Patterdales do need to have lots of mental stimulation My neighbours patterdale is not 9 years old & still very fit & active.
Patterdales are bred to work, but also to live in family atmosphere & environs They, according to the experts in the breed like Sean Frain, should have very good temperaments
He sounds to me like he needs a home where his brain & body need to be exercised extensively
