An Airedale Terrier's farm is sold to city folk. The dog spends his days finding the animals that once lived on the farm and returning them to it. He must convince the city family that they like and need the animals. The father of the new family finally allows all of the animals to stay. Probably published about 1970.
This is Junket by Anne White, published 1955, and charming. Junket likes to have everything Just So.
Wonderful! Thank you so much!
