Is acupuncture painful?

Acupuncture is not painful, or at least we try not to make it painful. A lot of times, if I find a painful area that the pet is sensitive to, I remove that needle to ensure the pet is comfortable. For instance, here's my own dog, and this is the needle. It will simply insert the needle into the pet, push it in, give a little spin to attach to the muscle, and then look. You can see she didn't even flinch.
