Help me choose a breed

[T00much]

Have been thinking of getting a dog for a couple of years and now seriously considering it so want to do more research on what breed is right for us.

1. size - small to medium (our house isn't massive)
2. exercise - we have a small garden but live round the corner to a big park. We would enjoy taking dog for walks so don't want anything that wouldn't cope with a longish walk (3-5 miles at weekends)
3. We have kids so needs to be good with children (8&12)
4. shedding - as little shedding as possible
5. grooming - nothing that needs to be brushed every day
6. no droolers
7. temperament - friendly, playful but not too crazy and bouncy. One that can be trained to sit/fetch ball
8. Appearance - quite like a natural/scruffy looking dog. I like miniature shnauzers but have read that they can be barky and dislike strangers and a bit moody, unpredictable temperament and prone to blindness. Also like wirehaired datchunds but they are prone to back problems I believe.

Any ideas? I know a lovely cockapoo who ticks all the boxes but I'm worried about dodgy puppy farms

Thank you spider! She did quote "designer breeds" though which was from my post so perhaps it was to both of us?

We have a staffy cross lab.

Lovely with my shy, autistic daughter.
