We adopted a 2-year old Cavalier a week ago and she will not walk freely around the house or yard. She has been checked by our vet. She will walk to us if coaxed with treats and will walk back to her bed if we put her down in another part of the house. She has learned to climb 2 steps to get back into the house from the yard. She basically just wants to stay in her bed or on the couch. Any help will be appreciated.
