A glucose curve is useful only when you read it as a pattern, not as a diagnosis. For a dog or cat, start with how the data were collected, how complete the record is, when highs and lows recur, and what was happening with meals, exercise, illness, and medication. A continuous glucose monitor (CGM) report adds standardized measures such as time in range, time below range, time above range, and variability. Those measures can organize a conversation with your veterinarian, but human CGM targets are not veterinary prescriptions and an isolated curve should never be used to change insulin or another treatment.
What is a glucose curve?
A glucose curve is a graph of blood-glucose readings over time. In veterinary practice it may come from periodic blood samples collected at home or in a clinic, or from a sensor that records glucose throughout the day. The horizontal axis is time; the vertical axis is glucose concentration, usually in mg/dL or mmol/L.

A single reading answers “What is the glucose now?” A curve asks “How does glucose behave across the interval?” That difference matters. A pet can have a reasonable-looking average while still having repeated highs, lows, or large swings. Conversely, one unusual point may look alarming but be unimportant if it does not recur and the record is incomplete.
CGM values measure glucose in interstitial fluid rather than directly in blood. During a rapid rise or fall, the sensor reading can lag behind blood glucose. The international consensus on CGM interpretation also notes accuracy limitations and delays during dynamic changes; interpret readings according to the device instructions and your veterinarian’s advice (International Consensus on Time in Range).

How much CGM or curve data is enough?
Check data coverage before interpreting any pattern. Record the number of days represented and the percentage of time the sensor was active. The International Consensus on Time in Range uses 14 days with at least 70% active data as a useful standard for routine interpretation. The American Diabetes Association (ADA) describes a 10- to 14-day assessment with CGM wear of 70% or more as useful for assessing glycemic status (International Consensus; ADA Standards of Care—2026).
Those figures are guidance for routine human CGM review, not a universal rule for every pet or every clinical question. Your veterinarian may need a shorter record to answer a specific question, or a longer and more targeted review to investigate intermittent lows, suspected sensor gaps, or highly variable control. A report with many missing hours can fail to show what happens overnight or after a meal.

- Days represented: note the start and end dates, and whether the pet wore the sensor continuously.
- Active time: identify gaps caused by a loose sensor, scanning failure, transmission problem, or removal.
- Context: record meal times, medication or insulin times and doses, vomiting or diarrhea, unusual activity, stress, and illness.
- Comparability: when comparing two periods, use the same units, similar coverage, and similar daily routines.
Which parts of a CGM report should you read first?
Read the coverage summary, time-in-range summary, and the standardized daily profile together. Human reports often use an Ambulatory Glucose Profile (AGP), or a comparable device report. The consensus recommends common metrics and visualizations so clinicians and patients can discuss the same information (International Consensus on Time in Range).
Coverage and dates
Confirm that the report covers the period you think it does. A curve that begins after breakfast every day cannot answer what happens before breakfast. A missing overnight section cannot rule out nocturnal lows. Write down the sensor’s active percentage and the times of major gaps before drawing conclusions.
Time-in-range bands
Time-in-range (TIR) is the percentage of readings in a defined glucose band. Time below range (TBR) and time above range (TAR) show how much time falls below or above that band. Extreme-low and extreme-high bands are often reported separately. Together, these measures show distribution, whereas an average alone can conceal both highs and lows.

AGP or the daily profile
The profile overlays days by clock time. A narrow band means readings were similar at that time; a wide band means the pet’s values varied substantially. Look for repeated features at the same clock time rather than reacting to one isolated trace. The profile does not tell you why a change occurred, so use the diary and clinical history to supply context.

TIR is time spent inside a specified glucose interval. TBR and TAR are equally important: improving TIR by creating more lows is not an improvement. Always read the three measures together and check the exact thresholds used by the report.
For many nonpregnant adults with type 1 or type 2 diabetes, consensus examples use 70–180 mg/dL (3.9–10.0 mmol/L) as the target band. An ADA report infographic gives example goals of more than 70% TIR, less than 4% below 70 mg/dL, and less than 1% below 54 mg/dL; it also displays time above 180 and above 250 mg/dL. Each 1% of time is approximately 15 minutes, and a coefficient of variation of 36% or less is an example variability target (ADA Standard CGM Report).
These are examples for defined human populations. They are not safe target ranges for a dog or cat, and they should not be converted into an insulin dose. Veterinary targets depend on the animal’s diagnosis, treatment, symptoms, concurrent disease, and the meter or sensor used. Ask your veterinarian which bands and safety thresholds apply to your pet.
| Metric | What it describes | How to use it in a veterinary discussion |
|---|---|---|
| TIR | Percentage of readings in the report’s target band | Ask whether the chosen band is appropriate for this pet and whether coverage is adequate. |
| TBR | Percentage of readings below the target band, including any extreme-low band | Prioritize repeated or prolonged lows for prompt veterinary review. |
| TAR | Percentage of readings above the target band, including any extreme-high band | Look for recurring timing and possible links to meals, medication timing, illness, or missed treatment. |
| Coefficient of variation | A standardized summary of glucose variability | Use it to discuss swings, but do not treat a human threshold as a pet target. |
| Mean glucose or GMI | An estimate of overall exposure from CGM data | Use as a summary alongside the curve; it does not show when highs or lows happened. |
How do you recognize a meaningful pattern?
Ask whether the rise or fall repeats, when it occurs, and what was happening immediately beforehand. A recurring pattern across several comparable days is more informative than a single excursion.

