Kay I was just as obsessed with TLK as you, in fact, I still visit this site:http://fanart.lionking.org/ occasionally, and have an account. My favorite characters are Sarabi and Sarafina.
Niño's (pronounced Neenyo) "name" was Nino. (pronounced Neeno) We suspect that at the shelter they were asking the previous owners (an eldery hispanic lady and her adult daughter) what his name was and they thought they were asking them what gender, so they replied "little boy". I liked the name but changed it to Niño. As for next dogs, I have a list several pages long of rregestered names for Dalmatians, with (L) or (B) and (D) or (B) after for liver or black and dog or bitch. I plan on breeding Dalmatians when I "grow up."
My first dog will be a liver male named (hopefully) JLS Mezzo Mixxx after the drink Mezzo Mix. His call name will be Mixer. As for Clark and Layla, Clark is a "super dog" and Layla was named Lady at first. My mom had a golden named Lady before, so I wanted to change it to Delylah, and she said it was too long, so I said I would call her Dilly for short, my mom didn't like it so she suggested Liela, which I absolutly hate as a name, but I loved Layla. My stepdad used to sing her the song.
