Both our GSDs, Jax and Kane, sleep in the bedroom with us at night. They have their crates in there but Kane doesn't sleep in his anymore, preferring the floor on my side of the bed instead. DH would really like it if Jax would sleep on the floor on his side of the bed, but Jax refuses to. DH wears a CPAP apparatus at night and the oxygen concentrator machine is on DH's side of the bed. I think the noise the O2 machine makes bothers Jax, so Jax sleeps in his crate with the door open; or rarely, on my side. The last four nights in a row, Jax has woken up in the middle of the night. He makes a quiet "woof" and it gets louder as he heads to the living room. Woof, woof and then flat out barking. I tell him "it's okay Jax or Nein". Jax then comes back to the bedroom, goes to Dad's side of the bed to nuzzle and check on him, then to my side of the bed for the same thing, he sniffs Kane to check on him, then he goes back to his crate to lay down. Last night he insisted on checking on the cats too, where they were asleep at the foot of the bed; much to the cats dismay. We can't figure out what's getting him up in the night. Dreaming, maybe? It doesn't bother me, since I rarely sleep deeply anyhow and it doesn't wake DH up at all. Just curious.
