3-Month-Old Rottweiler Puppy: Weight, Training & Development

At three months old, your Rottweiler puppy is becoming more confident, energetic and curious. You may notice longer legs, rapid growth and much more interest in exploring the world — while teething and puppy biting become increasingly noticeable.

Individual puppies develop at different rates, so avoid judging health from weight alone. If your puppy is younger, start with the 8–12 week development guide.

Training a 3-Month-Old Rottweiler

Focus on:

  • Name recognition
  • Sit
  • Down
  • Come
  • Leave it
  • Drop it
  • Loose-leash foundations
  • Calm handling
  • Crate training
  • Potty training

Keep sessions short. Several two-to-five-minute sessions can be more effective than one long lesson. Our puppy training section has step-by-step plans.

Socializing Your Rottweiler Puppy

Teach your puppy to remain comfortable and neutral around:

  • Adults
  • Children
  • Other dogs
  • Cars
  • Bicycles
  • Household noises
  • Different surfaces
  • New environments

Reward calm observation.

Teething and Puppy Biting

At around this age, chewing often increases. Provide different safe chewing options and rotate them regularly.

Priorities at 3 Months

  • Socialization
  • Recall foundations
  • Bite inhibition
  • Potty training
  • Leash manners
  • Handling
  • Building confidence
  • Learning to relax

Don't rush physical exercise. Mental stimulation and training can tire a young Rottweiler without placing unnecessary stress on their developing body.
