AAHA’s diabetes guidance now comes as separate species-specific guidelines for dogs and cats, updated in 2026. The owner-facing explainer AAHA published on June 18, 2019 is still a useful introduction, but it is historical context rather than the current clinical guidance. This article walks through what the 2026 material and the older explainer say, where they differ, and what those points mean for a pet’s day-to-day care.
Start with the species-specific 2026 guidance
AAHA’s guidelines index lists separate diabetes management resources for dogs and cats. The index states that feline strategy differs from canine strategy, including newer SGLT2-inhibitor options for cats. A recommendation written for dogs should not be assumed to apply to cats, and the reverse is also true.
AAHA’s earlier combined document, the 2018 AAHA Diabetes Management Guidelines for Dogs and Cats (2022 update PDF), covers insulin, dietary modification, home monitoring, and hypoglycemia avoidance for both species. Use it as background, and check the current species-specific sections before acting on any detail in it.
Treating the signs of canine diabetes is the stated primary goal
AAHA’s 2026 canine guideline summary (August 31, 2026) states: “The primary goal of treating canine diabetes mellitus is to control clinical signs.” The same summary says clinical signs and weight should inform the assessment of control. It also notes that tight glycemic control is rarely possible when insulin is given twice daily as an intermediate-acting product.

A number on a meter or curve does not settle whether a dog is well controlled.
Each plan is built around the individual pet
The 2019 owner explainer states that diabetes plans depend on the individual pet. Insulin type and schedule, diet, monitoring frequency, and follow-up intervals are set for that animal, with the veterinary team adjusting them over time. Any figure in a guideline is a framework for the veterinarian’s decision, not a home instruction.
This article does not provide insulin doses, dose-change rules, or treatment advice for a specific animal. Changes to medication should only be made under veterinary direction, and a missed or unclear dose should be discussed with the veterinary team promptly.
Monitoring guides care and helps identify low blood sugar
When monitoring is warranted
AAHA’s glucose monitoring section (April 26, 2026) describes monitoring as warranted after insulin is started, after dose changes, when clinical signs recur, and when hypoglycemia is suspected. Monitoring is a tool for the care team; it does not replace the examination.

AAHA’s feline guidance, within the same glucose monitoring section, describes blood glucose curves and continuous glucose monitoring, alongside clinical signs, weight, and fructosamine. Each tool answers a different question, so a single reading is rarely enough on its own.
Use veterinary-calibrated devices
AAHA states that veterinary-calibrated glucometers are preferable to human-calibrated meters for veterinary patients. If home monitoring is part of a pet’s plan, ask the veterinary team which device to use and how to interpret its readings. A reading taken at home should be discussed with the veterinarian rather than acted on alone.
Low blood sugar and untreated diabetes are two different dangers
The 2019 explainer lists hypoglycemia as a serious risk and presents avoiding it as part of the goal of care. It also states that untreated diabetes is life-threatening. Overtreatment and undertreatment are both concerns, which is why monitoring and follow-up matter in both directions.
If an animal on insulin seems unusually weak, confused, shaky, or unresponsive, contact a veterinarian or an emergency clinic immediately rather than waiting to see whether it passes.
Diet and body condition are part of the plan
Both the 2019 explainer and the 2018 PDF treat diet and body condition as central to diabetes care. Weight is also one of the clinical markers that AAHA’s 2026 canine summary asks clinicians to consider. Diet changes should be made with the veterinary team, especially for an animal on insulin, because food timing and content affect glucose.
Home care works best with the veterinary team
The 2019 explainer emphasizes that owners carry much of the daily responsibility, including giving medication, keeping records, and watching for changes, and that this work should be coordinated closely with the veterinary team. Regular recheck visits are how the team confirms that the plan still fits the animal.
Cats: who is affected and what remission means
AAHA’s feline recognition section (April 26, 2026) reports that, in a study it cites, 82% of diabetic cats were older than 7 years, and 50% were between 10 and 15 years old. These figures are AAHA’s attribution of a cited study and describe that population only. They should not be read as a profile of every diabetic cat.
The 2019 explainer calls feline remission a reasonable goal and states that remission can occur in cats. That is the older explainer’s framing. Remission is possible but is not a guaranteed outcome, and whether it is realistic for a particular cat depends on that cat’s course and the veterinary team’s assessment.
Dogs and cats compared on the points the sources cover
| Topic | Dogs | Cats |
|---|---|---|
| Remission | Seldom occurs, per the 2019 explainer’s framing | Can occur; a reasonable goal per the 2019 explainer’s framing |
| Newer SGLT2-inhibitor options | Not stated in the sources reviewed | Noted in AAHA’s guidelines index (2026) |
| Monitoring tools named | Clinical signs and weight (AAHA 2026 canine summary) | Blood glucose curves, continuous glucose monitoring, fructosamine, clinical signs, and weight (AAHA glucose monitoring section, April 26, 2026) |
| Glycemic control note | Tight control rarely possible with twice-daily intermediate-acting insulin (AAHA 2026 canine summary) | Not stated in the sources reviewed |
| Age profile of diabetic patients | Not stated in the sources reviewed | 82% older than 7 years; 50% aged 10 to 15 years (AAHA feline recognition section, April 26, 2026, citing a study) |
Because the species-specific guidance differs, use this table to see which questions to ask the veterinary team, not as a substitute for the full guideline sections.
