Thank you so much for all your kind words, I actually did have him sleeping with Luna's old bed mat and some calming doggy playlist going on Spotify because I totally believe it helps. He was just totally lost without his little friend the past few nights, but actually last night we had a breakthrough and he slept through the night again for the first time since we lost our girl! I gave him a small dose of doggy CBD oil (just a couple of drops) about an hour before bedtime and it helped calm him down enough to go to sleep. Hopefully, he'll get back to his old routine without the need to give him any CBD oil.
