So, I've recently-ish gotten an Italian Greyhound. She's just turned one. A couple of times now she's peed on my dad's bed (while having access outside). If she's allowed, she would sleep on my bed, never anyone else's, and she has never peed on my bed. She's just now peed on my (older) brothers bed (who's door is usually closed.) Does anyone have any ideas as to why she is doing this?
