Right, because the evaluation of the expression 'my dog' fails so it
returns the whole thing. That doesn't make it a valid expression.
Some other interesting behavior in HyperCard:
the value of "3 + my dog" -- works, returns exact string
the value of "3 + my" -- fails, because "my" isn't a number
This seems to me to be inconsistent, albeit maybe convenient in some
situations.
As for my earlier statement about the end-of-line behavior, turns out
even I don't understand it. It only works with some commands:
set the name of button 1 to my dog -- works, sets name to 'my dog'
put my dog -- fails, because 'my dog' is not a valid expression
