- Inconsistent Training: If rules are not consistently enforced, puppies can become confused and exhibit mood swings.
- Separation Anxiety: Being left alone for long periods can cause stress and mood changes.
- Diet and Nutrition: Poor diet or irregular feeding schedules can impact their mood and behavior.
- Fear and Overstimulation: Loud noises, unfamiliar environments, or too much stimulation can cause emotional fluctuations.
- Hormonal Changes: As puppies grow, hormonal changes can influence their moods and reactions.

Why Puppies Don’t Listen
Training a puppy requires patience and consistency. If your puppy isn’t listening, it may be due to the following reasons:
Distractions in the Environment
Puppies are naturally curious, and new sights, sounds, and smells can make it hard for them to focus.
Lack of Training Reinforcement
If training is inconsistent, a puppy won’t learn commands effectively.
Short Attention Span
Young puppies have limited attention spans. Training sessions should be short and engaging.
Fear or Anxiety
If a puppy is anxious or scared, they may ignore commands as a defense mechanism.
Testing Boundaries
Puppies may intentionally ignore commands to test their limits.
