Angelina Jolie Custody's a Dog Walk in the Park ... When I'm With My Kiddos

Angelina Jolie doesn't seem to be sweating her looming custody trial with Brad Pitt, at least not when she's with her kids ... or some of them, anyway.

Angie was hanging out with three of her children Sunday in Los Feliz -- where she, Shiloh, Vivienne and Knox took their pup for a stroll around the block ... with Shiloh leading the way.

No sign of Maddox, Zahara or Pax here -- the older 3 of the bunch -- but there were certainly no faces of distress on display within the dog-walking group ... in fact, it was nothing but smiles as far as we can see. Even the pooch seemed to be in good spirits.

The happy family outing comes amid a much darker backdrop -- Angelina and Brad are heading to court to decide whether Angie gets sole physical custody of the 6 kids, or if it'll be a 50/50 split ... like Brad wants. Their custody trial is set to begin on Dec. 4, which we're told could take anywhere from 2 to 3 weeks. The judge will sort it all out after that.

There's more to be decided in their bitter divorce -- like property settlement -- which could get ugly considering Brangelina didn't have a prenup when they got hitched.
