I thought my puppy hated me. Turns out, I was just keeping her awake for 16 hours straight.
I’m a medical student, and for the first month after bringing my puppy, Luna, home, I was convinced I had adopted a literal demon.
I loved her, but some days the resentment was real. I’d be sitting at my desk trying to get through heavy study blocks, and she would just transform into this unstoppable biting machine. She’d whine, growl, jump, and shred my ankles. I tried everything—free-roaming, giving her more puzzle toys, taking her on longer walks to "tire her out." Nothing worked. She just got more frantic. I was on the verge of tears most nights, thinking I was failing her completely and that my life was officially ruined.
Then, I had a conversation with an experienced rescuer that completely flipped my perspective on puppy biology.
They told me: "Puppies get overtired so easily and become literal land sharks. They need as much sleep as human babies." >
It was a massive lightbulb moment. I realized I was treating her like an adult dog. Because I was home studying, I let her free-roam and stay awake alongside me for almost 15-16 hours a day. Her brain was completely fried and overstimulated, and the biting wasn't aggression—it was a literal toddler tantrum because she didn't know how to turn her own brain off.
That same day, I stopped "going with the flow." I locked in strict, robotic "Reset Blocks". Every 45 minutes to an hour of being awake, she goes into her quiet zone/crate in another room with white noise and a long-lasting chew for a forced 2-hour nap. No exceptions.
The difference? Night and day. The minute I started forcing her to sleep, the 'demon puppy' vanished. She’s calm, she doesn't hit that crazy biting wall anymore, and I can finally breathe and study without crushing guilt.
If you are currently crying on your kitchen floor because your puppy won't stop biting you, please stop trying to tire them out. Put them to sleep! They are probably just exhausted babies who don't know how to crash.
