         Researchers tested a new method of diagnosing sleep-disordered   
         breathing in dogs using a neckband developed for human sleep apnea   
         diagnostics. The study revealed that sleep-disordered breathing   
         is more prevalent among short-snouted dogs than those with longer   
         snouts.

   FULL STORY   
   ==========================================================================   
   University of Helsinki researchers tested a new method of diagnosing   
   sleep- disordered breathing in dogs using a neckband developed for human   
   sleep apnoea diagnostics. The study revealed that sleep-disordered   
   breathing is more prevalent among short-snouted dogs than those with   
   longer snouts.   
      
   French bulldogs, pugs and other brachycephalic dog breeds are popular   
   pets.   
      
   Brachycephalic dogs are shorter-nosed and flat-faced as a result   
   of breeding, making them more susceptible to heat, overexertion and   
   respiratory problems.   
      
   In addition, brachycephalic dogs have been found to suffer from recurring   
   episodes of sleep-disordered breathing, resembling human obstructive sleep   
   apnoea caused by upper airway obstruction. During such episodes, normal   
   breathing is interrupted by obstructed airways as the muscles of the upper   
   airways relax, resulting in sleep interruptions and daytime fatigue. Sleep   
   apnoea can have a dramatic impact on both human and canine wellbeing.   
      
   "Sleep apnoea places people at considerable risk of conditions such as   
   hypertension and cardiovascular disease. Sleep affects the body's immune   
   system, hormone secretion and metabolism. Sufficient, sound sleep is vital   
   for quality of life. For these reasons and others, we are interested in   
   canine sleep too," explains Doctoral Researcher Iida Niinikoski of the   
   University of Helsinki's Faculty of Veterinary Medicine.   
      
   "Previous methods for investigating sleep apnoea have required dogs to   
   sleep either while connected to all sorts of equipment or within a certain   
   type of box in a lab. This has made research challenging and limited   
   our knowledge of dog sleep apnoea."  The University of Helsinki Lung   
   Insight research group investigated breathing during sleep in dogs using   
   a neckband system developed originally for diagnosing human sleep apnoea.   
      
   The group measured breathing during sleep using the screening device in   
   the dogs' home environment. Brachycephalic dogs recorded a much higher   
   number of sleep-disordered breathing events than dogs with longer   
   snouts. The short-nosed dogs also snored more than their long-nosed   
   counterparts.   
      
   The neckband system was found to be an easy-to-use method for measuring   
   sleep- disordered breathing. Although its use is currently limited   
   to patients involved in research, in the future it may provide novel   
   opportunities for dog sleep apnoea diagnostics in other contexts too.   
      
   Next, the research group will explore factors predisposing dogs to   
   sleep apnoea.   
      
   As Niinikoski believes, "Good sleep is vital for the health of both   
   humans and our animal friends."
