So how can you tell if your Great Dane is abnormally thirsty?

The best way to evaluate your Great Dane’s thirst level is to monitor their drinking and urination frequency compared to their normal rate.

You can do this by providing them with a certain quantity of water in their drinking bowl and monitoring how often you refill the water in a day.

Temporary thirst is normal and common for a Great Dane but prolonged thirst is a sign of an underlying medical condition.

Complications

Thirst can be caused by various illnesses which can be life-threatening to a Great Dane. For example, Pyometra is a secondary infection that affects female Great Danes that are not spayed, which if left untreated leads to fatal outcomes.

What To Do If Your Great Dane Is Always Thirsty

Temporary thirst due to warm weather, play, or exercise can be managed at home by providing enough drinking water.

If you notice that your Great Dane is always thirsty, and drinking more water than usual, take them to the veterinarian right away, because it can be an indication of a health condition.

Take a sample of the urine produced by your Great Dane to the veterinarian which will be tested.
