I need a backup care option for my dog and potentially my boyfriends dog incase my room mates and I are gone and I can't take my dog with me.

Barbie - 60lbs 1.5 years old and loves other pets, Barbie is protective of her food but not food motivated, easily gets anxiety and needs to remain on a chain and harness when outside because she can get scared easily (including get scared of me) and want to run away. She loves small children and other pets.
Glacier - 60lbs 2 years old Ausie, much smarter than Barbie but jumps up and tries to give hugs to meet new people. Listens very well. Comes when called.
