Diabetes in dogs and cats: diagnosis and management

Dogs and cats should not be managed using the same protocol. Diagnosis, treatment and nutrition depend on the species and the individual animal’s condition.

Signs and diagnosis

Increased thirst and urination, appetite changes and weight loss require assessment. Diagnosis combines the clinical picture with test results rather than applying isolated thresholds to every animal.

In cats, stress can also affect some results and must be taken into account.

Different management for dogs and cats

The veterinarian selects the appropriate strategy, explains monitoring and assesses nutrition and concurrent diseases. Options available for some cats require specific selection criteria and checks.

Do not change the medicine, diet or method of administration without veterinary advice.

Emergencies and monitoring

Sudden weakness, altered mental state, persistent vomiting or refusal to eat may indicate a complication and require prompt assistance. A clinical diary helps the veterinarian interpret the course of the condition.
