Why Does My Dog Eat Used Tissues? Understanding the Unusual Canine Behavior

Dogs are fascinating creatures with behaviors that can sometimes leave their owners scratching their heads. Among the many quirky habits our furry friends exhibit, the consumption or tearing up of used tissues ranks high on the list of puzzling actions. If you’ve ever wondered, “Why does my dog eat used tissues?” you’re not alone. This comprehensive guide aims to shed light on this unique behavior and offer guidance on how to manage it.

Exploring the Canine Palate

To begin, let’s remember that dogs experience the world primarily through their sense of smell. To a dog, a used tissue is not just a piece of trash – it’s a smorgasbord of scents. Tissues often hold residues from human bodily fluids like mucus, tears, saliva, and even sweat, all of which carry unique smells. For our furry companions, these scents can be intriguing, if not irresistible.

  1. Evolutionary Perspective: In the wild, canines are scavengers, always on the lookout for anything that might be a source of nutrition. A tissue with human residue might trigger their instinctual interest, leading them to investigate and sometimes consume it.
  2. Taste and Texture: Beyond the scent, the texture of tissues might be appealing to some dogs. The soft, pulpy nature can be pleasurable to chew on, much like certain dog toys.

The Role of Behavior

Sometimes the consumption or shredding of tissues has less to do with the tissue itself and more to do with a dog’s behavioral tendencies.

  1. Boredom: Dogs that aren’t mentally or physically stimulated might find pleasure in the act of tearing things apart, including tissues. It’s their way of self-entertaining.
  2. Attention-seeking: If a dog learns that grabbing and tearing a tissue gets a reaction from its owner, it might repeat the behavior to seek attention.
  3. Anxiety and Stress: Dogs, like humans, can suffer from anxiety. For some dogs, chewing on items like tissues can be a coping mechanism.

Potential Health Impacts

While eating a tissue occasionally might not be harmful to most dogs, there can be some concerns.

  1. Digestive Issues: Consuming too many tissues can lead to potential blockages in a dog’s digestive system. It’s essential to keep an eye on their bowel movements and watch for signs of distress.
  2. Toxins and Chemicals: Some tissues contain lotions, fragrances, or other chemicals which can be harmful if ingested in large quantities.
  3. Infectious Agents: If the tissue was used by a sick person, there’s a slight risk of transmitting some pathogens, although it’s relatively low.

Managing the Behavior

If your dog has developed a fondness for tissues, consider these strategies:

  1. Keep Tissues Out of Reach: The simplest solution is often to keep tissues and waste bins out of your dog’s reach.
  2. Increase Mental and Physical Stimulation: Engage your dog in more playtime, walks, and training sessions. Interactive toys can also help keep their minds occupied.
  3. Training: Teach your dog commands like “leave it” or “drop it” to deter them from grabbing undesired items.
  4. Consult a Vet or Behaviorist: If the behavior becomes obsessive or if you notice any health issues, it’s essential to consult with a professional.


The act of dogs eating or tearing up used tissues can be baffling for many pet owners. While there’s a blend of instinctual and behavioral reasons behind this, understanding the motivations can help in managing and possibly redirecting the behavior. As always, prioritizing your dog’s health and well-being is essential, so remain vigilant and proactive in addressing any unusual habits.
