Cleo Dog

What rhymes with Cleo female names.?
I have a new dog, his name was Cleo about a year. My brother and father are the names of Leo .. I have really wanted to change his name, but keep it close. Dogs do not recognize the sounds and tones of words, just about anything fit. I have two cats, Peter and Lola I like human names for my animals …. any suggestions?
Rio de Janeiro, as in "Her name is Rio." There are not many female names ending in "or" because they tend to have a men's final in Spanish and Italian. But you can use something that has been men and do well by the name of women (Neo / neyo or something). Or you could go with somethign but clearly CLEA about women, such as (ah Clee) or me or leah …
