Do I have to believe in acupuncture for it to work?

No. Acupuncture is used successfully on cats, dogs, horses and other animals. These animal patients do not understand or believe in the process that helps them get better. A positive attitude toward wellness may reinforce the effects of the treatment received, just as a negative attitude may hinder the effects of acupuncture or any other treatment. A neutral attitude ("I don't know if I really believe in this.") will not block the treatment results.
