We are looking after a border terrier while her family sort out some very complicated life stuff(new baby, house move, new jobs, slipped disc- all the usual!) She's been with us all summer, and it looks as if she'll be with us for another couple of months. 
The problem is that we have a very different life style to her home family. They live in a town and she is alone at home during a (short) working day with a dog flap to the garden. She gets regular proper walks and loads of love and attention in the evenings and at weekends- goes to agility and things.
We have a very country life, she just slots in with us walking places, goes out with the horses- comes everywhere with us. My children are older than her home children, and do lots of things she can join in with. And I am beginning to realise that was a mistake. We left her yesterday afternoon, and our neighbours said she howled.
Have we ruined her? What can we do?
