#13 Patterndales are easy to train, learning new commands on the fly.
#14 Representatives of this breed are especially in need of timely socialization. If the owner misses this moment, problems cannot be avoided: most likely, the pet will grow up aggressive and nervous.
#15 The Patterdale Terrier should get tired on walks, come home exhausted.
Otherwise, the energy that was not thrown out will be directed to tricks in the house, and the pet is unlikely to listen to the owner.
