My Dog Is 11 Months Old, She Is House Trained But Has Been Goin Lately On The Floor…?

She usually scratches at the door, but we have been keeping my boyfriends mom’s dog for about a week, and lately she has been going on the floor and not scratching. I dont know what to do. we usually put her in her cage and let her stay in there for a little while. I dont know if it is the breed or what is going on with her. She is a jack russell and pointer mix (i think it is jack russell and greyhound but the pound told us pointer). If anyone has any suggestions please help!!
