Why Is Your Dog Thirsty? continued...

Medication

Just as with people, some drugs can lead to excessive thirst in your dog, including:

  • Anti-inflammatory drugs like prednisone, which may be used to treat many conditions in dogs, including asthma, allergies, and inflammatory bowel disease.
  • Heart failure drugs, such as furosemide, lead to increased urine production and a compensatory increase in thirst.
  • Seizure medications like phenobarbital may have side effects that include excessive thirst and urination, as well as excessive appetite.

Diet

A dry food diet -- which may be as little as 5%-10% water -- can also lead to noticeable thirst in your dog. High sodium foods will also cause your dog to drink more.

Large amounts of salt can be poisonous to your pet, so avoid sharing highly salty "people" food with your dog. Signs your dog may have eaten too many sodium-rich treats include tremors, diarrhea, depression, and vomiting.

 

 

Keeping an Eye on Water Consumption

It's easier to notice changes in your dog's thirst or drinking behavior if you develop a water bowl routine.

  • Refill your dog's bowl at roughly the same time daily.
  • Fill the bowl to about the same level each time.
  • Pay attention to how much you put in each day and how much is left.

Water is critical to your dog's health and well-being. Never deprive your dog of water. If you're worried your dog is drinking too much (or not enough), don't wait, give your vet a call.
