I'm afraid I can only offer my sympathy as my Doberman is the same, she is very elderly now and has always done it. She whines because she wants her food, then whines after she has eaten it, whines that she wants to go out then whines when she comes back. All the dogs like to lie down quietly in the evening, she lies down whining.
With her it's not that she's anxious when her head is not permanently glued to my thigh, it's more like she is sulking. She is very needy, very loving and truly devoted but I have 4 other dogs, 2 young children and a husband who all need my attention, so she must take her turn. She just lets me know she's unhappy about it.
