Pocket VetDiabetes in dogs
Diabetes mellitus is a manageable hormonal disease where the body can't regulate blood sugar. With insulin and routine, diabetic dogs live full lives.
What it is
The pancreas doesn't produce enough insulin (or the body resists it), so glucose builds up in the blood instead of fuelling cells. Middle-aged, overweight, and some breeds are more prone.
Symptoms
- ●Increased thirst and urination
- ●Increased hunger with weight loss
- ●Lethargy
- ●Cloudy eyes (cataracts) over time
- ●Recurring infections
🔴 When to act now
- ●Vomiting, weakness, collapse, or sweet-smelling breath
- ●These suggest diabetic ketoacidosis — a vet emergency
Treatment & management
Most dogs need daily insulin injections, a consistent diet, and regular monitoring. With a steady routine, prognosis is good. Untreated diabetes leads to dangerous complications, so early diagnosis matters.
