It was so cute! Last night after they had both eaten, our 4 year old lab actually started butt tucking!!! I haven't seen her do that for a long, long time. The puppy was sticking his rear up in the play stance and yipping at her over and over. Then he would bounce around the room and do it again. Kayla got into the same position and for about 5 minutes she PLAYED!! She rolled the ball to the puppy and watched him push it around. Then she would take the ball and butt tuck then do it all over again! Of course everyone was in bed so I'm the only one who got to enjoy it. VERY CUTE AND ENCOURAGING!!!
