Acupuncture, the technique of stimulating points on the body by inserting tiny needles through the skin, is being used more frequently to treat animals. Most scientific studies of acupuncture have been conducted in humans. However, the existing evidence in animals led the American Animal Hospital Association and American Association of Feline Practitioners to endorse acupuncture as a treatment option for chronic pain.
Anna Ponce, DVM, and I recently sat down to chat about acupuncture in pets. Dr Ponce provides acupuncture services for dogs and cats and has completed the coursework and examination requirements for certification in veterinary acupuncture. (Interview has been edited for length and flow.)
LAW: How did you decide to start doing acupuncture?
AP: My biggest push to learn acupuncture was having geriatric cats come in with arthritis. Some of them have kidney disease, and there is just no good long-term arthritis medication for these cats. Acupuncture is one of the modalities that has been mentioned, so I decided to explore that avenue and see what I could do to help arthritic cats. And that really opened my eyes to so much more that can be done with acupuncture.
What conditions do you think acupuncture helps the most?
It can really help with any condition: heart disease, kidney disease, coughing, behavioral issues, anxiety. But I think what we know it most commonly for is arthritis.
Which patients do you recommend it for, and how does it help them?
For example, this morning I recommended it for a dog that has arthritis in her knees, elbows, back, and hips. She’s had x-rays, so we know arthritis is there. It took a long time to get her on the right combination of drugs to be comfortable, but she still has off days and I absolutely think she would benefit from acupuncture.
Acupuncture has local effects like decreasing inflammation and pain, and it also helps get the body back in balance. Chronic issues are obviously going to take more time. Acupuncture is not going to make these issues disappear. It doesn’t miraculously make degenerative joint disease return to normal, but it definitely helps the pain and inflammation. [It helps the body release] serotonin, endogenous opioids, and beta endorphins. In my opinion, there’s not a pet that can’t benefit from acupuncture, even if it’s as a preventive measure.
When would you not recommend it?
I wouldn’t not recommend it for just about any patient, but the biggest consideration is whether the patient will tolerate acupuncture. Some dogs and cats fall asleep, they snore, they love their acupuncture, they look forward to it, they’re very relaxed. And then some patients are just not going to tolerate having needles placed in them.
You would not want to put a needle through infected skin. You wouldn’t want to put a needle in a tumor because it would increase blood supply to that area. Certain points are contraindicated in pregnant dogs to avoid inducing labor. And you would not do electroacupuncture [delivery of electrical current through acupuncture needles] in a dog with seizures. But other than that it’s very safe. There’s really not a patient that I would say should not get it. It’s a matter of whether they tolerate it, which I feel most of them do.
How do cats handle it?
I have one cat patient who is very good for his acupuncture. He tells me when he’s had enough needles, so he dictates how many needles he gets. When he starts to meow a little bit and get a little twitchy, we’ve reached our limit, and then he walks into his carrier, lies down, and rests there [with the needles inserted]. Another cat that I treated really enjoyed it and just lay there the entire time, comfortable.
Can you describe a typical acupuncture session?
We use very tiny sterile needles that go in acupuncture points throughout the body. The needles are even smaller than insulin needles. I do a traditional Chinese exam along with my Western exam, make my traditional Chinese diagnosis, and pick acupuncture points based on that. A session might include 5 to 40 needles, depending on what I’m treating; it’s normally 10 to 20 needles. The time patients sit with the needles inserted could be anywhere from 10 to 40 minutes.
Placement of the needles is based on meridians through which qi (chi), or energy, flows and where acupuncture points are located. The strongest points tend to be on the limbs, but those can also be more tender points for dogs and cats. So we often use more points on the back because they’re easier to access and they tend to not be quite as sensitive as the points on the limbs. When a needle’s inserted it causes a de-qi response, essentially a tingling or warming sensation, and sometimes a muscle twitch.
I also use different modalities. Dry needling is insertion of the tiny needles. In electroacupuncture, we hook up electrodes to get higher stimulation. In aquapuncture, we inject vitamin B12 under the skin at acupuncture points to get a longer effect.
How do you integrate acupuncture with Western medicine?
I believe that they complement one another. I think that acupuncture can benefit the patient in ways that Western medicine can’t, especially with end-of-life comfort and pain relief. I definitely wouldn’t throw out Western diagnostics. Bloodwork and x-rays are very important and can help tailor your acupuncture treatment. I think the best type of medicine is an integrative approach, having them work together.
