Dogs' Sleeping Habits: Factors, Normalcy, and Health Concerns

Dogs, much like humans, sleep to recharge and restore their bodies. A study published in the Journal of Veterinary Behavior has found that dogs in a barren research facility slept more than those with environmental enrichment, highlighting the impact of environmental factors on a dog's sleeping habits [3].

Dogs sleep for various reasons, including conserving and replenishing energy, supporting growth and development (in puppies), and recovering from physical and mental activity [1]. However, their sleep needs can significantly vary based on age, size, breed, and activity levels.

Sleep Duration by Age, Size, and Breed:

  • Puppies: 18-20 hours
  • Adult Dogs: 12-14 hours
  • Senior Dogs: 16-18 hours
  • Large Breeds: 16-18 hours
  • Small Breeds: 12-14 hours
  • High-Energy Breeds: 10-12 hours
  • Working Dogs: 12-16 hours
  • Inactive Dogs: 14-16 hours

Dogs have more polyphasic sleep patterns, with less deep REM sleep than humans, contributing to their need for more total hours of sleep to recharge their brains effectively [3][5]. Inactivity or boredom can also cause dogs to nap more, and health issues like hypothyroidism can increase sleep needs [1][5].

Some breeds are known for being especially sleepy, like Basset Hounds, which can sleep 12-16 hours or more, especially as they age [4]. However, if a dog is sleeping excessively and has a clean bill of health, it may be due to boredom [3].

Abnormal Sleep Habits and Health Concerns:

Any noticeable change in a dog's routine or behavior warrants a discussion with a veterinarian to rule out underlying medical causes [4]. Abnormal sleep habits in dogs can indicate deeper health issues, such as sleep-disordered breathing, causing loud snoring and daytime drowsiness, especially in short-nosed and toy dog breeds [4].

Dogs with REM Sleep Behavior Disorder may twitch in their sleep and then pop up and start running, barking, or attacking [4]. A puppy falling asleep mid-play or mealtime could indicate canine narcolepsy [4]. A dog sleeping all day could be suffering from depression, diabetes, thyroid issues, or hearing loss [4].

If you suspect your dog's sleep health is abnormal, experts recommend getting your pup checked out as soon as possible [4]. It's crucial to ensure your furry friend is getting the rest they need to live a happy and healthy life.

  1. Dogs' need for environmental enrichment can impact their sleeping habits, as demonstrated by a study in the Journal of Veterinary Behavior that reported dogs in barren facilities slept more than those with enrichment.
  2. Mental health concerns, such as depression, can be indicated by abnormal sleep habits in dogs, like sleeping all day, and it's essential to consult a veterinarian to rule out underlying health issues.
