Honestly, every one of our dogs shows a little of each, depending on the circumstance.
Talking about shedding, I have 2 F1 LD girls that shed oand one F1 GD that sheds...the others are all non shedding.
Some prance like Poodles, but they chew and retrieve like Labs/Goldens.
They are all retrievers, even Poodles...so that is strong in them...and they are all water dogs so they love the water (not the rain though...go figure.

)
They have the Poodle intelligence, all of them...but sometimes a little Goofy attitude comes in too...don't know where that comes from but Doodles are typically goofy.
Some are extremely graceful, absolutely beautiful, like the Poodle...others are a good mix of strength and power...true athletes...
Most people don't consider Poodles as athletic...but they are...and they are water retrievers so they contribute much of what we see as "Lab" traits...
Basically...I think that Doodles are unique...not like Labs or Poodles or Goldens...but just like Doodles!
