Undesirable behavior is possible among all canine breeds. Some dogs bark too much. Others are reactive. However, another frequently reported issue is destructiveness, which can include our clothes. While training, socialisation, and environment play a major role, genetics can also influence behavioral tendencies.1
Several possible reasons can explain why some dogs like dirty underwear. Many factors may be behind this unseemly behavior. You may be surprised to learn that you may unintentionally contribute to this behavior.

The 9 Possible Reasons Why Dogs Like Dirty Underwear
1. Affection for Their Owner
Every pet owner believes their pup loves them. It turns out that this assumption is probably true as dogs form strong bonds with their humans. Research has shown that familiar scents, like those of an animal’s keeper, activate an area of the canine brain associated with positive emotions and rewards. While comparisons vary, dogs are often thought to have emotional capacities similar in some ways to young children, experiencing emotions like excitement, fear, and attachment.
As distasteful as it may seem to us, your dog may view your dirty clothes as a sign of you and deem them worthy of attention. It may be a canine way of being close to you by interacting with these items, which can also provide comfort, although curiosity and play behavior can also play a role.
2. Security
By the same token, a dog may feel comforted by your scent. Hanging out with your dirty laundry may help calm a stressed or fearful animal. You may even find your dog sleeping on your clothes. After all, that’s when an animal is most vulnerable.
Having your scent around them may help your pet sleep better with this feeling of security.
3. Teething

Puppies will be puppies when everything is fair game, regardless of whether it’s appropriate or not. That includes your laundry. Everything goes into a pup’s mouth at that age. It’s a time of awareness when a dog is actively exploring its world. Luckily, it’s also a period when you can train a puppy and shift its attention from clothes to toys.
4. Just Another Toy
Dogs love playing with toys. For better or worse, some may resemble everyday household items, presumably to amuse pet owners more than the dogs. If your pet picks up and chews a piece of your clothing, it may be that they simply don’t know any better and prefer your underwear on the floor before another toy, due to familiar smells and rewarding textures, particularly if they haven’t yet learned which items are appropriate to chew.
5. They Like the Smell
Canines are better equipped in the olfactory department than humans. Their sense of smell is thousands of times more refined than ours, along with the brain area that interprets the signals. Your dog may be going after your underwear because they simply like the smell.
Their nose is giving them this information more so than their taste buds. Nevertheless, the result is the same.
6. Anxiety and Other Behavioral Disorders
Sometimes, inappropriate behavior has other causes that may warrant a vet visit. In some cases, repetitive or excessive chewing may be linked to compulsive tendencies or anxiety-related conditions. They often have complex underlying reasons instead of a simple lack of training on your part, which may include environmental and social stress, while genetics may play a part.
Treatment usually involves behavior modification and medication in some cases. Your pet may target your laundry simply because they happen to be around it.
Anxiety can cause many types of undesirable behavior, including destructiveness in cases of separation issues. Many things can trigger it, such as moving to a new home or changing your schedule. Remember the emotions we mentioned that dogs can experience, like stress and fear? They may drive your pet’s behavior. We recommend discussing the problem with a vet.

7. Resource Guarding
Some dogs are more territorial than others. It often depends on early socialization and training. If your dog is picking up or chewing your laundry, they may be guarding what they view as precious. It can occur if you bring home another pet.
The trick to curbing this behavior is redirecting your dog to more appropriate, high-value items and reinforcing commands like drop it or leave. It’s essential not to fuel the fire by leaving your clothes on the floor.
8. Boredom
Canines are intelligent animals. Daily mental stimulation is critical for their physical and mental well-being. The alternative is a bored dog, which is a recipe for disaster when it comes to your stuff. It can have serious consequences if your pet chews and swallows your clothing.
That could set the stage for emergency surgery to treat a gastrointestinal obstruction.
9. Nutritional Deficiency
Sometimes, chewing or ingesting unusual items can be linked to underlying health issues such as nutritional imbalances or gastrointestinal problems, although behavioral causes are more common. If your pet’s obsession with your clothes is something new, we recommend taking your pup to the vet to rule out an underlying medical condition that is at the root of the behavior.

Correcting the Unwanted Behavior
Discussing the situation with your vet can help determine what triggers this bad habit and figure out a way to remedy it. We suggest looking for any patterns in the behavior that may be the cause. Also, consider any changes to the regular routine that may be stressing your dog. If your vet has ruled out medical reasons, they may suggest behavior modification techniques.
Of course, an important way to stop this habit is by keeping your laundry off the floor. Don’t invite problems by making it easy for your pet. If you suspect your pet is bored or anxious, provide them with plenty of exercise and toys to occupy their time.
Interactive games, agility, and scent work will engage your dog and provide mental stimulation or enrichment. Long walks or a session at a doggy park can give your pup plenty of opportunities to sniff to their heart’s content.

Conclusion
Some dogs are chewers. They’ll pick up anything they see. However, it’s a risky behavior that can have serious health consequences if your dog swallows pieces of clothing. Therefore, it’s vital to identify the triggers and correct this habit.
We also suggest instructing your children to pick up their clothes to prevent this behavior.
