I have plenty of shelter dogs that board with me here at the kennel I manage. None go home worse for wear, trust me. You're helping to resocialize her to a kennel setting, and realize that you guys will come back!!
Can you bring something that smells like home? If you can I would bring a couple of towels or blankets that smell like you. Have them only give her one at a time, and change them out every couple of days, so that she always has something that smells like you and your home (I'd tie them up in their own plastic bags to keep the scent fresh . . . 'cause I'm crazy like that
With only 8 dogs boarding I'm sure they get plenty of special one on one attention, too. She'll do just fine
