Dogs are human's most loyal companions, and they bring us endless joy and companionship. But did you know that the shape of a dog's head is closely related to the quality of his sleep?A new study has revealed this little-known secret for us.
Head shape classification: short, medium and long
The head shape of dogs is a selection and breeding of humans, and there are significant differences. The researchers classified by calculating the cranium index, which is the ratio of the width of the head to its length. The index is less than 50 for the short head, 50-60 for the middle head, and more than 60 for the long head.
Brachycephalic dogs face sleep disturbances
A team of researchers from the University of Etveş Rolland in Hungary conducted an in-depth survey of 92 family dogs. It was found that dogs with short heads had shorter non-REM sleep and longer REM sleep than medium- and long-headed dogs. This could mean that brachycephalic dogs spend less time in deep sleep, while REM sleep for too long may be linked to decreased learning and brain health issues.
Brachycephalic dogs have abnormal brainwave patterns
Even more surprisingly, the researchers also found that brachycephalic dogs had significantly different brainwave patterns during REM sleep than dogs with medium and long heads. Brachycephalic dogs have fewer waves and more delta waves, a pattern that is often associated with decreased learning and brain health issues.
The influence of human choice
Researchers speculate that brachycephalic dogs may have retained their puppy sleep patterns due to human selection, which may have had an impact on brain function. At the same time, it also suggests that breeding in order to create shorter, flattened faces may have had deleterious changes in the brain function of brachycephalic dogs.
How to improve the health problems of brachycephalus?
When it comes to the health of brachycephalic dogs, we need to consider solutions from multiple perspectives. First of all, owners should pay attention to the quality of their dog's sleep and ensure that they get enough time for deep sleep. Secondly, veterinarians should also strengthen the brain health monitoring of brachycephalic dogs to detect and deal with potential problems in a timely manner. In addition, for breeders, more attention should be paid to the impact of breeding on the health of dogs, and avoid excessive pursuit of certain physical characteristics at the expense of their health.
Summary: Head shape is closely related to your dog's sleep quality and brain health
This study sheds light on the impact of head shape on a dog's sleep quality and brain health. Brachycephalic dogs are at greater risk and require more attention and care from us. At the same time, it also reminds us that in addition to appearance and personality, the shape of the head and health should also be important considerations when choosing a pet dog. Let's work together to create a healthier and happier living environment for our dogs!
