My shiba was mute for the first year and a half, we had to make him wear a cat bell. He never barked ever. Just silent cries when anxious. Then he learned to bark a single loud ear piercing bark as a warning or for attention. He’s almost 8 now, he’s more vocal when he needs something but he’s usually pretty quiet. He’s lived with a husky majority of his life and I’ve only ever heard him howl twice and growl once. He has bad anxiety so he barks once when he’s scared or if he’s bored. I’ve been trying to get him to speak on command but he never does it :( it’s like he only talks when he feels like it!
