I have the lookout also , a single one and the 1 1/2 one so Rosi and Poli fit in it. Well Poli is not use to it and wants to jump, even though i have the harness fairly short he will still try to get to Rosi. Had to pull over the other day to put him back in. When i put them in the same seat then Poli wants to play and Rosi gets mad. Gonna get in a wreck

its aways when we first get in the Truck and go wherever we go, on the way home they are as good as gold together and sleep
