Sleep Disorders
Sleep disorders are uncommon in dogs, but they do occur. An inherited
condition seen most often in Doberman pinschers, Labrador retrievers,
beagles, and poodles--is characterized by sudden bouts of sleep at
inappropriate times, such as during play or mealtimes. Scientists don't
know exactly what causes sudden loss of muscle control resulting in
collapse, but the condition can be managed (though not cured) with
mediation. If you suspect your dog has "Sleep Disorders", videotape its
behavior at home and show the video to your veterinarian.
Sleep apnea is the same condition as in humans, in which a dog
intermittently stops breathing while sleeping because its soft palate
blocks its airway. Dogs with the condition don't sleep soundly because
their slumber is frequently interrupted as they gasp for air. Snoring is
common with sleep apnea, but not all dogs that snore have this disorder.
Obese dogs are predisposed to sleep apnea because their soft palate may
enlarge with fat buildup. Sleep apnea is also fairly common in
short-nosed dogs like bulldogs and pugs because their soft palates are
often oversized. Although there are no current medications to help
relieve sleep apnea, the current treatment of choice is surgery to trim
the soft palate. Dogs also can have REM (rapid-eye-movement disorder).
A sleeping dog in the REM phase of sleep does not experience the muscle
relaxation typical of REM sleep. Instead, the dog thrashes about
wildly--even though the animal is fast asleep. Dogs risk injuring
themselves in such a state, so scientists are looking into biochemical
treatments for this disorder. |
