for one reason or another, but we finally got there and she's perfect for us.
We have three cats and a 9 month old DS so knew we might have a wait to find the right dog for us.
So far, all cats are happy to be in the same room as CheddarDog for short periods of time, and CheddarDog shows no signs of wishing to commit felicide so that's good. Under closely supervised conditions DS has been thoroughly sniffed with some associated licked and they seem mutually agreeable to ongoing policed interaction, so good start there.
Housetraining is great - one poo in the dining room 'cause I wasn't watching her carefully enough but she does ask to go out and in her defence did it as close to the back door as possible!
DH slept in the kitchen with her last night and will do so again tonight at least until she settles properly.
Anyone care to guess the cross (photos on my profile - hopefully, if I've done it right!)? The rescue reckons setter cross of some sort - her brother has a much shaggier coat and more setter-ish ears, if that makes sense.
