The secret of the grumpy dachshund

Young witch Lotti has become friends with her familiar, a dachshund named Sophie, and now can hardly imagine her life without the dog who loves coffee, chocolate, and grumbling. It seems that nothing can come between their friendship... except jealousy. Lotti decides to help a rabbit. It is being sold in a pet store, sitting in a cage that is too small and looking very sad. Lotti would buy it, but she doesn't have enough money, so the girl decides to do a little magic for the creature. Without Sophie, she can't handle such spells, but the dachshund refuses to do anything. She thinks that Lotti wants to get another familiar, this very rabbit. How can Lotti convince Sophie and explain that she wouldn't trade her dog for anyone in the world, but not helping others when you can is simply wrong?
