Change in Diet

Have you changed your dog’s diet by switching to dry kibble? Pay attention to what you have been feeding your pet lately. Feeding your dog sodium rich foods may cause them to drink more water. Feeding your dog excessive dog treats may also be a reason for excessive thirst.

Aging

Is your dog a senior friend? Aging might be a common culprit for excessive thirst especially if your dog breed is prone to kidney and liver diseases. Infection and canine trauma can also trigger diseases related to the liver and kidneys.

Lactating Dogs

Medication

How to Treat it

In order to treat excessive thirst, it is imperative you notice the amount water being consumed by your pet.

Once you have ruled out all these causes, it is imperative you plan a visit to the vet.
