Why is my puppy's behavior so inconsistent? Is it a training issue?

Updated On September 23rd, 2025

Pet's info: Dog | Great Pyrenees | Female | unspayed | 9 months and 5 days old | 30 lbs

Why does my puppy act like her normal self (quiet, well mannered, house trained) and sometimes like a completely different dog (barks in the house, chews everything, pees and poops in the house, won’t walk when we’re outside on the leash and instead bites it trying to get off of it, etc) I don’t understand it’s frustrating

Sounds like Rosie needs some training! Puppies need to be taught appropriate behaviors, and I recommend getting her in with a professional behavioral expert to start working on training her. Your vet can recommend one for her.
