My sweet Mikki had a bad day yesterday. I really don't know why.

I took them out and she wouldn't come in. So I walked to get her. She hunched down when I went to pick her up. I loved on her and brought her in the house. Within minutes I noticed she wasn't under my feet like she usually is. I found her under my chaise lounger in my bedroom. So again I got her and loved on her. I put her down and she ran under the chaise yet again. I have no idea why? I then carried her around for a little while and she was fine. She started playing and bouncing around like usual. Do you think something from her past triggered it? Has anyone else had a pup do this? It was just strange. I have no clue as to what even triggered this. She is just fine today. Back to herself and tormenting Rosie. Haha.
