Dogs gnaw on blankets for a handful of reasons, ranging from completely normal self-soothing to signs of anxiety or a medical issue worth investigating. The most common causes are teething (in puppies), comfort-seeking rooted in early weaning, boredom, stress relief, and occasionally a compulsive disorder. Understanding which one applies to your dog depends on when the behavior started, how intense it is, and what else is going on in their life.
Teething in Puppies
If your dog is under a year old, teething is the most likely explanation. Puppies are born without teeth, but a full set of 28 baby teeth comes in by about 8 weeks. Between 4 and 7 months, those baby teeth fall out as 42 adult teeth push through the gums. That process creates real discomfort, and gnawing on soft, yielding surfaces like blankets gives puppies something to press their sore gums against.
This stage wraps up around 6 to 7 months once the adult teeth are fully in place. In the meantime, offering a mix of rubber chew toys and soft toys helps redirect the behavior. Frozen treats like blueberries, carrots, or seedless watermelon can also soothe inflamed gums. If the blanket gnawing stops once your puppy’s adult teeth settle in, it was almost certainly teething and nothing to worry about.
Comfort Suckling From Early Weaning
Adult dogs that gnaw, suckle, or knead blankets are often replaying a behavior from puppyhood. Animal behaviorists believe dogs that didn’t get enough comfort nursing as young puppies are more likely to seek that sensation later in life. This happens when puppies are separated from their mother too early, when the mother was unwell, or when the litter was bottle-fed by humans. The blanket becomes a stand-in for the warmth and rhythmic motion of nursing.
Some dogs even knead the fabric with their front paws before settling in to suckle, much like cats do. This is generally harmless and self-limiting. Many dogs only do it when they’re winding down for sleep or feeling relaxed. If it stays at that level, it’s simply a comfort habit.
Stress, Anxiety, and Boredom
Chewing triggers the release of endorphins, the same feel-good hormones that give humans a sense of calm after exercise. For dogs, repetitive gnawing works like a natural stress valve. A dog that’s understimulated, left alone for long stretches, or dealing with changes in their environment may turn to blankets because the act of chewing genuinely makes them feel better.
The key question is whether the chewing is casual or frantic. Dogs with separation anxiety typically chew most intensely when left alone, and the blanket gnawing comes alongside other signs: whining, barking, pacing, restlessness, or house soiling. If your dog only shreds blankets while you’re away and seems distressed rather than content, anxiety is the more likely driver. A dog that lazily gnaws a corner while lounging next to you is probably just bored or self-soothing.
Breed Tendencies and Compulsive Behavior
Certain breeds have a genetic tilt toward sucking and gnawing behaviors. Doberman Pinschers are the most well-documented example. Flank sucking, where the dog suckles its own side, is almost exclusive to the breed and appears to be an inherited temperament trait. Many Dobermans engage in this without it ever becoming destructive, but in some individuals it escalates. Dachshunds and other breeds with strong oral fixation tendencies can also gravitate toward blanket gnawing more than average.
When any repetitive behavior becomes so intense that a dog can’t stop on their own, performs it out of context, or does it to the point of self-harm or property destruction, veterinarians classify it as a compulsive disorder. To qualify, the behavior must occur without any underlying skin, neurological, or other medical condition explaining it. True compulsive disorders are relatively uncommon, but they do require professional behavioral intervention rather than simple redirection.
Nutritional Deficiencies and Pica
Occasionally, dogs chew and swallow non-food items because of a condition called pica, which can be driven by mineral or nutritional deficiencies. A dog that is actually consuming the blanket fabric, not just mouthing it, warrants a closer look. UC Davis School of Veterinary Medicine notes that ruling out an underlying medical problem is an important first step, since some animals eat unusual materials when their diet is incomplete. Your vet can run bloodwork to check for deficiencies and assess whether a dietary change resolves the behavior.
When Blanket Gnawing Becomes Dangerous
The real risk isn’t the chewing itself but swallowing the fabric. Ingested textile material is a recognized cause of gastrointestinal obstruction in dogs, and it qualifies as a medical emergency. Symptoms of a blockage include repeated vomiting, abdominal tenderness, restlessness, constipation, and straining to defecate. These signs can develop suddenly or build over days. If your dog has been eating pieces of blanket and starts showing any of these symptoms, they need veterinary attention quickly. Imaging is the primary tool for confirming a blockage and determining the best course of treatment.
Redirecting the Behavior
The first practical step is limiting access. For a few days, store blankets out of reach or use baby gates to keep your dog away from the rooms where blankets live. This breaks the cycle of reinforcement while you introduce better alternatives.
Replace the blanket with durable rubber toys, ropes designed for chewing, or stuffed food puzzles. A rubber toy filled with xylitol-free peanut butter and frozen makes a particularly effective substitute because it engages your dog’s mouth for an extended period. Rotate toys weekly so they stay interesting.
Positive reinforcement does the heavy lifting here. When your dog picks up an appropriate chew toy instead of a blanket, reward them immediately with a treat and enthusiastic praise. Teaching a solid “leave it” command adds another layer of control. Start by holding a treat in your closed hand, waiting for your dog to back off, then rewarding them from your other hand. Gradually practice this near blankets as they build the habit of disengaging on cue.
For dogs whose gnawing stems from boredom or insufficient exercise, increasing daily activity often resolves the problem on its own. Two 30-minute walks a day combined with puzzle feeders at mealtimes can dramatically reduce destructive chewing within a few weeks. Deterrent sprays applied to blankets can help in the short term, but they work best as a supplement to training and enrichment rather than a standalone fix.
Choosing Safer Bedding for Chewers
If your dog is going to gnaw no matter what, the bedding material matters. Ripstop and ballistic nylon fabrics are the most resistant to tearing. Beds with aluminum or reinforced plastic frames hold up better than soft, free-standing options. For crate beds, look for firm closed-cell foam covered in a waterproof outer layer with heat-sealed edges instead of zippers or stitching, since exposed seams are the first thing most dogs target. Tightly woven covers on padded beds work well for light to moderate chewers, though persistent chewers will eventually find a way through anything that isn’t specifically engineered to resist them.
