It never works. Orion gets so mad when Vegas goes inside her kennel and looks around, but she is always in his pulling his kennel pad in front of the fireplace. She is totally "what's mine is mine and what's yours is mine".
I should try that w spike & sparkles. Omg all they do is fight fight fight. Well not really fight but sparkles like to pick @ Spike's ears and legs & mouth. My poor spike. I just separate them they each go to their crate and fall asleep but maybe I should put them in the same crate like u did w ur babies.
