Both of ours came from the shelter with their names. Well Niņo was called Nino by the shelter but my ten year old self figured he was surrendered as Niņo since he had basic obedience training in Spanish so I added the tilde. Eliza was named by shelter staff and my parents couldn't think of anything that fit her that wasn't already super common. They ran all potential names by me to check because I work in a grooming salon and see many dogs a day.

They decided to just drop the E and call her Liza, but my mom's friend called very upset because her daughter's name is Liza and she thought somehow a friend calling her dog the same thing as her child was insulting. So eventually they stuck the E back on.
