How many hours a day should my corgi mix sleep? He's approximated to be a year old, and he may be mixed with sheepdog or dachshund, not sure.. He seems to sleep a lot tho! On the weekends I walk him around 7 pm, he's in bed by 9 and wakes me up at 8:30 in the morning for a walk, then he'll sleep some more. I'd say he sleeps 18 hours a day? If we keep him up with more walks and playing and stuff he'll stay up and play, but then when we're done playing he runs back under the covers and naps!
