Why Dogs Chew Blankets: 6 Reasons And How To Stop

Finding your dog happily chewing, sucking, or nibbling on a blanket can be equal parts cute and confusing. While it often looks harmless, persistent blanket chewing can sometimes signal deeper emotional or medical issues that are worth your attention.

This guide explains the most common reasons dogs chew on blankets, when it becomes a problem, and practical, humane strategies you can use to manage and redirect the behavior.

Is Blanket Chewing Normal for Dogs?

Chewing is a completely normal behavior for dogs of all ages. Healthy dogs use their mouths to explore, play, comfort themselves, and relieve stress. Many puppies and even some adults will mouth or gently chew on soft items like blankets without causing any damage.

The key is to distinguish between normal comfort chewing and chewing that is excessive, destructive, or obsessive. According to veterinary behavior experts, normal chewing:

• Is intermittent rather than constant
• Does not lead to swallowing large pieces of fabric
• Does not cause injury to teeth or gums
• Is easy to interrupt or redirect with a toy or cue

By contrast, destructive chewing is a widely recognized behavior problem that may be driven by anxiety, frustration, or lack of appropriate outlets for normal canine behavior.

Main Reasons Dogs Chew or Suck on Blankets

Several overlapping emotional, developmental, and medical causes can contribute to blanket chewing. Often more than one factor is at play.

1. Early Weaning and “Comfort Sucking”

Dogs that were weaned too early from their mother are more likely to develop a blanket-sucking or blanket-chewing habit. This behavior, sometimes called comfort sucking, mimics nursing and can become a self-soothing ritual that persists into adulthood.

• Usually starts in puppyhood
• Often involves gentle nibbling or sucking rather than tearing
• Frequently appears at bedtime or during quiet rest

For many dogs, this is emotionally meaningful but medically harmless, as long as they are not ingesting fabric or becoming distressed if the blanket is unavailable.

2. Puppy Teething and Oral Discomfort

Puppies normally go through a teething phase from roughly 3 to 6 months of age. During this time, chewing on soft or slightly resistant items like blankets can help relieve gum discomfort.

• Chewing increases when teeth are erupting or loosening
• Puppies may target any soft fabric within reach
• Chewing often decreases as the adult teeth finish coming in

Providing safe, appropriate chew toys is recommended by veterinarians to help puppies work through this normal developmental stage while protecting your household items.

3. Boredom and Lack of Enrichment

Dogs who spend long stretches of time with little to do frequently turn to chewing as a way to fill the gap. In these cases, the blanket is simply one of the easiest, most accessible targets.

Common signs boredom is a factor include:

• Chewing happens mainly when the dog is alone and under-stimulated
• There are few toys, puzzles, or interactive games available
• Daily exercise and mental enrichment are limited or inconsistent

Behavior organizations such as the ASPCA emphasize that increasing physical exercise and mental stimulation is a core part of treating destructive chewing behaviors.

4. Separation Anxiety and Stress

For some dogs, blanket chewing is more than a habit; it is a coping mechanism for anxiety. Dogs with separation-related problems or generalized anxiety may chew, suck, or shred blankets when they feel distressed.

Possible indicators that anxiety is involved include:

• Crying, pacing, or panting when you prepare to leave
• Chewing mostly when the dog is alone or at night
• Other signs of stress such as house soiling, drooling, or attempts to escape

The ASPCA notes that anxious dogs often engage in destructive chewing directed at doors, furniture, or bedding when left alone, reflecting attempts to cope or escape.

5. Hunger and Diet Changes

Some dogs begin chewing on blankets or bedding when their caloric intake is reduced or feeding routines change.

• The dog has recently started a weight-loss diet
• There is increased begging or food-seeking behavior
• Blanket chewing appears around usual meal times

While chewing fabric does not satisfy nutritional needs, a hungry dog may mouth or chew anything nearby in a general attempt to self-soothe or search for food. Review diet changes with your veterinarian to ensure your dog’s nutritional needs are still being met.

6. Medical Issues and Pain

Sudden or escalating chewing in an adult or senior dog can sometimes indicate an underlying medical problem. Pain, itching, or oral discomfort may drive a dog to chew more intensely than before.

Potential medical contributors include:

• Dental disease or fractured teeth
• Gastrointestinal discomfort or nausea
• Neurological issues or cognitive decline in older dogs

When chewing behavior changes abruptly, or is accompanied by other symptoms such as bad breath, drooling, weight loss, or behavior changes, a veterinary exam is strongly recommended.

Is Blanket Chewing Ever Dangerous?

Gentle, occasional chewing or sucking on a blanket is rarely harmful on its own. However, there are situations where the behavior becomes risky and needs prompt attention.

Ingesting fabric is the most serious concern. Foreign-body obstructions in dogs are well documented in veterinary literature and can require surgery to remove blocked material from the intestines.

How to Respond When Your Dog Chews Blankets

The goal is not to punish your dog for chewing, but to understand the cause and gently guide them toward safer, healthier alternatives. Leading welfare groups strongly advise against physical punishment or yelling, as these can increase fear and anxiety without resolving the behavior.

