Dogs and cats do tend to sleep more in the wintertime as temperatures get colder outside. This extended sleep helps them conserve energy.
Yes
The drop in temperatures signals their bodies to conserve energy because hunting/finding food takes more effort in cold weather.
Why
Shorter daylight hours in winter also signal pets' bodies that it's time to sleep longer. Lack of exercise due to cold weather plays a role too.
Other Factors
Most dogs sleep 12-14 hours in normal weather but may sleep up to 18 hours per day in the winter months.
How Much More
The amount of additional sleep may vary, but winter weather clearly causes an increase in sleep duration for most pets
Big Difference
The extra sleep pets get in winter allows their bodies to restore and repair which supports good health.
Benefits
Make sure pets have warm, draft-free spaces to sleep in winter. Provide extra bedding and consider a companion animal to cuddle with for warmth!
