funny puppy

She knows I'm sad. She's been following me around for the past 24 hours, even more than usual. Most of the time, she's really just interested when I'm walking in (or out) of the door, in the kitchen, or getting her doggie food. Last night, she tucked herself so tightly next to me under the covers that I almost wanted to schooch her away a bit...but didn't. This morning, she was on my heels as I stripped the sheets off my bed, standing outside my shower door, and is currently sitting on my feet beneath my computer desk. She's not overly doting, mind you, she's just close. I guess this is what dog people say is them detecting how you feel? Is it sad that I love this dog so much?
