Many dog owners notice their dogs sucking on blankets and wonder why this odd behavior happens. It can look cute, but sometimes it feels strange or even worrying. Dogs often have habits we don’t fully understand, and blanket sucking is one of those quirks.
If you’re searching for answers, you’re not alone. This behavior can mean different things depending on your dog’s age, breed, history, and environment. Let’s dive into the main reasons dogs suck on blankets, what it could mean for their health, and how you can help your furry friend.
What Is Blanket Sucking?
Blanket sucking is when a dog puts a blanket (or sometimes other soft objects) in its mouth and gently sucks, nibbles, or chews on it for a few minutes or even longer. Some dogs do this only when they’re relaxed, while others suck on blankets whenever they feel anxious, bored, or sleepy.
It’s not the same as aggressive chewing, which can destroy the blanket. Blanket sucking is usually gentle and repetitive.
Why Dogs Suck On Blankets: Common Causes
Dogs might suck on blankets for several reasons. Here are the most common explanations:
1. Comfort And Security
Many dogs see their blanket as a comfort object. Just like children hold onto teddy bears, dogs may use blankets to feel safe. This is especially true if your dog started sucking as a puppy. Puppies often suckle for comfort, and the feeling of a soft blanket reminds them of their mother and littermates.
2. Early Weaning
Some experts believe that dogs who were weaned too early (taken from their mother before 8 weeks) are more likely to suck on blankets. Early weaning can leave puppies searching for something to replace the comfort of their mother’s milk and warmth. This behavior can continue into adulthood.
3. Breed Tendencies
Certain breeds are more likely to suck on blankets. For example, Doberman Pinschers, Dachshunds, and Siamese cats are often reported to do this. Studies show that about 30% of Dobermans develop blanket sucking or similar behaviors. Genetics play a role, so if your dog’s breed is known for this habit, it may be a normal trait.
4. Stress And Anxiety
Dogs sometimes suck on blankets when they feel anxious or stressed. This is a self-soothing behavior, similar to nail-biting in humans. Changes in the environment, loud noises, new family members, or being left alone can trigger stress. Sucking on blankets helps many dogs calm themselves.
5. Boredom
If your dog doesn’t get enough mental or physical stimulation, it can become bored. Blanket sucking is one way dogs entertain themselves. This is more common in dogs left alone for long periods, or those without enough toys or activities.
6. Medical Issues
In rare cases, blanket sucking may be linked to medical problems. Dogs with gastrointestinal issues, nutritional deficiencies, or certain neurological conditions might suck on blankets to relieve discomfort. If your dog’s sucking is sudden, intense, or paired with other symptoms, a vet visit is important.
7. Habit Formation
Sometimes, dogs simply develop a habit. If a puppy starts sucking on blankets and is never discouraged, it can become part of their routine. Habits are hard to break, especially if they make the dog feel good.

How Blanket Sucking Differs From Other Behaviors
It’s important to know how blanket sucking compares to other behaviors like chewing, licking, and biting. Here’s a quick comparison:
| Behavior | Typical Cause | Common Signs | Possible Concern |
|---|---|---|---|
| Blanket Sucking | Comfort, anxiety, early weaning | Gentle sucking, relaxed posture | Usually harmless unless obsessive |
| Chewing | Teething, boredom, stress | Destructive, strong jaw action | Can damage objects, risk of swallowing |
| Licking | Grooming, anxiety, allergies | Continuous licking, wet patches | Can lead to skin issues |
| Biting | Aggression, fear, play | Quick jaw snaps, growling | Possible injury, behavioral problem |
When Should You Be Concerned?
Most blanket sucking is harmless. However, there are times you should watch closely:
- Your dog is obsessive (cannot stop sucking)
- The behavior started suddenly
- There are signs of distress, illness, or pain
- Your dog is ingesting fabric (risk of blockage)
- Blankets are being destroyed
- Other strange behaviors appear at the same time
If you notice any of these signs, it’s wise to consult your vet.

Is Blanket Sucking Linked To Health Problems?
While blanket sucking itself is usually safe, it can sometimes connect to health problems. Here are some risks:
Gastrointestinal Blockage
If your dog bites off and swallows pieces of fabric, it can cause a blockage in the stomach or intestines. This is a serious medical emergency. Symptoms include vomiting, loss of appetite, and lethargy.
Dental Issues
Constant sucking can wear down teeth or lead to gum irritation. If your dog seems uncomfortable or avoids eating, check their mouth and see your vet.
Allergies
Some blankets have fibers, dyes, or detergents that may cause allergic reactions. Watch for itching, redness, or rash around the mouth.
How To Reduce Blanket Sucking
If you want to reduce this behavior, try these practical steps:
- Provide plenty of mental and physical stimulation. Exercise, training, and toys help keep your dog busy.
- Give your dog safe chew toys and rotate them regularly.
- Use calming aids like pheromone diffusers or anxiety wraps if your dog is stressed.
- Keep blankets clean and free from harsh detergents.
- If the behavior is obsessive, limit access to blankets and redirect to other activities.
- Train your dog with positive reinforcement. Reward them when they choose toys or stop sucking.
- If you suspect a medical issue, visit your vet for advice.
Which Breeds Are Most Likely To Suck On Blankets?
Breed plays a big role. Here’s a comparison of some breeds and their tendency for blanket sucking:
| Breed | Likelihood | Notes |
|---|---|---|
| Doberman Pinscher | High | Often linked to early weaning |
| Dachshund | Medium | Common in puppies |
| Labrador Retriever | Low | Rare unless stressed |
| Shih Tzu | Medium | May do this for comfort |
| Mixed Breeds | Variable | Depends on history |
Should You Stop Your Dog From Sucking On Blankets?
Most experts agree that if your dog’s blanket sucking is gentle, not obsessive, and doesn’t cause harm, you don’t need to stop it. It can be a healthy, comforting habit. However, if your dog chews or ingests fabric, or if you see signs of anxiety or health issues, intervention is important.
Some non-obvious insights:
- Dogs who suck on blankets may be more sensitive to changes in routine. If you move homes or add a new family member, this behavior can increase.
- Blanket sucking can sometimes signal hidden health problems. For example, some dogs with low thyroid levels develop repetitive behaviors. If your dog’s behavior changes, ask your vet about a full health check.

Practical Tips For Owners
Here are some helpful tips for managing blanket sucking:
- Make sure your dog’s blanket is safe. Avoid blankets with loose threads or buttons.
- Wash blankets with gentle, dog-safe detergents.
- Supervise your dog during sucking sessions, especially if they are young or new to the behavior.
- Try offering a special “sucking blanket” that is only available at certain times, such as bedtime.
- If your dog seems anxious, create a calm environment with soft music, routine, and gentle attention.
The Science Behind Blanket Sucking
Blanket sucking is a form of oral fixation. In animals, oral behaviors are sometimes linked to how they were raised. Puppies suckle for weeks, and if they are separated too early, they may keep searching for comfort through their mouth. Research in animal behavior shows that dogs develop habits based on early experiences, genetics, and environment.
A study published in the Journal of Veterinary Behavior found that about 12% of dogs show oral behaviors like blanket sucking, and most cases are harmless. However, dogs with stressful backgrounds show higher rates, about 25%. This suggests that stress and upbringing both play a role.
When To Seek Professional Help
If your dog’s blanket sucking is causing harm or distress, or if you see sudden changes in behavior, it’s important to get help. A veterinarian can rule out medical issues and advise on training or anxiety management. Animal behaviorists can offer strategies for breaking obsessive habits.
