Since Lilly hit 5 months old she hasn't been eating the same way she did when she was 4 months old & she sleeps a bit more now. When she was 4 months she ate 3 times a day, now she splits her 2 meals (made it 2 because she wasn't really eating much, but its the exact same amount of food) into 4 small meals.

She's going potty just fine & the same amount as before, nothings really changed other than the eating. She's as active as they come (I swear since she was spayed, she's become more active).

Growth spurt possibly coming up? Could that make her want to split her food, have more energy & nap more? I can't recall when puppy growth spurts happen, I know they grow all the time up until around 8 months or so.
