for the past week, she's been being more vocal than usual. I want to say she's whining or whimpering but it's a much lighter/ softer noise. She's 11 years old and I havent heard her be this vocal since her surgery a couple of months ago. It's not boredom because she has her walks and doggy play mates. She isn't frightened because she's physically acting quite normal.
What could it be?
