I had my bully until over 12...they sleep all the time. When they are not eating or playing, if they sit around, after a couple minutes thye will always just fall asleep. Mine would sleep on average of 20 hours a day, and deep solid snoring sleep...even when she was younger though more as she got old. The eating I'm not sure about, it's usually a bad sign shen they stop eating. Is she not eating or just troubke with the type of food you're giving, they can be finicky eaters.
ewell it is normal for them to be lazy after all!!!!!!!! Lol with eating. it may have some and they will droll a lot good luck
