Hi there, Our 9 month old female lab quite often sings/whines/whiffles in the evening. This is the same sort of sound she might have made to go out for a wee, but that is not the issue. She also paws me to get my attention even though she has it already and whiffles. I am taking this as a sign that she is tired. She isn't very good at self regulation, in that she goes for hours with seemingly boundless energy, without realising she needs to stop ! Am I missing something or could this be the answer that she is telling me she is tired ? thanks a lot, Andy
