Not sure what is wrong with her she seems so down. She is eating well, drinks lots of water, enjoying her walks and play time. But when we are watching TV and we are all (my husband, Nik and I) sitting on the couch she just stares into space and looks so sad. She seems a little depressed. My husband thinks I am overreacting but I see sadness in her eyes. Has anyone else gone through this before ? Any suggestions ?
