AAHA releases updated diabetes guidelines for dogs

The American Animal Hospital Association released its 2026 Diabetes Management Guidelines for Dogs on Sept. 1, giving veterinary teams updated instructions for diagnosing, treating and monitoring canine diabetes. The update reflects newer tools such as continuous glucose monitors and long-acting insulins, and splits canine and feline guidance into separate documents for the first time.

Why it matters: - AAHA’s update gives veterinary teams a current playbook for a chronic disease that requires lifelong management in dogs. - The guidelines reflect newer monitoring and insulin options that can improve day-to-day care and help more dogs stay stable at home. - Better client communication is a major part of the update because diabetes care depends on long-term follow-through.

What happened: - The American Animal Hospital Association announced the 2026 AAHA Diabetes Management Guidelines for Dogs on Sept. 1. - The guidance provides step-by-step direction for diagnosing, treating and monitoring diabetes mellitus in canine patients. - AAHA said the 2026 release separates canine and feline diabetes guidance into different documents for the first time. - Jessica Vogelsang, AAHA chief medical officer, said the split reflects the unique disease process in each species.

The details: - Dogs develop diabetes mellitus through absolute insulin deficiency caused by permanent beta cell loss. - All diabetic dogs need insulin therapy. - Most dogs tolerate lifelong treatment well, and prognosis is good with appropriate therapy and monitoring. - The guidelines highlight growing use of affordable continuous glucose monitors. - The update also covers long-acting, peakless insulin formulations such as insulin degludec and glargine U-300. - Those insulin options may allow once-daily dosing. - The guidance covers diabetes pathophysiology in dogs and species-specific disease features. - It includes instructions for diagnosis, insulin treatment and monitoring. - The document also offers troubleshooting tips for common problems. - The guidelines address diabetic ketoacidosis treatment. - They recommend tests for monitoring glycemic status. - They include dietary management guidance. - They also give veterinary teams language for talking with clients about diabetes care. - Charts and algorithms cover insulin types and starting dosages, treatment adjustment, hypoglycemia troubleshooting and dogs on high insulin doses who become unregulated. - The guidelines say diabetic dogs can enjoy a good quality of life with few or no clinical signs when monitoring, diet and schedules are managed carefully. - Establishing an initial treatment plan may require more frequent follow-up visits and adjustments.

Between the lines: - Audrey K. Cook, a member of the AAHA Diabetes Management Guidelines task force, said the care of diabetic dogs has changed dramatically in recent years because of inexpensive continuous glucose monitors and a better understanding of long-acting insulins. - The update signals a shift toward more precise, more practical diabetes management in everyday veterinary practice. - The emphasis on candid conversations suggests AAHA sees owner expectations and adherence as central to outcomes, not just drug selection.

What's next: - Veterinary teams can now use the new guidance as a reference for current canine diabetes care. - The 2026 AAHA Diabetes Management Guidelines for Dogs are available at the AAHA diabetes management page. - AAHA said the guidelines are supported by Adapet Medical, Boehringer Ingelheim, Dechra and Merck Animal Health.

The bottom line: - AAHA is pushing canine diabetes care toward more tailored monitoring, more flexible insulin use and closer client-veterinary coordination.
