You may feel alarmed when your dog whimpers during his sleep and may wonder if you should wake him up. As the popular saying goes “let sleeping dogs lie.” Dogs can be quite vocal during their sleep often whimpering, crying, barking and even howling out loud. In most cases, there’s nothing to worry about; chances are Mr. Sandman just sprinkled a touch of sleepy dust over Scruffy’s forehead.


Requesting attention

Make sure your dog is sleeping when he’s whimpering. If not, the whimpering may be his way of trying to grab your attention. For instance, if you are crate training a puppy, the whimpering may be the pup’s way of telling you he needs to be taken out to potty. Your dog may be thirsty, or too hot or cold. In some cases, he may be hoping for attention because he feels lonely or bored. Consider that whimpering before sleeping or in the middle of the night may be triggered by some sort of discomfort or pain. Consult with your veterinarian if there is a concern about the whimpering.

First off — is dog whimpering always negative?

“Dogs can whimper or whine for many reasons, and while whining can be a normal behavior for some dogs when they’re excited or want something, it can also be a sign of an underlying health issue,” says Dr. David Dilmore, DVM, of Banfield Pet Hospital.


According to Dr. Dilmore, dog whimpering communicates something — but that something isn’t always negative. A dog whimpering could indicate that she wants something, like a treat, a toy or that cheese stick you’re eating. Or a dog may whimper if he’s excited to go for a walk.

So, why do dogs whimper? It all comes down to context.

As mentioned above, dog whimpering occurs for a multitude of reasons. The key to differentiating these different causes for dog whimpering is context.

“Your dog could be whining for many reasons,” says Dr. Dilmore. “You may need to investigate and see if it’s being caused by any of these factors.”

  1. Being uncomfortable or in pain
  2. Illness
  3. Feeling anxious
  4. Needing something / excitement

In these situations, context is everything. Is your dog whimpering in conjunction with vomiting or experiencing diarrhea? Your dog might be sick. Is your dog whimpering and limping? She might be uncomfortable or in pain. Or, is your dog whimpering in the car? Sounds like he’s anxious and carsick. If your dog is whimpering while you eat at the dinner table, that might be because she “needs” — a.k.a. wants — what you’re eating, and if she whimpers when someone new walks into the house, then the whimpering might be due to excitement. It’s all about surveying the situation.

“If you notice any changes with your dog’s vocalization behavior or if you’re concerned about her health, you should take her in to see a veterinarian,” says Dr. Dilmore.

A closer look at four reasons for dog whimpering

As Dr. Dilmore mentions, dog whimpering could mean a lot of different things depending on the situation. Below, Dr. Dilmore explains four common scenarios that cause dog whimpering and what each of them means.

1. Being uncomfortable or in pain:

Sometimes an injury or another kind of underlying health issue can cause dog whimpering.

“If your dog is uncomfortable, this can be caused by things like joint issues, pain in the belly from an illness, spinal pain or an injury,” Dr. Dilmore explains. “If you feel that your pet is uncomfortable or in pain, you should contact your veterinarian and schedule an appointment as soon as possible as they can help determine the cause of the whimpering.”

2. Illness:

Sickness — such as vomiting or experiencing diarrhea — could also be the cause of that dog whimpering.

“If you notice other symptoms in your dog like not wanting to eat, vomiting, diarrhea, coughing or lethargy, she may be whining because she’s sick. If this is the case, it’s time to visit your veterinarian so they can help determine the cause of their whimpering,” Dr. Dilmore says.

3. Feeling anxious:

Anxiety isn’t just a human thing; it affects our pets, too. Some reasons that dogs might experience anxiety include traveling in the car or by airplane, thunderstorms, fireworks, a change in environment or being left alone a lot — also known as separation anxiety.

“There can be many different types of anxiety in dogs that could cause whimpering, including separation anxiety or noise phobia,” Dr. Dilmore explains. “In some cases, changes in the home environment can also cause stress-related anxiety that may manifest itself in the form of whining or whimpering, whether it’s moving to a new home, a change in your work schedule, a new child or pet sibling or hosting out-of-town-guests. In some cases, your dog may need some time to adjust, but if you have any concerns or if this behavior persists, you should schedule a visit with your veterinarian to rule out any underlying health issues,” he adds.

4. Needing something or excitement:

This is likely one of the most common causes of whimpering in dogs. Like babies, dogs will sometimes cry or whine to get attention or to acquire what they want, whether it’s a ball, toy, treat, food or water. Or just maybe, a whimpering dog might need to go out for a walk.


“Your dog may start whining if he’s looking for you to give him something, from attention and a belly rub to play time or food,” Dr. Dilmore says. “Some dogs will also whine or whimper when they are excited. This can happen when they see you pick up their leash or someone new comes to visit. While whining can be a normal behavior for some dogs, it can also potentially be a sign of an underlying health issue. If you notice any changes with your dog’s vocalization behavior, or if you’re concerned about her health, you should take her in to see a veterinarian.”

When is a dog whimpering a cause for concern?

As you can see, sometimes, dog whimpering is just a way for our furry friends to communicate with us or with one another. But in other cases, dog whimpering is a cause for concern and requires a vet visit.

Dr. Dilmore concludes, “If you think your dog might be whining because he’s uncomfortable, sick or anxious, you should contact your veterinarian.”
