As an alpaca owner, it is important to closely monitor the health of your animals. Alpacas are prey animals by nature and tend to hide signs of illness until they are quite severe. Being attentive and watchful for subtle changes can allow you to identify emerging health problems early and seek treatment promptly. This helps provide the best chance of recovery and prevents minor issues from escalating into serious illness.
In this comprehensive guide, we will cover the most common signs of illness in alpacas and what to look for in order to identify health problems as soon as they arise.
Weight Loss or Poor Body Condition
One of the first signs that an alpaca is unwell is weight loss or deterioration in body condition. Alpacas should have rounded, full bellies and maintain good muscle mass over their vertebrae, hips, and shoulders. Here are some visible indicators of weight loss or poor condition in alpacas:
- Prominent vertebrae and ribs becoming visible
- Hip bones jutting out
- Loss of muscle mass over the shoulders
- Noticeably sunken flank area behind ribs
- Loss of fat pad at the tail head
- Thin or emaciated appearance
Weight changes are most visible when looking from the side and above. Weighing alpacas regularly with a livestock scale can help detect more subtle losses. Sudden or rapid weight loss can signal an acute illness while gradual dropping condition may indicate a chronic health problem.
Causes of Weight Loss
Some potential causes of weight loss in alpacas include:
- Infectious diseases such as parasitism, Johne’s disease, or Caseous lymphadenitis
- Dental issues making it painful to chew and eat
- Gastrointestinal conditions such as ulcers or malabsorption
- Cancer or other internal organ diseases
- Stress, depression, or loneliness leading to reduced appetite
- Insufficient nutrition or poor quality feed
Rapid weight loss especially warrants immediate investigation to diagnose the underlying cause. Consulting a vet and having diagnostic testing done is advised. Treatment of the underlying condition along with improved nutrition can help regain condition.
Changes in Behavior or Activity Level
Alpacas are creatures of habit and generally maintain consistent patterns of behavior
. Significant changes in normal habits or activity levels, especially lethargy or isolation, can indicate an alpaca is not feeling well. Here are some behavior changes to watch for:
Lethargy, Depression, or Low Energy
- Unusual lack of interest in food
- Standing alone, separated from the herd
- Appearing generally slow, tired, or weak
- Disinterest in surroundings or interactions
- Reluctance to get up; prolonged recumbency
Unusual Vocalizations
- Frequent, strained, or painful sounding cries
- Grinding teeth or other abnormal oral noises
- Alterations in humming or clicking sounds
Changes in Posture
- Holding head tilt or turned to one side
- Arching back or stretching neck upwards
- Sitting or lying down much more than usual
Loss of Appetite
- Lack of interest at feeding times
- Not chewing cud for long periods
- Weight loss (as covered above)
Strange Gait or Trouble Walking
- Limping or holding one leg up
- Splaying legs outward or difficulty standing
- Stumbling, loss of balance or coordination
- Swaying abnormally as walks
- Resisting movement or reluctance to get up
Increased Time Lying Down
- Prolonged periods of recumbency
- Slow to rise or spends minimal time upright
- Lying down at unusual times of day
Social Withdrawal
- Isolating from the herd
- Not seeking companionship or interactions
- Rejected from herd and forced to stay alone
Agitation or Restlessness
- Excessive pacing or getting up and down
- Abnormal lack of sleeping
- Signs of stress, anxiety, or pain
- Irritability or aggressive behaviors
Pay close attention to when these behavior changes arise and how long they persist. Acute alterations warrant prompt veterinary investigation. More mild or intermittent signs may still benefit from having a vet visit to examine your alpaca.
Changes in Eating and Drinking
Alpacas are grazing animals, spending much of the day eating. Digestive issues are one of the most common health problems, so monitoring appetite and water intake is important. Here are some abnormal signs to watch for:
Decreased Appetite or Disinterest in Food
- Not eagerly eating morning feed
- Picking at hay; taking only a few bites
- Unfinished meals remaining in feed bowl
- Loss of appetite for favorite treats or supplements
Difficulty Chewing or Swallowing
- Dropping partially chewed food (known as quidding)
- Food falling from mouth while eating
- Excessive salivation or drooling
- Weight loss and change in fecal pellets (covered below)
Increased Water Intake
- Drinking significantly more frequently or for longer periods
- Hanging around water trough longer than usual
Decreased Water Intake
- Visiting water trough less than normal
- Passing dark yellow or concentrated urine
Regurgitation
- Throwing up partially digested food
- Undigested food visible in vomit
Monitor grazing time, observe feeding closely, and track water consumption daily. Any abnormalities or changes warrant a veterinary exam to determine the underlying cause.
