Hi Donna, just breezing through and I saw this and I readily admit I haven't read the replies so apologies if I am repeating.
My Stella was very much a homebody, she was confident, comfortable and downright joyous in our home and our neighbourhood but outside of her 'comfort zone' she was a neurotic pupcake, heck it was major breakthrough when she decided it was in fact okay to go counterclockwise around the neighbourhood instead of the usual way Going in the car was cause for drippy nose, panting and vomitting, not motion sick but sick from stress over going somewhere.
I spent the first couple years trying to overcome this by carting her all over and working on calming her, then finally figured, you know what, why bother. It was a little more inconvenient to me, I would have loved to 'take her to greyhound events' etc but she was happiest being in her own little kingdom and there was no harm in that so we let her. She had walks twice a day through her neighbourhood where she knew what to expect, where the other dogs were, where the friendly people with snuggles and treats were etc.
I miss that sweet crazy quirky girl though we are head over heels in love with our Jeff Gordon who is much easier going.
