Chewing/Gnawing in Dogs

Chewing/gnawing in dogs, also referred to as “nibbling”, is a behavior that dogs can exhibit for various reasons. Current research is examining the neurological and behavioral psychological aspects of this symptom. Studies show that chewing/gnawing is often a sign of stress or boredom. Researchers at the University of Helsinki have found that dogs who frequently chew/gnaw on objects or their own body parts often have higher cortisol levels, which indicates stress. This suggests that chewing/gnawing may be a coping strategy for stressful situations.

Another area of research focuses on the genetic factors that contribute to chewing/gnawing behavior. A study by Cornell University has shown that certain dog breeds are more likely to chew/gnaw on objects due to their genetic predisposition. These breeds often have a long history as working or hunting dogs and may exhibit this behavior as a legacy of their ancestors, who had to manipulate objects to perform tasks. Research in this area aims to understand how genetics and environmental factors interact to influence this behavior.

Behavioral researchers are also investigating the role of social interaction in the development of chewing/gnawing behavior. Some studies, including one from the University of Vienna, suggest that dogs who live in social groups or interact regularly with other dogs are less likely to engage in excessive chewing/gnawing. This may indicate that social isolation is a reinforcing factor for this behavior. The researchers hope to positively influence chewing/gnawing behavior through targeted social interactions and play activities.

Another aspect of current research is the investigation of chewing/gnawing behavior as an expression of curiosity and exploratory behavior. Dogs, especially puppies, often explore their environment by chewing/gnawing, which is considered normal and healthy. Researchers at the University of California, Davis, have found that chewing/gnawing in young dogs is often associated with the development of cognitive skills and the exploration of new environments. These findings are being used to develop training programs that promote the natural exploratory behavior of dogs while minimizing unwanted chewing/gnawing.

Nutrition also plays a role in the chewing/gnawing behavior of dogs. A recent study by the University of Liverpool suggests that deficiencies in the diet, particularly a lack of certain minerals and vitamins, can lead to increased chewing/gnawing. The researchers recommend a balanced diet to minimize the risk of nutrition-related chewing/gnawing. They are currently investigating how specific nutrients affect the behavior of dogs and whether dietary adjustments could be an effective intervention against excessive chewing/gnawing.

Finally, some researchers view chewing/gnawing as a potential sign of underlying health problems. A study by the Royal Veterinary College in London has shown that dogs who suffer from chronic pain are more likely to chew/gnaw on their paws or other body parts. This could be an attempt to relieve the discomfort. The researchers are working to develop diagnostic methods to determine when chewing/gnawing is a symptom of a serious health problem and when it is a harmless behavior.
