Hugh saw Beru cozying up to him, so he decided to give it a treat. He took out some metal pieces from a discarded technology and gave them to the dog.
Hugh saw that Beru noticed the silver metal before Hugh even took it out. This meant that Beru had a good sense of smell.
It made sense since wolves always had a good sense of smell, and combined with a dog's instincts, almost nothing could hide from it.
"Can you understand me?" Hugh said to the dog.
The dog responded to Hugh by nodding its head and licking Hugh's hand. It seemed that Beru had a smart head that could understand basic human language.
"Then, can you help me find something?" Hugh asked.
With Beru able to smell things from a far away, he would be a good detector for the black cat. Just by himself, it would take a much longer time than he was given.
