Thank goodness you got her back; what an angel to be so honest and call you when she found Bella and that she was safe.
I hope you figure out something else for her when you are gone. Too much can happen.
We have Hawks and Eagles around here that carry off jackrabbits bigger then my girls. One of my friends about 6 years ago now was working in her garden and her doxie puppy was running around playing in the fenced area of her garden and an Eagle swooped down and took her poor baby right in front of her. That incident has always made me so paranoid about letting them run around.
