How to Read Your Puppy's Body Language

Understanding puppy body language will make it easier to communicate with your pup.

  • Eyes
    Squinting and droopy lids indicate happiness or pleasure, especially during an enjoyable activity like being petted.
  • Ears
    Ears flat against the back of their head is a sign of fear or submission.
  • Mouth
    A partially open mouth with a lolling tongue indicates a happy and relaxed puppy.
