| he's a puppy, he's full of energy so make him use it.
Have you been leaving him at home all day alone? If so he's probably sleeping all day and his zarcadian rhythm is all messed up. Is it possible to have someone come and check in on him during the day, maybe take him out and play with him during the day?
Also I'd suggest walking him as much as you can everyday. Dogs like exercise and really need it to stay calm and when they're young playing with them just isn't enough.
If neither of those things work, get him a crate if you haven't already, put it on the opposite end of the house, put a towel over it so he can't see out, and then go to bed.
He'll cry at first but eventually he'll get used to it, also put some toys in with him too to keep him entertained if he does stay up.
Remember he's just a puppy and he wants attention, so give it to him and keep him active during the day so he sleeps at night. |
