Fear, anxiety, and stress are uncomfortable emotions that all pets experience to varying degrees at some point. Typically, these emotions are normal, temporary responses to a perceived threat or circumstance. However, when these responses persist or return, they can negatively impact day-to-day life, and intervention may be required for severely distressed pets. Read on for definitions of these three unpleasant feelings, along with potential causes, signs, and treatment options. Keep in mind that these three states can occur in combination:

  • Fear — A disagreeable emotion that occurs in anticipation of a danger or threat, whether real or perceived, fear typically occurs suddenly, stimulated by a loud noise or sudden touch, for example.
  • Occasionally, fear can persist, and pets can suffer from a profound or idiopathic fear of unknown cause.

  • Anxiety — A person or a pet becomes anxious in anticipation of a future danger or threat. In pets, the most commonly diagnosed anxiety disorder is separation anxiety, which occurs when a pet exhibits destructive or distressful behavior when left alone for long periods.
  • Stress — Stress is a state of emotional and/or physical tension resulting from a particular circumstance. Many pets become stressed in certain scenarios for which they have a negative association.

How can I prevent my pet from experiencing fear, anxiety, and stress?

For many pets, these uncomfortable emotions can be prevented in multiple ways, including:

  • Early socialization — Expose your young pet to as many people, places, and pets as is safely possible. Ensure each experience is positive by rewarding your pet with treats, playtime, or encouraging words.
  • Make the crate a safe haven — Your pet’s crate or enclosure should be a retreat for when she is stressed or needs a break—never use the crate as a punishment tool, or a place she is kept when you leave the home. Encourage your pet to love her crate by adding bedding, toys, and treats, as long as she won’t destroy or ingest the materials.
  • Don’t use force — Learn to read your pet’s cues so you can recognise when she is uncomfortable in a situation. Never force an interaction with another dog or person.
