Spenser, Bubba, Ruby and the pet sitter

Is Spenser allowed on the couch on the porch?  I got to your place, fed them all and sat down on the couch to read.  I had my coffee and a book so I was good to go!  I'd let all of the dogs in the porch and after Spenser finished eating he crawled up beside me.  Seemed as though he'd been up there before????  :)  Ruby and Bubba both just wanted to be rubbed so I did.  They're all doing just fine!
