Diabetes Awareness Month: Understanding Diabetes in Dogs & Horses!

November is Diabetes Awareness Month—a time dedicated to raising awareness about a condition that affects millions of people and countless animals. Diabetes isn’t just a human disease; our dogs and horses can also develop diabetes or diabetes-like metabolic disorders that require long-term care, lifestyle adjustments, and consistent monitoring.

The purpose of this month is simple:

  • Increase awareness!
  • Encourage early diagnosis!
  • Promote better long-term outcomes!

With proper education and early intervention, animals with diabetes or insulin-related disorders can live long, active, and fulfilling lives.

Diabetes in Dogs: A Closer Look

Diabetes can affect dogs of any breed, age, or gender, although it is most commonly diagnosed in middle-aged to senior pets. Early recognition and consistent management greatly improve a dog’s prognosis. Understanding the types of diabetes, common symptoms, and treatment options empowers owners to help their dogs stay healthy and comfortable.

Types of Diabetes in Dogs

• Type 1 Diabetes (Insulin-Dependent Diabetes Mellitus – IDDM)
This is the most common form in dogs. The pancreas cannot produce enough insulin, which is needed to move glucose from the bloodstream into the cells for energy. Because insulin-producing cells are damaged or destroyed, dogs with Type 1 diabetes require lifelong insulin injections—usually once or twice daily. Diet structure and routine are also essential for maintaining stable blood sugar.

• Type 2–Like Diabetes
True Type 2 diabetes is rare in dogs, but some dogs develop a similar condition caused by obesity, inflammation, or hormonal imbalances that reduce insulin sensitivity. Even in these cases, dogs often progress to needing insulin injections. Weight management and treatment of underlying conditions can greatly improve outcomes.

Higher-Risk Dogs Include:

  • Intact females
  • Obese pets
  • Breeds such as Miniature Schnauzers, Poodles, Dachshunds, Beagles, and Cairn Terriers
  • Dogs with a history of pancreatitis
  • Senior dogs (7+ years)

Early Warning Signs in Dogs

Diabetes often develops gradually. Watch for:

  • Increased thirst
  • Increased urination
  • Weight loss despite normal or increased appetite
  • Cloudy or bluish eyes (cataracts)
  • Reduced energy or increased fatigue
  • Vomiting or dehydration (advanced cases)

If you notice these signs, a veterinary exam and bloodwork are the next essential step.

Diagnosis

Diagnosis may include:

  • Blood glucose testing
  • Urinalysis (checking for glucose or ketones)
  • Fructosamine levels (long-term glucose control)
  • Additional bloodwork to rule out infections, pancreatitis, Cushing’s disease, or organ dysfunction

Most testing can be completed during a routine vet visit.

Treatment and Management

A diabetic dog can live a full, healthy life with:

  • Daily insulin injections on a consistent schedule
  • A controlled diet, often high-fiber or prescription diabetic food
  • Regular, moderate exercise
  • Routine monitoring, including at-home checks or in-clinic glucose curves
  • Management of complications such as cataracts, UTIs, or pancreatitis

Once stabilized, many diabetic dogs return to their normal personalities and routines.

 

Diabetes & Metabolic Disorders in Horses

True diabetes is rare in horses, but insulin dysregulation—a condition closely related to diabetes—is extremely common. When the body struggles to regulate blood sugar, insulin levels become persistently high, increasing the risk of serious complications such as laminitis.

Two primary endocrine conditions cause most cases of insulin dysregulation:

  • Equine Metabolic Syndrome (EMS)
  • Pituitary Pars Intermedia Dysfunction (PPID or Cushing’s Disease)

Both disorders affect how the body processes insulin and significantly increase laminitis risk.

Equine Metabolic Syndrome (EMS)

EMS is especially common in “easy keeper” breeds such as ponies, Morgans, Arabians, Mustangs, and Paso Finos, though any horse can develop it.

Key features include:

  • Insulin resistance: cells respond poorly to insulin
  • Regional or general obesity: fat along the crest, rump, or around the sheath/mammary area
  • High risk of laminitis: elevated insulin is strongly linked to painful hoof disease

Most EMS horses improve significantly with controlled diets, strategic weight management, and consistent exercise.

PPID (Cushing’s Disease)

PPID is common in older horses. An overactive pituitary gland produces excess hormones that disturb normal insulin function.

Common signs include:

  • A long, shaggy coat that fails to shed
  • Muscle wasting along the topline
  • Increased drinking and urination
  • Slow wound healing or recurrent infections
  • Increased risk of laminitis

Many horses with PPID also have EMS, making combined management essential for preventing laminitis.

Why Insulin Issues Matter: The Laminitis Connection

Laminitis is one of the most painful and dangerous hoof conditions. High insulin levels—whether due to EMS, PPID, or dietary triggers—can damage the delicate structures within the hoof, leading to inflammation, rotation, or sinking of the coffin bone.

Early detection of metabolic problems is key to preventing severe episodes.

Signs of Insulin Dysregulation in Horses

Watch for:

  • Cresty neck or localized fat pads
  • History of laminitis or hoof sensitivity
  • Excessive thirst or urination
  • Lethargy or decreased performance
  • Delayed shedding (especially with PPID)
  • Muscle loss

These signs often develop gradually and may be mistaken for aging or normal weight gain.

Diagnosing Metabolic Disorders in Horses

Veterinarians may recommend:

  • Basal insulin and glucose testing
  • Oral sugar tests (OST)
  • TRH stimulation testing for PPID
  • ACTH blood testing

Because early metabolic changes often appear before obvious symptoms, screening is extremely valuable.

Managing Horses with EMS or PPID

  • Diet & Nutrition:
    • Low-sugar, low-starch forage
    • Restricted or no grain
    • Controlled pasture turnout
    • Soaked hay when needed
  • Weight Control: Gradual, steady weight loss is essential for overweight horses.
  • Medication: Most PPID horses benefit from pergolide, a daily medication.
  • Hoof Care: Close collaboration with a farrier and immediate attention to hoof soreness are critical.
  • Exercise: Regular movement improves insulin sensitivity (when the horse is not laminitic).

 

Why Early Detection Matters

Early diagnosis can prevent:

  • Painful or life-threatening complications
  • Organ damage
  • Laminitis in horses
  • Cataracts and neuropathy in dogs
  • Diabetic crises
  • Higher long-term veterinary costs

Monitoring your animal’s weight, appetite, water intake, and behavior provides important early clues to their health.

What Pet & Horse Owners Can Do This Month

Schedule a wellness exam
Review your animals diet
Watch for early signs
Share awareness with other owners
Ask your veterinarian about screening—especially for overweight or senior animals

A Final Message for Diabetes Awareness Month

Diabetes and metabolic disorders may feel overwhelming at first, but with early recognition and proper management, most animals can thrive. Awareness is the first step—this month is a great opportunity to start meaningful conversations with your veterinarian, barn manager, or fellow pet owners.