After-meal rises
A rise after eating can reflect the meal’s composition and size, the timing or effect of medication, delayed stomach emptying, stress, or illness. Mark the meal’s start time and compare similar meals on several days. ADA 2026 guidance says postprandial glucose measurements should generally be made 1–2 hours after the beginning of a meal (ADA Standards of Care—2026). That timing describes a point measurement; a CGM curve can show the full rise and recovery. For a pet, use the timing your veterinarian recommends rather than applying a human schedule automatically.
Overnight or early-morning changes
Repeated overnight lows, dawn rises, or a drop followed by a rebound deserve clinical review. First check whether the sensor was active during those hours and whether the pet ate, vomited, exercised, or received medication at an unusual time. Do not assume a named human pattern explains a pet’s curve.
Activity-related changes
Exercise can lower glucose during activity or later, and the size of the effect may vary from day to day. Record the type, duration, and timing of walks or other exertion. A repeated post-activity low is information for the care team, not a reason to independently change treatment.
Illness and stress
Pain, infection, dehydration, vomiting, diarrhea, and clinic stress can alter glucose. Note symptoms beside the curve. A sudden change that coincides with illness should be interpreted with the pet’s examination and other tests, not as a stand-alone CGM diagnosis.
Medication timing
Place each dose on the timeline and look for repeated relationships between treatment and later highs or lows. Never increase, decrease, delay, or repeat insulin because of one graph without veterinary instructions. If the curve shows a possible low and the pet is weak, disoriented, shaking, seizing, collapsed, or unable to eat, follow the emergency plan supplied by the veterinarian and seek urgent care.

How should you compare two glucose curves?
Compare like with like. Use the same glucose units, report thresholds, time span, and metric definitions, then check whether sensor coverage and daily circumstances were similar.
- Align the periods. Record each report’s dates, days represented, and active-data percentage.
- Compare TIR, TBR, and TAR together. A higher TIR is not automatically better if TBR also increased.
- Check extreme bands. Note time in the report’s most concerning low and high categories.
- Review the clock-time profile. Identify whether changes cluster after meals, overnight, around activity, or after treatment.
- Compare variability. Use the report’s coefficient of variation or equivalent measure, while remembering that mean glucose and GMI summarize exposure rather than timing.
- Explain context. Mark changes in food, routine, medication, illness, weight, or sensor type before attributing a difference to treatment.
A1C and CGM-derived measures are complementary and may not match exactly. A one-time glucose reading should not be compared with an average as though they were interchangeable.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What can make a glucose curve misleading?
- Incomplete data: missing hours can hide a recurring low or high.
- Sensor lag: during rapid changes, interstitial readings may trail blood glucose.
- Device limitations: accuracy varies by device and situation; follow the manufacturer’s instructions and veterinary advice.
- Unusual days: illness, fasting, stress, travel, or atypical exercise may not represent the usual routine.
- Wrong target band: a human report range may be inappropriate for a pet.
- Overinterpreting one point: confirm a suspected pattern with repeated observations and clinical context.
If a sensor value conflicts sharply with how the pet looks or behaves, follow the device instructions for confirmation and contact the veterinary team. Symptoms of a possible emergency take priority over an attractive-looking graph.

Bring the complete report, not only a screenshot of the most dramatic section. Include the sensor dates, active-data percentage, glucose units, medication schedule, meal and activity log, symptoms, and any confirming blood measurements requested by the clinic.
- Circle repeated highs, lows, or rapid swings and write the clock time beside each.
- Separate a recurring pattern from an isolated event.
- Ask which glucose bands are appropriate for this individual pet.
- Ask whether more data, a different measurement method, or a supervised curve is needed.
- Agree in advance on what to do for a low reading, a sensor failure, vomiting, or inability to eat.
The ADA describes CGM as useful for understanding responses to meals, physical activity, and medication changes, but its 2026 recommendation still frames glycemic assessment as a combination of A1C and/or CGM metrics rather than a single number (ADA Standards of Care—2026). In veterinary care, the same principle applies: the curve is a shared decision-making aid alongside examination, history, and other tests.

Can a glucose curve diagnose diabetes in a pet?
No. A curve can reveal glucose behavior and help a veterinarian investigate diabetes or treatment problems, but it does not independently establish a diagnosis, predict a complication, or dictate a dose. Diagnosis and treatment decisions require the pet’s clinical signs, repeated measurements, laboratory testing, and veterinary interpretation.
How we selected the interpretation framework
This framework uses the standardized CGM concepts in the International Consensus on Time in Range, the ADA Standards of Care—2026, and the ADA standard CGM report: data coverage, TIR/TBR/TAR, variability, daily profiles, context, and safety limitations. Human numerical examples are labeled as such so they are not mistaken for veterinary targets.
Frequently Asked Questions
Can I use the 70–180 mg/dL range for my dog or cat?
Not without veterinary direction. That interval is a commonly cited example for many nonpregnant adults with diabetes, not a universal canine or feline target. Ask the treating veterinarian to define the appropriate band and action thresholds for the individual pet.
Why does my pet’s sensor curve disagree with a blood-glucose meter?
A CGM samples interstitial fluid, while a meter measures blood, so readings can differ—especially during a rapid rise or fall. Device calibration, timing, sampling technique, and ordinary measurement uncertainty can also contribute; follow the device instructions and contact the veterinary team when the difference is clinically important.
How long should a dog or cat wear a glucose sensor?
There is no single duration that answers every veterinary question. Human guidance commonly discusses 10–14 days with at least 70% active data for routine CGM assessment, but your veterinarian may choose a different period based on the suspected problem, sensor reliability, and the pattern being investigated.
What should I do if the curve shows a very low value?
Use the individualized emergency instructions from your veterinarian rather than improvising a dose or feeding plan. If the pet is weak, confused, trembling, seizing, collapsed, or unable to eat, treat it as urgent and contact an emergency veterinary service.
