Question
What is diabetes insipidus and how is it different?
Sunny, owner notes“I wish my dog lived as long as I do.”Updated
I'm an owner, not a vet. This is not veterinary advice, so check anything medical with your own vet.
Short answer
Despite the name, diabetes insipidus is a problem with how the body handles water, not blood sugar. It can make a dog very thirsty and pass lots of watery urine, though plenty of other illnesses do that too. Your vet needs tests to find the cause. Never limit his water or try another dog's medicine to see if it helps.
What to know at home
Because both are called diabetes, instructions can get confusing. Ask which one has been confirmed and which tests are still to come. Never try a water-deprivation test at home.
What to write down
- Changes in drinking and urination
- All medicines and previous test results
- Whether your dog seems weak, unwell or unable to keep water down
What to ask next
Ask the vet to write down the full name of the condition and explain how it's treated. Make sure everyone who looks after your dog knows which one he has, so nobody gives the wrong medicine by mistake.

Does this mean my dog has diabetes?
Drinking more, peeing more and losing weight mean it's time to see a vet. Only the vet can tell you if it's diabetes.
