Neat question....hmmmmm........
Amos would absolutely be red, he is almost nine and has the energy of a pup, loves to run, and run..and is a quick learner!
Bailey would be pink, she is lady like, mellow, sweet and LAZY!(sorry Bay)
Stella would be purple, she is royalty, she wants things her way, and does not go with the flow!
Otis would green like nature, very earthy and loving, a real mush mellon! Terri
