Awww, poor Jada. I'm so glad you do regular maintenance and found that though before it got any more infected. Jada is gorgeous no matter what style of hair cut she sports.
My Moka also chews on her beard hair and sometimes has a foul odor despite having very clean white teeth. Guess what I am inspecting closer?
For her its a nervous habit. I'll try to take the little piece out of her mouth, and she'll turn right back around and have it back in there. It's like a pacifier to her. Silly girls.
