Alpha battles here and there, more for about 1 week or 2 right around Nala's 1st b-day. After pulling them off each other and Tonka biting Nala's snout at daycare and leaving a yucky place I called the trainer and she told me to make them sit together if one did not listen correct both then make them do a down stay, for as long as I deemed necessary. It worked now when I notice some tension, I stand infront of them and demand them sit or sometimes go directly down. Ofcourse Tonka and I have been having some female alpha ladder climbing lately too! Over all they are wonderful together though and Tonka takes up for Nala big time and will kiss her when she gets in trouble for chewing.
