3 Strange Things Your Dog Might Do When They’re Sick

Dogs can’t tell us when they’re feeling unwell, but they often express discomfort in ways that seem odd.


As a pet parent, recognizing these subtle signals early can make all the difference.


Here are three unusual behaviors that might mean your dog isn’t feeling their best.

1. Suddenly Sleeping in Weird Places

If your normally couch-loving dog suddenly starts curling up behind the toilet, under the bed, or in a closet, there might be more to it than just a quirky mood.


Dogs instinctively seek quiet, hidden places when they feel vulnerable or weak, just like their wild ancestors did to avoid predators. This behavior can be linked to fever and pain.


What to do: Monitor for other symptoms like lethargy, shivering, or loss of appetite, and consult your vet if it persists.

2. Licking or Chewing at “Nothing”

It’s normal for dogs to groom themselves occasionally, but obsessive licking, especially at paws, the air, or even furniture, can be a sign of underlying illness.


Nausea, allergies, or discomfort from internal pain can all trigger this behavior. In some cases, excessive licking releases endorphins that help them cope with stress or sickness.


What to do: Keep track of how often and how long the behavior lasts, and let your veterinarian know if it’s new or worsening.

3. Acting “Needy” One Minute, “Distant” the Next

Sick dogs sometimes have shifting moods. They may want constant closeness for comfort, then retreat to be alone without warning.


This push-pull behavior can indicate discomfort, fever, or internal pain. Illness can make them anxious and fatigued, leading to inconsistent social behavior.


What to do: Pay attention to patterns. If the change in temperament coincides with other symptoms, like reduced appetite, vomiting, or changes in bathroom habits, it’s time to call the vet.

Bottom line

These strange behaviors don’t automatically mean your dog is sick.


At the end of the day, you know best what is and isn’t normal for your dog. But if you notice sudden, unexplained changes in sleeping habits, grooming, or social behavior, it’s safest to get them checked out.


Early intervention can save you a lot of stress and keep your four-legged friend healthy and happy.
