I have reduced mass a lot from what I had before. Now:
body = 1.0
each leg part (upper/lower) = 0.5
head = neck = 0.0001

I have set maxForce = 1200

Doggy doesnt flip over. It falls down straight (like sitting down), so its on
the body instead of legs and legs moving in the air (of course attached to
body). Do you think that mass = 1.0 is too much for me. hmmm. let me try and
reduce that. I will let you know if it effected.
