My Corgi "Chewy" is now 1.5years old and I leave her at my backyard when my hubby and i go to work. we don't come home until 9-10hrs later. When we come home, she does fine, she plays, eats, happy, we take her for a walk in the park & etc... around 9:30 -10pm is when we lock her in her crate and lately, she's been banging on the crate all night trying to come out. She goes crazy even after we tell her "NO!" many times. I don't know why she's behaving like this. Does anybody have similar experience?
