The "Teenage Regression" is actually harder than the potty training phase. Change my mind

My dog is now 8 months old.

Two months ago, he was perfect. He sat, he stayed, he looked at me with love.

Now? It’s like he has completely forgotten his name. He looks me dead in the eye and ignores commands. He has decided that chewing the baseboards and peeing on bed is a fun new hobby.

Everyone warned me about the puppy blues (2-4 months), but nobody prepared me for the teenage rebellion. Please tell me this ends soon!
