My husband and I are both former dancers, with my husband being a former professional classical ballet dancer and now a ballet master.
As for Shrek, that's what his breeder family named him, and since he knows his name we haven't had the heart to change it.
Sylphidesmom, Little Miss Muffett, was also named by her breeder and we to didnt have the heart to confuse the poor girl with a change of names!
My 4 sons ranging from ages (at the time) 15yr to 23yr. were not to crazy about calling out " Come here Little Miss Muffett", "good girl Little Miss Muffett!". But a Moms gotta do what a Moms gotta do. Right?
Roses name had been Rosa, we just modified it a bit.
