He lived in my house in a large crate - not a big dog. I gave him an old quilt. That helped also and a stuffed cat that purred, wind up too. The clock ticked the longest. The cat not so much.
It took a while but he got over his fear.
The clock ticked all night and day. The cat only when I had to leave.
I also gave him a bath towel covered in my scent. I think the combo worked.
Good luck candle lit for all.