Change in Feces
Alpacas’ digestive system and feces provide many clues to their health status. Always check and note the quantity, consistency, and color of manure daily. Here are some abnormal changes to watch for:
Diarrhea
- Loose, watery, or unformed feces
- Excessively mushy manure piles
- Soiling around tail and hindquarters
Constipation
- Hard, dry, or impacted feces
- Difficulty passing manure; straining
- Decreased manure pile size
Color Changes
- Unusually dark or black feces
- Gray, clay-colored, or pale manure
- Presence of blood, mucus, or stomach contents
Parasites
- Visible worms in manure or around anus
- Grinding teeth from discomfort
- Rough, dull coat
Diarrhea and constipation can alternate as colitis episodes occur. Repeated changes in fecal consistency warrant laboratory fecal testing and veterinary advice. Parasites should be treated promptly under a vet’s guidance.
Signs of Pain, Discomfort, or Strain
Prey animals like alpacas instinctually conceal signs of pain or injury to avoid appearing weak. However, subtle expressions and postural changes can indicate discomfort. Be vigilant for these signs:
Facial Expressions
- Flattened or curled back ears
- Closing eyes for prolonged periods
- Grimacing or strained appearance
Physical Reactions
- Arching back or stretching neck upwards
- Rapid, heavy breathing or panting
- Grinding teeth
- Groaning, crying, or straining sounds
- Agitation, kicking, or biting at body
Posture Changes
- Abnormal sitting or lying positions
- Shifting weight frequently from side to side
- Reluctance to move or get up
- Restlessness, anxiety, or inability to get comfortable
Response to Palpation
- Flinching, withdrawing, or aggression when touched
- Sensitivity or reaction to areas of body being pressed
- Guarding or reacting to one side more than the other
Let your vet know if you observe any of these subtle indicators of discomfort. Pain and injury often manifest as changes in behavior, posture, gait, and temperament. Veterinary examination can assess the cause and allow for appropriate pain management.
Signs of Problems in Specific Body Systems
Many health issues arise in particular organ systems. Here are some red flags to watch for:
Respiratory Signs
- Breathing heavily or faster than usual at rest
- Flared nostrils or exaggerated chest movements
- Audible wheezing, coughing, or nasal discharge
- Mouth hanging open or head extended to aid breathing
Cardiac Signs
- Very rapid or labored breathing
- Pale or bluish gums
- Weakness, trembling, or collapse
- Swollen belly or limbs
Reproductive Signs
- Lack of heat cycles or pregnancy in females
- Changes in mammary glands
- Swollen testicles, penile injuries, or unusual discharge in males

Diagnostic Testing Options
Doctors have a number of diagnostic tools to identify the root cause of alpaca health problems. Some options include:
- Physical Exam and History – The veterinarian thoroughly evaluates vital signs, body condition, coat, gait, rectal temperature, abdomen, and overall wellbeing while gathering a history of symptoms.
- Bloodwork – Blood tests assess organ function, identify parasites and infections, reveal vitamin deficiencies, and provide other insights into overall health.
- Fecal Exam – Microscopic evaluation and cultures identify intestinal parasites and overgrowth of bacteria or protozoa.
- Biopsies and Aspiration – Collecting and analyzing tissue or fluid samples can diagnose masses, organ function, and fungal or bacterial diseases.
- Ultrasound – Imaging internal organs aids in evaluating digestive issues, pregnancy, urinary problems, heart health, and abdominal disorders.
- Endoscopy – Allows visual examination of nasal passages, throat, stomach, intestines, and airways using a flexible camera scope.
- Radiographs – X-rays provide views of bones, lungs, and abdominal organs to identify issues like dental problems, pneumonia, or organ enlargement.
Discuss all options with your veterinarian and pursue diagnostics as recommended to direct your alpaca’s treatment effectively.
How to Prevent Illness Promptly
The best approach is promoting wellness proactively to prevent health problems from developing. Recommended prevention strategies include:
- Maintain a low stress environment and stable herd social structure
- Quarantine and test new arrivals before introducing them into your existing herd
- Deworm at least twice yearly and avoid overcrowding pastures
- Shear annually to allow for seasonal weather variations and check skin closely
- Feed high quality hay and natural grazing; avoid sudden diet changes
