UK - After an adopted dog was initially completely quiet, her owners were surprised when she finally came out of her shell and became visibly comfortable.

TikTok user "emiemiozmen" and her partner recently adopted a dog named Mavis from the Romanian animal welfare organization Freedom Angels Romania, as Newsweek reports.

This organization is dedicated to rescuing dogs from Romania and giving them a new life in the UK .

The dog had a tough past. She was found almost dead on the street in Romania, desperately trying to protect her puppies.

When Mavis was finally rescued, she initially remained completely calm. Neither at the rescue center nor at her foster home did she make a single sound, which led her new owners to believe that she was mute.

But after just a few days in her new home, everything changed. The dog began to use her voice - and it turned out that she was not mute at all, but a true "singer".

In a TikTok video, she showed off her musical talent when she joined her owner, who was trying to howl. The four-legged friend enthusiastically joined in and barked with joy. She also enjoyed being cuddled by her new owners while lying relaxed on the couch.

Since then, Mavis has repeatedly expressed her voice, showing how comfortable she feels in her new life.
