Cute at Eight Weeks. Less Cute at Eight Months.
A puppy who mouths your hand feels like a love language — until they hit four months old and the teeth get sharper. If you've started wearing long sleeves around your own dog, pulling your hands away during petting, or worrying about your kids getting nipped during play — this is one of the most common calls we get, and it's one of the most fixable.

What Is Mouthing & Nipping?
Mouthing and nipping are not the same thing, and understanding the difference shapes how you address each one.
Puppy mouthing is normal. Every puppy uses their mouth to explore the world. The problem begins when puppies leave their littermates and arrive in a human home, where the feedback system has changed.
Adult nipping is a different conversation. A dog past twelve months who is still putting their mouth on people has carried a puppy behavior into adulthood without the correction that should have shaped it.
A separate but related presentation is herding breeds who nip at heels, ankles, or the backs of legs as a herding instinct. This is more common than many Arizona owners expect.
Partners Dogs has been training Arizona dogs through every kind of mouthing & nipping case for 28+ years. Two locations in Scottsdale and Cave Creek. Lifetime trainer support included with every board-and-train program.
