Funny story...when Angel was a puppy, she was OK going up stairs, but couldn't come down.
I had the same issue with Sadie and Ginny when they were puppies. Its so much more scary going down than up. They got it eventually though with some encouragement and help from mama.

Treats on the stairs is definitely the way to go. When he's more comfortable and has to learn to go down the stairs use lots of praise and encouragement and also stay close by his side. My two seemed to feel MUCH better about trying when I was close by or had a hand on them.