Would you describe your acupuncture training?
You have to be a licensed veterinarian to practice acupuncture [in animals], but you do not have to have a certification in acupuncture to practice it. Being certified shows that you have gone through the training and that you know what you’re doing.
I took a 6-month course through the Chi Institute [of Traditional Chinese Veterinary Medicine] in Florida. The course is 150 credit hours in 5 sessions: 2 online lecture sessions and 3 on-site sessions including lectures and a hands-on lab. After you complete the sessions you take a 200-question written exam and a practical exam. The final requirements for certification are a 30-hour internship with a certified veterinary acupuncturist and submission of a case study of a patient that you have followed for at least 3 months. I’ve done all of the coursework and the test. Once my internship hours are finished and my case study has been approved, I’ll get my certification.

In cats and dogs, chronic (long-term) pain causes subtle behavior changes that can be mistaken for normal effects of aging. Pain can also cause unwanted behaviors like house soiling. Don’t assume that changes in behavior, activity, or mood result from aging, anxiety, or human emotions like resentment or anger. Your pet could be in pain instead.
Arthritis is one of the most common causes of chronic pain in older animals but can go undetected, especially in animals like cats that are biologically programmed to hide their pain. Signs of acute pain (caused by injury) are easier to spot. Whatever the cause of your pet’s pain, recognizing the signs is the first step to helping your pet feel better.
If you think your pet may be in pain, consult a veterinarian. Never treat an animal’s pain with over-the-counter medications, herbs, supplements, or other remedies without checking with your veterinarian first. Many over-the-counter pain remedies, like acetaminophen (Tylenol), ibuprofen (Advil and Motrin), and naproxen (Aleve), are toxic or even fatal to dogs and cats. Your veterinarian can suggest safer and more effective measures for your pet.

Hypertension (high blood pressure) is fairly common in older cats. The condition can cause serious health problems but is treatable. Senior cats and cats with kidney or thyroid disease benefit from routine blood pressure screening.
High blood pressure is silent; it has no symptoms of its own. But high blood pressure damages organs of the body, causing symptoms that cat owners might notice.
In cats, hypertension is usually caused by another disorder. The most common causes in cats are chronic kidney disease and hyperthyroidism (overactive thyroid). Sometimes high blood pressure in cats seems to develop on its own with no known cause, as can happen in humans. Older cats are more likely than younger cats to have hypertension.
Blood pressure measurement
Current guidelines recommend measuring blood pressure in cats in these categories [2,4]:
In cats, blood pressure is usually measured with an inflatable cuff similar to the cuffs used in people (but much smaller!). The cuff is placed around a leg or the tail. During the procedure cats can lie down or sit upright, whichever is more comfortable for them. Most operators try to position the cuff at the level of the heart, but forcing a cat to lie down can cause agitation and raise the blood pressure.
Blood pressure readings are most accurate in calm cats. You might be asked to wait with your cat in the examination room for a few minutes to give her time to settle down and get comfortable. Consider bringing a cat bed, blanket, or towel from home so your cat can rest on something familiar during the procedure. Blood pressure is typically measured several times during each session to account for variation from motion or anxiety. Cats tend to tolerate the procedure well.
A systolic blood pressure below 140 mm Hg is considered normal in cats. (In blood pressure readings like “110/70 mm Hg,” systolic pressure is the first number and diastolic pressure is the second number). A systolic blood pressure of 160 mm Hg or higher indicates hypertension and an increased risk of organ damage.
Veterinarians often measure blood pressure on more than 1 clinic visit before making a definite diagnosis of hypertension. Cats’ blood pressures can vary from visit to visit depending on their stress levels. However, signs of organ damage can confirm the diagnosis and justify starting treatment after only 1 measurement session. Cats with hypertension (or at risk for hypertension) should have blood pressure checks every few months.
The goal of treatment is to reduce the risk and extent of organ damage. The underlying problem causing the high blood pressure is treated at the same time. Most cats with hypertension receive daily oral medication. The dose is adjusted as needed after blood pressure rechecks. Medication is usually effective in reducing the blood pressure, especially if the underlying disease is also controlled.

Chronic kidney disease is common in cats. It can affect cats at any age but is most common in older cats. The disease has no cure. The goals of treatment are to slow the progression of the disease and maintain a good quality of life for the cat.
