Giselle, she said she can crate him, but would like to leave him out to look after the house.
I'm just glad he's not chewing on the Chinese Crested. That was a joke.
I'm thinking you may just need to crate him until he grows out of the puppy stage. That may be cheaper for you than replacing sofa cushions.

BTW - welcome to PT and we would love to see pictures of your family.
