Alpaca Health Checks: 5 Things to Monitor Regularly
Alpacas can be surprisingly good at hiding it when something is wrong. A compromised animal may still be seen standing with the herd, grazing alongside its companions and looking relatively normal while an underlying health problem is developing.
For alpaca owners, that creates a challenge: How do you recognize a problem before an alpaca looks obviously sick?
The answer often comes down to knowing your animals, getting hands-on during routine care, and paying attention to small changes over time. You don't necessarily need complicated equipment to catch an early warning sign, but you do need to know what you're looking for.
Here are five essential things to learn to monitor that can help identify a developing problem before it's obvious: behavior, body condition, mucous membrane color, stool and parasite health, and weight or growth.
These are useful starting points for building a routine alpaca health check. Here's what each one can tell you, what to watch for, and when a change warrants a closer look.
1. Learn Your Alpaca's Normal Behavior
One of the simplest ways to recognize a potentially sick alpaca is to know what a healthy day looks like for that individual animal.
Every alpaca has its own personality and habits. Some are first to the feeder, some hang back until the others have eaten, and some have favorite spots in the pasture or particular herd mates they prefer to stay near.
These differences might seem unimportant, but they're valuable information when you're trying to spot a problem.
An alpaca that normally comes running for breakfast but suddenly stays behind is worth watching. The same is true of an animal that becomes unusually withdrawn, spends more time lying down, shows less interest in its surroundings, or stops interacting with its companions as it normally would.
Other changes to watch for include:
Reduced appetite or less interest in treats.
Unusual separation from the herd.
Changes in activity level or alertness.
Less interest in normal routines.
A noticeable change in how the animal moves or stands.
None of these signs automatically means an alpaca is sick. Weather, stress, social dynamics, and other circumstances can affect behavior. What matters is a change from that animal's usual pattern, especially when several changes occur together.
A practical tip: During your daily feeding and chores, take a moment to observe each alpaca individually. Are they all eating? Is anyone hanging back? Does everyone appear alert and move normally?
You may already be doing this without realizing it. Making it a deliberate habit can help you notice changes sooner.
2. Check Body Condition by Touch, Not Just by Looking
If there's one reason visual inspections alone aren't enough, it's fleece.
An alpaca can have a thick, impressive-looking coat and still be losing body condition underneath it. By the time weight loss becomes obvious from the outside, the problem may have been developing for some time.
As shearers, we hear it often: "I didn't realize they were so thin until all that fleece came off." After all, an animal that is growing thin and frail may still look healthy and strong from afar due to a well-grown fleece.
That's why regular hands-on body condition assessment is so important.
Body condition scoring helps you evaluate the amount of tissue and fat covering an animal's bony structures. For alpacas, this involves feeling the appropriate areas along the back and around the ribs rather than relying on appearance alone.
When looking at body condition during an alpaca health check, pay attention to:
The backbone: Can you feel the bony structures easily, or is there a reasonable amount of tissue covering them?
The ribs and surrounding areas: Do they feel unusually prominent?
Changes over time: Does the animal feel thinner than it did during the last assessment?
The goal isn't simply to determine whether an alpaca is thin or fat on one particular day. It's to recognize a change in condition and understand whether that change is appropriate for the animal's age, reproductive status, and overall health.
An alpaca losing condition could have a nutritional problem, dental issues, parasites or another underlying illness. A hands-on assessment won't tell you the cause, but it can alert you that further investigation may be needed.
Body condition scoring is especially useful for breeding females, growing crias, and animals with a history of health concerns. It can also help you evaluate whether your feeding program is meeting the needs of the herd.
If you're new to alpaca body condition scoring, ask an experienced owner or camelid veterinarian to demonstrate the technique and help you establish an appropriate baseline for your animals.
3. Pay Attention to the Color Inside the Eyelids
The inside of an alpaca's lower eyelid can provide an important clue about its health.
Healthy mucous membranes normally have a reddish-pink color. Unusually pale or nearly white membranes can indicate anemia, a condition in which the blood has an insufficient amount of healthy red blood cells or hemoglobin to carry oxygen effectively.
In some regions, one potential cause in alpacas is Haemonchus contortus, commonly called the barber pole worm. This blood-feeding parasite can cause significant blood loss and severe anemia.
The concerning part is that an alpaca may not look dramatically ill in the early stages. That makes monitoring eyelid color a useful addition to routine health checks.
When checking an alpaca, become familiar with what normal coloration looks like in that individual. Look for a noticeable change rather than assuming every animal will have exactly the same shade of pink.
What if the eyelids look pale?
Don't assume parasites are definitely the cause, and don't treat the color alone as a diagnosis. Pale mucous membranes can have other causes, and a veterinarian may recommend blood testing, fecal testing, and a physical examination to determine what's happening.
Marked paleness, particularly when accompanied by weakness, reduced appetite, weight loss, or unusual lethargy, warrants prompt veterinary attention. Severe anemia can become life-threatening.
There are scoring systems designed to help assess anemia risk, including FAMACHA. However, these systems require appropriate knowledge and should be used in consultation with a veterinarian or alpaca specialist familiar with the system.
