I got the quintessential lazy bulldog. She's got a routine (she came up with it, I didn't!) - she wakes up everyday at around 7AM, I take her out to potty, then we play for 30 minutes (she's really hyper when she plays - like full-on energy, running full out - and man, she's fast!), then she eats, and she naps. Wakes up around noon, walks around, drinks water, asks for rubbings/treats, then she naps again until my husband comes home from work. Eats her dinner, then we go walking for an hour, then she's done for the day. She's such a slug. LOL! We try to take her out to the park as much as we can to get her more active.
But then, she's a 3-year-old bully, so I'm fairly certain the laziness comes with age.
