Predictably I could suggest a nice compact gsp
Can be pocket sized from the right dogs. Never tiny tiny, but bitches are feminine, and they fold up tiny lol. I get Fred AND my other dog in my car easy peasy. My car isn't huge by any means!!!!!
They shed, but no fur balls. Easy to sweep brown stick hairs. No fluff!!
VERY family orientated. They LOVE their people. They like people, but they're not in your face with strangers.
I'd say biddable, as they love to please, but they do have a large streak of stubborn and need an assertive owner who is prepared to train. However, are eager to please, and are clever. And were bred to be extremely versatile. Respond well to positive training, can be sensitive.
Off lead will be as good as the work you put into it. They like to roam and explore, you'll see a brown streak through the trees searching for bunnies and birds, but most will return keenly when trained correctly. Some people have issues, but that's any breed. The stubborn streak is something to be aware of, but deffo not a deal breaker. I was walking with about 10 gsp of varying age last weekend and there were no issues at all in term of recall for any dog
and this was a wide open park, fields, trees and a reservoir!
Longer lived dogs, not brachy.
Not overly barky. Can alert bark, are vocal in terms of Roos and whines and talking to you, but not really yappy dogs. Say like the sheltie rep!
Cons... You can end up with a large dog if you're not choosy.
That stubborn streak
Separation anxiety is possible, they DO love their people.
Energetic dogs, need exercise, stimulation.
Not for everyone
but those who have them love them.
