After an overnight stay

Why is my dog drinking so much after boarding?

The water bowl is often the first thing a dog visits after a stay, and the second, and the third. It looks alarming, and it usually is not. This page explains why dogs drink more after an overnight stay, how to tell catch-up thirst from too much, and the point at which a call to your vet makes sense.

The short version

Panting, play and excitement use water, and dogs make it up at home

Dogs lose water mostly by panting rather than sweating. Dr. Eileen Fatcheric, a veterinarian writing in Whole Dog Journal, explains that exercising dogs pant to regulate their temperature and lose water through evaporation, and that the hotter and drier the air, the more they lose. A stay at Dogtown means daycare playgroups by day, so an overnight guest spends days in about the most panting-heavy setting a dog has. The first evening home is when many dogs catch up.

Stress and excitement add to it. VCA's veterinary guidance notes that panting in a dog that has not exercised can be a sign of stress, and both the drive home and a big reunion can leave a dog panting on the sofa long after the last game. None of that is a problem in a dog that is bright, eating its dinner and urinating normally. It is a dog topping up after a busy few days.

How much is normal

About an ounce per pound a day is normal, and one thirsty evening is not a pattern

The same Whole Dog Journal article gives normal intake as 50 to 80 milliliters per kilogram of body weight a day, or roughly an ounce of water per pound. A 20-pound dog might drink about 20 ounces, two and a half cups; a 70-pound dog about 70 ounces, close to nine cups. Moist food supplies some of that water, so a dog on canned food drinks less from the bowl than one on dry kibble, and heat, exercise and dry air all push the figure up.

What matters is the pattern over several days rather than a single evening. The article advises seeing your veterinarian as soon as possible if a dog consistently drinks more than those amounts. If you want a number to bring to the vet, measure it: fill the bowls with a known amount, top them up from a measuring cup through the day, and add up what went in after 24 hours. Count every bowl in the house, including the one by the back door.

A new water routine

Water stations by day, your bowl at home: the routine changes, and so does the drinking

At home your dog drinks on its own schedule from a bowl it knows. During a stay, the day is organized around playgroups, with rest breaks and water stations built in, and the evening around the suite. A dog that is busy playing or watching other dogs may drink in fewer, larger sessions, then come home and settle back into its old habits. That reshuffle can look like extra thirst for a day even when the weekly total barely changes.

Overnight guests at Dogtown eat the food you pack, pre-portioned, so diet is rarely the cause; if you switched foods around the stay, that change can affect thirst too. Weather plays a part as well, and a hot Cape Ann week in July leaves every dog in a playgroup panting more. Whatever the reason, never restrict water to cut down on accidents. That decision belongs to your vet, and the article is clear that dogs should have fresh water available at all times.

When to call the vet

Call your vet when heavy drinking lasts, or arrives with other changes

Thirst that stays high is a symptom for your vet to look into rather than something to wait out. The Whole Dog Journal article names kidney disease, diabetes and Cushing's syndrome as the most common medical causes of drinking too much, and notes that excessive drinking usually comes with excessive urination. Only your vet can tell what is behind it, usually with an exam and simple tests. Bring your measurements and the report cards from the stay.

Call sooner if the drinking comes with vomiting, diarrhea, a lost appetite, low energy, accidents in a house-trained dog, a cough or a swollen belly. A large, deep-chested dog that drinks a huge amount and then retches without bringing anything up needs emergency care, because VCA lists unproductive retching and a swollen abdomen among the signs of bloat. Massachusetts Veterinary Referral Hospital in Woburn is open 24 hours, and the City of Gloucester lists local emergency veterinary offices.

  • Heavy drinking that lasts more than a day or two
  • More urination, or accidents in a house-trained dog
  • Vomiting, diarrhea, no appetite or low energy
  • Retching with nothing coming up and a swollen belly: emergency

Your dog

Puppies, seniors and dogs on medication need a closer eye on the bowl

For puppies and very active young dogs, judge against your own dog's normal rather than a chart, because growth, play and weather swing their intake from day to day. With an older dog, any lasting change in drinking is worth raising with your vet, and a stay can make an existing change easier to notice. If your senior seemed thirstier than usual before the stay, mention it now rather than putting it down to the trip.

If your dog started or changed a medicine around the stay, ask your vet whether it affects thirst. For the next stay, tell the front desk what your dog normally drinks and anything your vet has said, so the team knows what normal looks like. On pick-up day, a slow drive home and a quiet evening help a dog stop panting sooner, whether you collect in a Sunday window, 8 to 10 AM or 4 to 6 PM, or the Pup Van brings your dog home for $10 each way.

  • Seniors: raise any lasting change with your vet
  • Medication changes: ask your vet whether they affect thirst
  • Next stay: tell the front desk your dog's usual intake

Questions people ask about this

Short, complete answers you can act on today. More in the full FAQ.

How much water is too much for my dog?
As a rough guide, a veterinarian writing in Whole Dog Journal gives normal intake as about an ounce per pound of body weight a day, or 50 to 80 milliliters per kilogram. A dog that consistently drinks well beyond that over several days should see a vet. One thirsty evening after a stay, in a dog that is otherwise well, is a different thing.
Should I limit water after boarding to stop accidents?
No. Keep fresh water available and take your dog out more often instead. Restricting water is only for when your vet tells you to. If your dog is having accidents because it is drinking so much, that combination is itself a reason to call your vet, ideally with a day's measured intake to hand.
Did my dog have enough water during the stay?
Rest breaks and water stations are part of every daycare day at Dogtown, and overnight guests spend their days in those playgroups. If you want to know how your dog drank, ask the front desk what the team saw and read the stay's report cards. A big drink at home after a busy stay is common and does not by itself mean your dog went without.
Why does my dog drink more after a stay than after a daycare day?
A stay strings several playgroup days together, adds nights in a new place and ends with a big reunion, so the panting and excitement add up. Our answer on thirst after daycare covers a single day. After a stay, give your dog a quiet evening, keep water down, and call your vet if heavy drinking continues.
How long should the extra thirst last?
In a healthy dog, catch-up drinking after a stay should ease as the panting, excitement and home routine settle. If your dog is still drinking much more than usual after a day or two of normal life, measure its intake for a day and call your vet with the figure and any other changes you have noticed.
