Only one question: what characteristics are true for a Wheaten owner?
Ideally, the same. ”Does not yell, does not punish, does not give an inch!”
From our experience, we can come a long way with our Wheaten with love, calm and patience. He then accepts things you could never teach him in a hectic or loud manner. As soon as he hears loud, harsh voices, he either goes deaf and ignores everything, or he obeys and sulks afterwards for good. Both situations are not ideal for a happy human-Wheaten-relationship.
