Why Your Dog Is Always Thirsty

Dogs are messy, hit-and-miss drinkers, so it can sometimes be hard to know just how much water they get in a day.

Most need about an ounce of fluids per pound of body weight per day, so a 10-pound dog needs a bit over a cup of clean water daily. Really active or lactating dogs may need more and puppies generally drink more than adult dogs. If your dog drinks a lot more than that, it may signal a health problem. Read on to learn more.

Lower Urinary Tract Problems and Infections in Dogs

There are many problems that can affect a dog’s lower urinary system. Incontinence, bladder stones or crystals in the urine, bacterial infections, cancer, trauma or even obstruction of the urethra, the tube that allows urine to pass from the bladder to the outside of the body, can occur.

Why Is Your Dog Thirsty?

Many things can affect how much your dog drinks, from weather to activity level to diet.

Common sense should be your guide when it comes to your dog's thirst. If your canine companion is drinking so excessively you're noticing the change, it's probably time to talk to your vet who, with a few tests, can get at the root cause of your dog's increased thirst.

In the meantime, a few reasons why your dog might be unusually thirsty include:

Dehydration

Hot summer days, play, exercise, illness, infection -- all of these can lead to dehydration in dogs and trigger them to seek water. Along with increased thirst, signs that your pet may be dehydrated include: lethargy; dry gums and tongue; and thick rope-like saliva.

Dehydration can turn life threatening fast, so if you suspect your dog is very dehydrated, seek veterinary care right away. If your dog seems mildly dehydrated but is not vomiting, give your pet small amounts of water -- one teaspoon for a little dog, 1-2 tablespoons for larger dogs -- every ten minutes for a few hours.

Don't let your dog have free access to a lot of liquids when he is dehydrated, as drinking too much too fast could cause vomiting.

Illness

Many conditions can lead to excessive thirst or dehydration in your dog, including liver disease, diabetes, Cushing's disease, cancer, diarrhea, fever, infection, and kidney disease.

Sometimes, however, it may not be the condition itself causing your dog's excessive thirst, but the medication used to treat it. Talk to a vet about your dog's medication and its side effects; if drugs are behind your dog's thirst, the vet may be able to lower the dosage.
