How to Recognize

A dog typically needs to drink one ounce of water for every pound he/she weighs. Though you should expect your dog to drink more on hot days and if he/she is extremely active, excessive thirst in your pet can be a sign of an underlying health issue.


Your pet may be excessively thirsty due to dehydration. Dehydration in pets usually occurs in high temperatures, if your pet is extremely active, and/or maintains a very dry diet. Excessive thirst can also be a symptom of diseases such as kidney failure, diabetes, cancer, or liver disease.


If your pet appears to be dehydrated, provide your pet with cool water immediately. If you are worried your pet drinks too much or too little water, seek advice from your veterinarian.
