1. Biting and Nipping
Why it happens: Puppies explore the world with their mouths, and teething makes them extra mouthy.
What to do:
- Redirect to chew toys immediately when they nip.
- Say “ouch!” in a firm but calm voice to mimic how littermates would react.
- Avoid rough play that encourages biting.
🦷 Early correction prevents aggressive tendencies later.

2. Jumping on People
Why it happens: Puppies jump to get attention and greet at face level.
What to do:
- Ignore jumping and only reward calm, four-paws-on-the-floor behavior.
- Teach “sit” as a default greeting behavior.
🐾 Jumping gets less cute when your dog weighs 70 lbs.
3. Pulling on the Leash
Why it happens: Puppies are curious and want to explore fast!
What to do:
- Start leash training early using positive reinforcement.
- Stop walking or change direction when your pup pulls.
🐕 Good leash manners make walks safer and more enjoyable.
4. Resource Guarding
Why it happens: Some puppies feel insecure about food or toys and may growl or snap.
What to do:
- Teach that humans near their bowl or toys = good things (treats, praise).
- Practice gentle exchanges: give a toy, then offer a better one in return.
🍖 Addressing this early prevents future aggression.

5. Inconsistent Potty Habits
Why it happens: Puppies don’t yet know where it’s appropriate to go.
What to do:
- Stick to a regular potty schedule.
- Use a consistent command like “go potty” and reward immediately after.
- Supervise or crate train to avoid accidents.
🚽 Consistency is key to faster housetraining.
