Using a laser pointer or flashlight to play with your dog can seem like harmless fun, but it comes with several potential dangers, especially to your dog’s mental health and behavior. In the most severe cases the dog becomes obsessed with the light to the point that they can no longer function normally. Even after the dog parents have ceased engaging in laser or light play, the dog is stuck in the mode of frantically looking for the non-existent light. Here’s a breakdown of the risks:

• Frustration and Obsession
  Dogs instinctively chase things they can catch. With a laser, there’s never a “reward” — no physical catch — which can lead to chronic frustration. This is seen with more frequency in the herding breeds. Over time, this can create compulsive behaviors like: 
  • Chasing lights or shadows
  • Staring at walls or floors
  • Pacing or whining when they can’t find the laser
    
    
• Anxiety and Stress
  Constantly trying to catch something that doesn’t exist can trigger anxiety or compulsive disorders, especially in high-drive or intelligent breeds.
  
  
• Redirected Aggression
  Some dogs may become agitated or overstimulated during laser play and redirect that energy with aggressive behavior toward another pet or person nearby.

Here are some better choices for playing with the dog who loves chasing things:

• Use a flirt pole (think giant cat toy) — it mimics the same chase, but with a real, catchable target.
• Fetch with a ball, toy or tug.
• Use sniff games (like hiding treats around the house) or puzzle games to burn energy and keep their mind engaged.

If your dog is already a light chaser, the primary thing to assess is whether it is negatively effecting his quality of life. Not all dogs become compulsive with light chasing. But if your dog spends time looking for non-existant lights, or becomes obsessed when he sees a flash of light, you’ll want to reach out for behavioral help.
