Why is my dog so tired after boarding? What’s normal, and when to call the vet

Think of the last time you came home from a conference or a wedding weekend. You weren’t sick, just running on adrenaline for days, and your body wanted to catch up. A kennel stay is the dog version of that.

• More activity, less deep rest. Boarding means play groups, walks, new people and a constant soundtrack of other dogs barking. A Texas A&M veterinarian points out that boarding facilities are often loud, especially for dogs.
• A body that stayed switched on. In a 2014 study of 29 pet dogs, researchers measured stress-related hormone markers in each dog’s urine at home and in a boarding kennel. Both markers were higher in the kennel, and the dogs were generally more active there.
• Unfamiliar sleep. New bedding, new smells and dogs on either side make it hard to sink into the long, uninterrupted sleep they get on your sofa.
• Relief. Home is quiet, safe and familiar. Many dogs simply crash once they get there.

That study comes with an honest twist. The researchers found no definitive evidence that the dogs were negatively stressed by kenneling. The hormone changes showed arousal, which can mean excitement as easily as worry. A tired dog after boarding may have had a great time, a tough time, or a bit of both. Either way, the body needs to come down.

Texas A&M’s veterinary college says some readjustment is normal: pets may want extra attention, sleep more, or take a day to settle back into their routine. Here is what usually falls in the normal range, and for how long.

Some dogs swing the other way and come home wired, zooming around the house before collapsing. That is normal too, as long as they settle within a day.

Length of stay and your dog’s age matter. A puppy or a senior can take longer to bounce back than a young adult, and a two-week stay usually means a longer catch-up than a weekend. What you are looking for is a trend: each day a little more like your dog’s normal self. A dog that is getting worse rather than better needs a vet, whatever the reason.

Stress is one of the most common reasons. VCA lists stress following travel, boarding or other changes in the environment as a common cause of diarrhea. You may see softer or more frequent stools for a day or two.

A food change can add to it, which is one reason to send your dog’s own food (see what to pack for dog boarding).

VCA’s threshold is clear: if frequent liquid or semi-liquid stools last more than two days, call your vet. Keep fresh water available, because dehydration can develop quickly, and don’t give probiotics or over-the-counter remedies without checking with your vet first.

Kennel cough is a group of contagious respiratory infections that spread wherever dogs share air, and boarding is a classic place to catch it even with up-to-date vaccines. Dogs are contagious before they show signs, so a cough can start several days after you bring your dog home rather than on the drive back.

• A dry, honking cough, sometimes ending in a gag that looks like your dog is trying to bring something up
• Sneezing, or a runny nose or eyes
• Coughing that gets worse with excitement, exercise or pulling on the leash

VCA says most cases resolve within 7 to 10 days with supportive care. Keep a coughing dog away from other dogs, use a harness instead of a collar, and let the kennel know, since they will want to watch the rest of their guests. Our guide to dog boarding vaccine requirements explains why vaccinated dogs can still catch it.

Behavior changes are usually short-lived and come from a change in routine, not a bad experience. Common ones:

• Velcro dog. Following you from room to room for a few days is very common and fades as the routine returns.
• Ignoring you at first. Some dogs are briefly aloof, then fine by the evening. It doesn’t mean they’re upset with you.
• House-training slips. A dog used to a kennel run may have an accident or two. Go back to frequent trips outside for a few days.
• Mouthy or rough play. A dog fresh from group play may try the same games on you or the cat. Calmly redirect.

Signs that are worth a closer look: new fear of other dogs, flinching when touched in a particular spot, limping, or new cuts or scrapes. The AKC suggests checking at pickup for distress signs such as heavy panting, drooling or a stiff body, and for any new bruises, cuts or scratches. Ask the kennel about anything you find. A good facility will already have noted it.

1. Let your dog sleep. Skip the dog park and big outings for a day or two.
2. Offer water in reasonable amounts rather than a huge bowl to gulp all at once if your dog seems frantic to drink.
3. Return to normal meal times with the usual food, and keep portions normal.
4. Get back into your regular walk and bedtime routine as soon as possible.
5. Keep an eye on stool, appetite, energy and any cough for the next week, and call your vet if anything on the warning list shows up.

If your dog comes home exhausted, scared or unwell after every stay, it’s worth trying a different setup next time: a quieter kennel, a private run without group play, or an in-home sitter. You can compare options in the dog boarding directory.
