Canine Diabetes Mellitus Welfare and Insulin Management

Diabetes mellitus in dogs requires lifelong insulin therapy, but well-managed dogs achieve excellent quality of life with appropriate owner commitment.

Key Facts

Diabetes mellitus affects approximately 1 in 300 dogs in the UK
Middle-aged to older intact female dogs and Samoyeds are at highest risk
Twice-daily insulin injections with consistent feeding times are the cornerstone of management
Unregulated diabetes causes blindness from cataracts in over 75% of affected dogs
Home glucose monitoring using continuous glucose monitors is increasingly accessible

Welfare Considerations

Uncontrolled diabetes causes progressive welfare compromise through weight loss, excessive thirst, cataracts, and susceptibility to infections. With appropriate management, diabetes does not need to significantly impair quality of life. Owner commitment to twice-daily injections, consistent feeding times, and regular veterinary monitoring is essential. Cataract surgery restores vision in dogs blinded before diagnosis, dramatically improving their welfare. The main welfare risk is inadequately monitored diabetes in owners unable to commit to the management demands.

What You Can Do

Commit to twice-daily insulin injections and consistent feeding schedules if your dog is diagnosed
Monitor for signs of hypoglycaemia including weakness and disorientation during dose adjustment
Discuss cataract surgery with your vet if your dog loses vision following late diabetes diagnosis
Ask your vet about continuous glucose monitoring options to improve management precision