Step 1: Observe the Context

Start by keeping track of when and where blanket chewing occurs. Useful details include:

• Time of day (bedtime, when you leave, early morning, etc.)
• Who is present (alone vs. with family)
• Dog’s energy level beforehand (restless, bored, tired)
• Recent changes (new baby, move, schedule shift, diet change)

This pattern will help you and your veterinarian or behavior professional identify whether boredom, anxiety, hunger, or other factors are most prominent.

Step 2: Rule Out Medical Problems

If chewing is new, more intense, or occurs in an older dog, schedule a veterinary exam. A veterinarian can:

• Check for dental disease, mouth pain, or oral injuries
• Assess for gastrointestinal or metabolic issues
• Evaluate for pain in joints or spine that may cause restlessness
• Discuss diet, weight, and any recent health changes

Medical issues need to be treated first, or training alone is unlikely to succeed.

Step 3: Provide Better Chewing Options

Redirect your dog’s chewing to safe, dog-appropriate items. Animal welfare organizations recommend offering a variety of textures and types to keep your dog interested.

• Durable rubber toys and food-stuffable toys (e.g., Kongs)
• Dental chews approved by your veterinarian
• Puppy-safe teething toys for young dogs
• Frozen washcloths (supervised) for teething relief

Each time you catch your dog beginning to chew the blanket, calmly swap it for an approved chew and praise them when they engage with the new item.

Step 4: Increase Exercise and Mental Enrichment

Many dogs chew less destructively once their physical and mental needs are met. The ASPCA and other behavior resources highlight enrichment as a core part of reducing problematic chewing.

• Daily walks or runs appropriate to your dog’s age and health
• Interactive games like fetch, tug (with rules), or scent games
• Food puzzles and slow-feeding toys at mealtimes
• Short training sessions to practice cues and tricks

The more your dog’s brain and body are engaged in healthy activities, the less likely they are to default to blanket chewing out of boredom.

Step 5: Address Anxiety and Separation Issues

If your dog shows signs of distress when left alone or during specific triggers (storms, visitors, etc.), a behavior modification plan may be needed. This often includes:

• Gradual desensitization to departures and absences
• Creating a safe, predictable resting area
• Pairing departures with high-value food activities (where appropriate)
• In some cases, medication prescribed by a veterinarian or veterinary behaviorist

Guidelines for treating separation anxiety emphasize changing the dog’s emotional response to being alone rather than simply blocking access to chew targets.

Step 6: Manage the Environment

While you work on the root causes, smart management keeps your dog safe and protects your belongings.

• Remove or limit access to particularly tempting blankets when unsupervised
• Provide dog-specific blankets or beds that are sturdy and easy to clean
• Use chew-deterrent sprays on fabrics, if recommended by your veterinarian
• Confine your dog to a dog-proofed area when you are away

Some behavior experts note that, for chronic blanket chewers who ingest fabric, it may be safer to avoid blankets altogether and provide other kinds of comfortable resting surfaces.

When to Seek Professional Help

Not all blanket chewing requires professional intervention, but it is wise to consult your veterinarian or a qualified behavior professional if:

• Your dog swallows fabric or has vomited or passed pieces of blanket
• The chewing escalates quickly or appears almost compulsive
• There are clear signs of anxiety, fear, or aggression alongside chewing
• Your dog is injuring teeth or gums
• Home strategies have not helped after several weeks of consistent use

Board-certified veterinary behaviorists and credentialed trainers (such as those certified by recognized professional bodies) can design tailored, science-based treatment plans for complex chewing and anxiety problems.

Frequently Asked Questions (FAQs)

Q: Should I stop my dog from sucking on their blanket?

If your dog is gently sucking or nibbling, not ingesting fabric, and not distressed, it is often safe to allow the behavior as a comfort ritual. Monitor closely and redirect only if it becomes more intense, damaging, or obsessive.

Q: Is blanket chewing a sign of separation anxiety?

It can be. When blanket chewing occurs primarily when the dog is alone and is paired with other signs like vocalizing, pacing, or house soiling, separation-related distress is more likely and should be evaluated by a veterinarian or behavior professional.

Q: What can I give my puppy instead of the blanket?

Offer a variety of puppy-safe chew toys, including soft rubber chews, food-stuffable toys, and cooled teething toys, and rotate them regularly. Supervise your puppy and calmly trade the blanket for an approved chew each time they begin chewing the fabric.

Q: My older dog just started chewing blankets—should I be worried?

A sudden change in chewing behavior in an older dog warrants a veterinary exam to check for pain, dental disease, cognitive decline, or other medical issues. Once health problems are ruled out or treated, you can address any remaining behavioral components.

Q: Do bitter sprays really stop dogs from chewing?

Taste deterrent sprays can help some dogs avoid specific items, but they work best as part of a broader plan that includes enrichment, training, and management. Always choose products recommended by your veterinarian to ensure they are safe if licked or inhaled.
