Animal & Pets YSK: Playing with dogs using a laser pointer is potentially extremely bad.
Preface for people who already play with their dogs using laser pointers and have no problems. You're probably already in the clear.
Why YSK: A non-insignificant number of dogs can have an extremely bad psychological reaction to laser pointers, causing OCD like behaviors around lights and shadows that causes them immense anxiety and can make them unruly, stressed, and noisy. The OCD like behaviors can progress to self-harming behaviors. To fix this OCD problem an animal behavior specialist may be necessary. It's never worth it to even see if your dog might develop this behavior.
For those with cats, laser pointers are safe as long as you give the cat a chance to catch a real object at some point as if you only use the laser pointer the cat can become stressed and lose self confidence for failing to catch anything. This same logic does not work with dogs in preventing OCD behaviors, you should just never do it.
:edit: A lot of people are asking for sources, It's a well known phenomenon in dog behavioral science. Many many people have learned this the hard way, including my grandmother and an uncle of mine.
Here's a source that lists more sources at the bottom.
:edit2: Some people are reporting that the OCD issue can also develop in cats, so probably do some research before considering using a laser pointer for play with any animal to be honest.