Checking eyelid color takes very little time, but recognizing an abnormal change can provide an important early warning.
4. Monitor Stool and Take Parasite Testing Seriously
Let's talk alpaca poo... It's more important than you may think. It can tell you something about an alpaca's digestive health, but it doesn't tell the whole story.
Alpacas typically use communal poo piles, which makes it relatively easy to observe changes in fecal consistency. Loose stool, diarrhea, or a noticeable change in an animal's normal output can indicate a problem that deserves attention. However, there's an important distinction: normal-looking stool does not rule out an internal parasite problem.
Some alpacas carrying significant parasite burdens may not have obvious diarrhea or other dramatic digestive symptoms. Conversely, loose stool can have causes unrelated to parasites.
This is why fecal testing is such a valuable part of herd health management.
Why fecal testing matters
Appropriate fecal examinations can help identify parasites and determine whether treatment is warranted. Depending on the suspected problem, testing may involve counting parasite eggs or looking for other organisms.
Results need to be interpreted in context. Not every parasite is detected equally well by every test, and a single negative result doesn't necessarily rule out every possible infection.
If an alpaca is losing weight, becoming lethargic, developing pale eyelids, or showing other concerning changes, your veterinarian may recommend additional testing even if its stool looks normal.
Keeping poo piles cleaned up where practical, managing stocking density, and maintaining a thoughtful grazing plan may also help reduce parasite exposure.
For alpaca owners, the takeaway is straightforward: Watch the stool, but don't rely on it as your only indicator of parasite health.
One of the most serious parasite concerns for alpacas in the Eastern United States is meningeal worm. Regular preventative treatments are incredibly important, but owners should also keep an eye out for warning signs such as stumbling, an abnormal gait, weakness, or difficulty standing. Catching these changes early is critical, as M-worm can cause severe neurological damage and can be fatal.
5. Track Weight and Growth Over Time
Regular weighing is another useful way to catch changes that may otherwise go unnoticed.
An alpaca can gradually lose weight without looking dramatically different from one day to the next. When you see an animal every day, slow changes can be particularly difficult to recognize.
Keeping weight records gives you something more objective to compare. This is especially important for crias. Young alpacas are growing, and monitoring their weight can help you determine whether they're following an appropriate growth pattern. A cria that isn't gaining weight as expected, or that begins losing weight, deserves closer attention.
Weight records can also be valuable for adults. An unexplained decline may be associated with inadequate nutrition, dental problems, parasites, chronic illness, or other health concerns.
How to make weight tracking useful
Whenever practical, weigh animals using a consistent method and record the results with the date and the animal's identification.
Your records might include:
The alpaca's name.
The date and measured weight.
Its age and relevant reproductive status.
Any changes in appetite, behavior, or body condition.
Recent illness, treatment, or other relevant observations.
The important thing is to look at the trend rather than focusing on a single measurement. Small fluctuations can occur, so a change needs to be interpreted in context.
For growing crias, more frequent monitoring may be appropriate than for healthy, stable adults.
If an animal's weight is declining unexpectedly, don't simply assume it needs more feed. First consider whether an underlying health problem could be responsible.
Putting It All Together: Build a Simple Alpaca Health Routine
The best way to use these five indicators is to combine them rather than treating each one as a separate test.
An alpaca that is eating less, losing body condition, and showing pale eyelids presents a different level of concern from an otherwise healthy animal that occasionally prefers to eat last.
Likewise, a cria that isn't gaining weight may need a different assessment from an adult whose weight has remained stable for years.
A simple health record can help you spot these patterns. You don't need an elaborate spreadsheet to get started. A notebook or basic digital record with dates, weights, body condition observations, and notes about unusual behavior can be enough to make changes easier to recognize.
Here's a practical starting checklist:
Observe each alpaca's appetite, activity, and interaction with the herd.
Check for changes in body condition by touch.
Monitor eyelid color for unusual paleness.
Observe stool and follow an appropriate fecal-testing plan.
Record weights, particularly for growing crias and animals with health concerns.
Document unusual changes and follow up rather than assuming they'll resolve on their own.

These checks complement, rather than replace, routine veterinary care. They also don't cover every possible health problem. Changes in breathing, movement, eye condition, urination, abdominal appearance, or other aspects of an alpaca's health may warrant attention, too.
If an alpaca appears seriously unwell, is unable to stand normally, has difficulty breathing, or shows signs of severe weakness, contact a veterinarian promptly rather than waiting to complete a routine check.
The Most Important Part of Alpaca Health Monitoring
You don't have to be a veterinarian to become better at recognizing when an alpaca isn't quite right. You do, however, need to know your animals well enough to recognize a change and be willing to investigate it.
A quick visual check is useful, but it has limitations. Hands-on body condition assessments, regular weight records, attention to eyelid color, and an appropriate parasite-testing program provide additional information that you might otherwise miss.
Most importantly, don't wait for several obvious symptoms to appear before taking a concern seriously. Small changes can be worth investigating, particularly when they persist or occur together.
The more familiar you become with each alpaca's normal behavior and physical condition, the better equipped you'll be to notice when something changes — and to get the right help when it does.
