So far.. (I've had her nearly 8 weeks)
Puppy pads.. not used (or needed) a single one.
Nice dog bed. ..she likes a cool spot on the floor preferably under the sofa.
Crate (see above)
Expensive harness that wasn't very comfy for her (now has a perfect fit one which is brilliant)
And so many toys that I am embarrassed to count them
To be fair we rotate them so she doesn't get bored.
I keep seeing things in pet stores and think 'ooh we MUST have that!' then she ignores or is blissed out playing with an empty kitchen roll tube...