Functions of the Kidneys
The kidneys filter the blood and excrete waste products into the urine. When the kidneys don’t work properly, these waste products accumulate in the body. The kidneys balance the body’s water level by adjusting the urine concentration. Kidney disease impairs the ability to concentrate the urine and retain water in the body, so animals with kidney disease become dehydrated. The kidneys also help regulate blood pressure, red blood cell production, and acid-base balance.
Signs of Kidney Disease
Kidney disease is already advanced (at least two-thirds of kidney function lost) by the time signs of illness appear. Cats typically have the following signs:
Keep an eye on the size of the urine clumps in your cat’s litter box. Enlarging urine clumps can mean that urine volume is increasing, which is one of the earliest signs of kidney disease. Other disorders (like diabetes) can also increase the urine volume, so larger-than-usual urine clumps warrant a visit to the veterinarian.
As chronic kidney disease progresses, the loss of kidney function leads to further problems:
Causes of Kidney Disease
Acute kidney injury is a rapid loss of kidney function over hours to days. Some of the many possible causes are toxins, infections, and shock. Depending on the cause and severity, acute kidney damage can sometimes be reversed with treatment.
Chronic kidney disease is more common than acute kidney injury in cats. In chronic kidney disease, kidney function gradually decreases over time. The cause is usually not known. The same entities that cause acute kidney injury can lead to chronic kidney failure. Other possible causes are high blood pressure, abnormal kidney development, infection or inflammation of the kidneys, disorders that alter blood flow to the kidneys, and cancer.
Tests are used to diagnose kidney disease, assess the stage of the disease, identify metabolic problems caused by the disease, diagnose other disorders (like thyroid disease) that cats with kidney disease sometimes also have, and possibly reveal the cause of the kidney problem.
Blood tests and urinalysis (analysis of urine) are typically the first diagnostic tests for cats with suspected kidney disease. Blood pressure measurement, urine culture to test for bacterial infection, and ultrasound or x-ray imaging of the urinary tract are also commonly performed for cats with kidney disorders.
Cats with chronic kidney disease benefit from regular testing to monitor disease progression and adjust treatment. In general, these cats should see a veterinarian for blood tests, urinalysis, and blood pressure measurement every 3 to 6 months.
The stage and substage of chronic kidney disease are evaluated with specific tests:
Chronic kidney disease can’t be cured, but it can be managed. The prognosis is variable; some cats can live with the disease for years. If your cat has kidney disease, work with your veterinarian to craft a treatment plan that will give your cat a good quality of life.
Treatment strategies are based on the stage of disease and the individual cat’s needs and may include the following[1,4]:

There’s something special about living with an older dog or cat. After years in the family, senior pets know the household routine and seem able to read our thoughts. And because of advances in nutrition and veterinary medicine, pets tend to live longer than they once did.
Pets’ needs change as they age, and older pets need extra care. Regular veterinary visits and some household adjustments can help keep dogs and cats healthy and comfortable into their senior years.
How old is old?
The common belief that 1 dog year equals 7 human years isn’t really true. Dogs don’t all age at the same rates; small breeds tend to live longer than large breeds. Cats and small dogs are traditionally thought of as senior at about 7 years old (although since they can live well into their teens, 7 years may actually be middle age). Large dogs enter the geriatric stage a bit sooner. Check out these resources for more information:
What to watch for
Keep an eye out for gradual changes over time. Stiff joints, reduced vision, and picky eating are not necessarily normal effects of aging. They are often symptoms of medical conditions that can be treated.
As dogs and cats get older, their risk for arthritis, cancer, kidney disease, thyroid disease, heart disease, and many other problems increases. Watch for symptoms like these:
Dogs and cats should be examined by a veterinarian at least once a year. Older pets may need to be seen more frequently. Many veterinarians recommend wellness checks every 6 months for senior animals. Think of it this way: if 1 dog year really were the same as 7 human years, then an annual examination for a dog would be the same as an examination every 7 years for you and me.
Some diseases progress for a long time before an animal shows any symptoms. Routine diagnostic testing can turn up evidence of chronic disease early in its course, when treatment is most effective. Your veterinarian may recommend these tests for your senior pet:
Preventive health care includes vaccination. Rabies vaccination is required by law in North Carolina for all dogs, cats, and ferrets over 4 months old (for good reason). Dogs’ and cats’ vaccination needs may change as they age, so talk with your veterinarian about immunizations that make sense for your pet.
