Dog Diabetes Mellitus: Insulin Management at Home

Diabetes mellitus in dogs requires daily insulin injections and dietary management. With good owner training, most diabetic dogs achieve excellent quality of life.

Key Facts

Canine diabetes mellitus predominantly affects middle-aged to older dogs
Neutered female dogs and certain breeds including Samoyeds are at elevated risk
Daily insulin injections are required in almost all canine diabetic patients
Consistency in feeding time, food type and exercise level is critical for regulation
Diabetic cataracts develop rapidly in most unregulated dogs within months

Welfare Considerations

Uncontrolled diabetes causes persistent thirst, urination, weight loss and lethargy that significantly impair quality of life. The daily injection routine, while appearing burdensome to owners, causes minimal discomfort with appropriate needle gauge and technique. Hypoglycaemia from insulin overdose represents the most acute welfare emergency — signs of weakness, trembling and collapse require immediate glucose supplementation. Regular glucose curve monitoring helps maintain regulation and prevents both hypo- and hyperglycaemia.

What You Can Do

Attend a diabetic management training session with your vet or veterinary nurse
Feed the same food in the same amount at the same time each day
Monitor water intake and urine output daily as indicators of regulation
Keep glucose syrup or honey accessible for hypoglycaemia emergencies
Attend 6-12 weekly glucose curves until stable, then every 3-6 months
