Welcome to YorkieTalk, Sidney and Pepper!! It does take them a little time to get going ... they are so energetic and expend soooo much energy when they
do play that they almost seem to pass out when in reality they are just sleeping!!
Toto, at 16 months, still does that .... but she plays so hard ... and has set herself a routine! If she doesn't get her "naptime" and cuddling around 10AM every morning she is almost "cranky" the rest of the day. Other times she is content to play or nap alone but she wants that particular time for her bonding time I suppose!!
Tell us more about Pepper!!
