Canine diabetes (diabetes) — identify symptoms and start treatment

📞 Internal medicine doctors in Vantaa: 010 739 9130

Canine diabetes (diabetes mellitus) is a generalizing disease similar to type 1 diabetes in humans. A dog's pancreas stops producing insulin, causing blood sugar to rise dangerously high.

If left untreated, diabetes is life-threatening, but with the right treatment, a diabetic dog can live a normal, joyful life for years.

Main symptom: Drinking and peeing

The classic symptom of diabetes is PU/PD (polyuria/polydipsia), that is, increased urination and drinking.

  • The dog drinks the cup of water empty in an instant and asks for more.
  • A dog that has been indoor clean begins to pee inside or is unable to hold back for the duration of the working day.
  • Urine is pale and comes out in large quantities.

Other symptoms:

  • Weight loss: The dog will lose weight even if it eats well (or even greedily). The body cannot make good use of food without insulin.
  • Cataracts: The dog quickly goes blind when the lenses become cloudy under the influence of sugar.

How is diabetes treated?

Canine diabetes requires commitment from the owner, as the treatment is lifelong. At the animal hospital Sacrum, we teach the owner to do everything necessary at home.

1. Insulin injections

The dog is given insulin by injection under the skin once or twice a day, when feeding. Most dogs don't even notice a tiny needle.

2. Diet

A steady blood sugar level requires a regular feeding rhythm and high-quality, fiber-rich food.

3. Exercise

Regular exercise helps keep your sugar balance in check.

Do you suspect diabetes?

Bring the dog to the examinations Veterinary Hospital in Sacrum. The diagnosis is easily confirmed by a blood test and urine sample. The earlier the treatment is started, the better the dog's body (and eyesight) will be spared from damage.
