Words starting with “D” troubles

Words starting with “D” troubles Dog Dad Don’t Doubt Doll Difficult All words that start with the letter D. I’ve been having a hard time with stuttering on words that start with the letter D. I’ve tried slowly articulating, gentle onset, positioning my tongue differently, and nothing has worked. Wondering if anyone has had a similar experience or also struggle with this letter, and if you have any advice! Thank you
