restless nights

Question
We adopted a 9yr Siberian who is in excellent health accoring to our vet.  We give him 1 1/2 to 2 hours of walking through the woods exercise every day.  In the winter he likes to pull a dog sled(retired sled dog we were told).  He eats a +30% protein kibble diet and does not seem to drink excessively. But he can not seem to sleep the whole night thru, getting up multiple times to go out,either to lay or go to the bathroom and just hang out outside.  He does sleep a fair amount through the day, but we consider this normal for his age.  Would getting another husky buddy help him energy/sleep wise?

Answer
A buddy will help, yes. I can also tell you a Husky never feels old if he sleeps during the day he will sleep less at night. Looking at his age I would get a blood panel done just to check on his, Thyroid heath but also do a diabetes test.
Any further Q's please ask!
