It's not simple to train a Shih Tzu. They know how to get away with misbehavior by beguiling their owner into forgetting about it.
In terms of compliance, Shih Tzus aren't the greatest, especially when it comes to house training. Call it stubbornness or brilliance.
The Lakeland Terrier is aware that it is much too intelligent for its own good.
This breed's "big dog in a small package" attitude means they require new challenges on the regular or they'll become bored with training.
If training isn't entertaining, Bull Terriers won't put in the effort. The American Kennel Club describes this breed as "a free-spirited individual .
"fun and games" exceeds that to a work ethic." Bull Terriers follow the motto "if it's fun, I'll do it." If not, there's no point.
Not that Bloodhounds can't be taught, but they do need to start learning quickly so they don't get bad habits.
And if a pet owner believes they can untrain a Bloodhound, they're in for a rude awakening. This canine is very resistant to training.
