Our sitter backed out on us, and we're going on vacation in 3 weeks. There will be 4 dogs total--a cocker spaniel, 2 dachshunds, and a sheltie. Two of them are rescue dogs, and take awhile to warm up to strangers...we need people who can be gentle, yet firm. I don't think I'm really open to kennels. I don't like the idea of them confined all day.
