Why Does My Dog Twitch In Their Sleep?
Dogs twitch in their sleep for many reasons.
In general, you should not worry when your dog twitches in their sleep. Brief, intermittent twitching in your dog’s sleep is completely normal — and yes, your dog is dreaming, likely about the experiences of their day.
What does it look like when a dog twitches in their sleep?
When your dog twitches in their sleep, they may kick lightly at the air with a back leg, or a front limb may twitch. Sleep twitching usually happens in a dog’s legs, but they may also move their head or wag their tail. Usually, dogs are lying on their sides when twitching and may even move more than one paw in a paddling motion. You may also notice your dog’s eyes moving behind their closed lids, irregular breathing, and even vocalizing, like whimpers, low growls, or soft barks.
Is twitching during sleep harmful to my dog?
In most cases, twitching during sleep is completely normal for dogs and can happen during the rapid eye movement (REM) stage of sleep. During REM sleep, a part of the brain called the pons controls muscle movement, and sometimes it’s ineffective, leading to twitching. These small muscle spasms are more frequent in puppiesopens in a new tab, who have less developed brains, and in senior dogs.
So, if you notice your dog keeps twitching in their sleep, don’t wake them and interrupt their deep snooze. You only need to worry if twitching becomes violent or lasts longer than 30 seconds.
Stages of a Dog’s Sleep Cycle
Dogs have the same sleep cycle as humans, just in a much shorter time frame. Researchers have found that the canine sleep cycleopens in a new tab includes an average of 12 minutes of non-REM sleep followed by six minutes of REM sleep. Compare this to 90 minutes of non-REM sleep followed by 60 minutes of REM for humans.
During REM sleep, dogs dream just like humans. Their breathing becomes shallower and more irregular, and their eyes might move behind their closed lids (this is where the “rapid eye movement” name comes from). Because dogs sleep significantly more than humans — about 12 to 14 hours a day — they’re moving through the sleep cycle multiple times, shifting in and out of deep sleep and puppy dreams, which can often lead to twitching
Do dogs dream?
While a dog sleeps, whether for a quick nap or a long, overnight snooze burrowed under the coversopens in a new tab, their brain processes the things they’ve seen and experienced throughout their day in dreams. Scientists know this because dogs have similar sleep patterns to humans, and their brains go through the same stages of electrical activity observed in dreaming humans.
We can’t know exactly what dogs dream about, but researchersopens in a new tab have observed some breeds performing behaviors specific to their breed. For example, sleeping Pointers tend to point! It’s most likely that a dog dreaming thinks about what they do during the day, like playing, going on walks, or snuggling with their favorite humanopens in a new tab.
