Hi Fellow Mastiff Parents, We are a little concerned because our healthy, normally high energy 10 month old Cane Corso puppy has started sleeping in until noon for the past 3 days. She went on her first long hike this past President's Day weekend so we initially thought she was still tired from her big adventure. She is eating like normal and her pee/poop looks normal. She still loves to go on her evening walk around the neighborhood. Up to now, I've had to take her to daycare twice a week to play with other pups to tire her out. Has anyone else noticed their puppy becoming much more chill when they hit adolescence? Could she be sleeping more because she's going through another growth spurt? I'm considering taking her to the vet, but I might be overreacting. Thanks in advance for any insight!
