I will just say, leave the front dew claws ON!
My youngster's front dew claws were remove by her breeder (NOT Julia/von Sontausen) and she has "slid out" several times while running around and making hard turns, and I'm wondering if it's because she has no front dew claws. Right now she's recovering from a slight injury to her front leg and has a swollen bump right where the dew claw should be. Who knows, but I wish they'd been left ON.
