Westiepoos are friendly, especially with children and dogs. They appreciate having a playmate. However, they may sometimes get short-tempered, so they are more suitable with older kids who know how to interact and when to stop without hurting them. Younger kids can be with them as long as there's someone to look out for them. They are not that friendly towards other animals, especially small household animals and cats, because they inherited their hunting instincts from their Westie dog parents.
