Is Acupuncture Effective in Pets?
Dr. Eric Barchas, DVM

25143_1198901098Acupuncture has been used in humans for at least 1000 years. It now is widely used in animals as well.

Some of my acquaintances from veterinary school perform acupuncture on animals. They are convinced it is effective. They also make a tidy profit from performing the procedure.

To this day, nobody can prove, nor disprove, that acupuncture truly works. Some studies have shown significant effects when acupuncture is used in specific circumstances. Others have shown no effect whatsoever. Many studies have been equivocal: they provide some evidence that acupuncture might be effective, but they don’t prove it conclusively.

Acupuncture therefore is perennially controversial.

The theory behind the traditional practice of acupuncture involves the flow of energy through the body. Our current understanding of anatomy and physiology does not back that theory up. Other theories of acupuncture state that the procedure leads to the release of endorphins (morphine-like chemicals that occur naturally in the body).

Plenty of people are willing to offer testimonials in favor of the effects of acupuncture in humans and animals. Many such people may comment on this post. But, as any student of science or medicine knows, personal testimonials are notoriously unreliable sources of information. They are highly subject to bias and confounding factors. Honest-to-goodness scientific studies are needed to verify clinical claims. When it comes to acupuncture, such studies generally have yielded conflicting results.

Some experts believe that acupuncture works mainly through the placebo effect. Acupuncture is not alone in this regard: some recent studies have suggested that Prozac’s effect in many people may be spurious.

Other experts point to some well run clinical studies that show significant effects from acupuncture when it is used to treat specific syndromes. In all, neither side can prove conclusively that it is right.

I personally don’t care why or how a treatment such as acupuncture may work. I care only whether it works. The information I have seen to date is equivocal.

I was therefore excited by a grippingly titled article in the May 1, 2009 Journal of the American Veterinary Medical Association (JAVMA): “Effects of adjunct electroacupuncture on severity of postoperative pain in dogs undergoing hemilaminectomy because of acute thoracolumbar intervertebral disc disease.”

The paper discusses the study of a special form of acupuncture used to treat pain in dogs recovering from back surgery. From the article:

Conclusions and Clinical Relevance–Results provided equivocal evidence that [acupuncture] might provide some mild benefit in severity of postoperative pain in dogs undergoing [back surgery] because of [slipped discs]. (J Am Vet Med Assoc 2009;234:1141-1146)

In other words, the study determined that acupuncture might have sort of worked to reduce pain after back surgery. But the study authors weren’t sure.

Suffice it to say that I was disappointed by the results of the study. I have been waiting my entire career for some hard science to back up or refute the practice of acupuncture. This study, like so many before it, did neither.

At this point, the only answer I can give to the question posed in this post’s title is I don’t know.

Is Veterinary Acupuncture Effective?
Dr. Eric Barchas, DVM

dog-acupuncture.jpgI have a 7-year-old healthy Old English
Bulldog but being that he is getting a little
older I was thinking of bringing him to get
acupuncture. He is a big part of our family and I
want him to have the most relaxed and happy life a
dog could have. My question is, do you have to
wait until there is an actual problem to do
acupuncture? And my other question is do you see
anything wrong with acupuncture?

Acupuncture is a perennially controversial topic in veterinary medicine. Some vets tout acupuncture as a cure for everything from depression to kidney failure. Others think that the entire practice of acupuncture is a sham.

Which side is right? Probably neither.

The acupuncture advocates generally have failed to do something very straightforward: prove that acupuncture is effective for the many ailments that it supposedly treats. This is a very glaring omission in my mind. As I have discussed in my other posts on evidence-based medicine, it is very simple to prove that a medical technique works.

For instance, a study to test the efficacy of acupuncture for the treatment of feline kidney failure would be very simple to run. Take two groups of cats with comparable kidney function. Have a trained veterinary acupuncturist perform acupuncture on members of one group for 30 minutes apiece twice weekly. Have a different person gently pet members of the other group for 30 minutes apiece twice weekly. Do not tell the cats’ owners which group their cats belong to. Compare outcomes.

It’s really that simple. But for some reason these studies are very rarely performed. This makes me wonder: does veterinary acupuncture work strictly by the placebo effect?

Maybe not. A few well-designed studies have shown that acupuncture can relieve pain in some instances. It also can lead to release of endorphins. Endorphins relax the body. So there is a chance that taking your dog to an acupuncturist will, in fact, help him to lead a relaxed and happy life.

Although the jury is still out on the debate over acupuncture, one thing is certain. There are a lot of scammers out there practicing veterinary acupuncture with little or no training. These people will waste your money in the best case. In the worst case, they may harm your dog.

In my opinion there is nothing wrong with taking your dog to an acupuncturist. But be careful to check the credentials of the person who will perform the procedure on your pet.
