My first dog!

I rescued my first dog today!! She is a 2 year old jack Russel terrier chihuahua mix, and the sweetest girl ever. Her name was Reign when we adopted her, should I keep it? PLS DROP NAME RECOMMENDATIONS!! She is super jumpy, will jump high up on furniture like a cat 🤣. Only her first day home but she has gone to the bathroom outside four times already and hasn’t gone inside. We were told she is not potty trained, due to living previously with a hoarder who had lots of dogs and let them use the bathroom wherever inside. she is soooo cuddly I’m OBSESSED! Best Christmas gift ever.
