Yes, I do have 2 opposites for the most part. They do however, exchange rolls and it is quite interesting. There are times that is seems as Roxy is in completed control of TJ (he turns into a whimp). She will be chasing him around and around, attacking him and he is just going along with the whole thing, he rolls on his back so she can play and bite his neck, etc. Sometimes Roxy will get the Nylabone and TJ just lays about 5 feet away just waiting for her to loose interest in it. Sometimes Roxy will grab a toy and prance around and around taunting him and he crawls like a cat after her.
AND then the rolls reverse and POOR Roxy is being attacked by the devil....
