The song is extremely romantic and highly symbolic like most oldies. It is about an issue that always stays at the forefront of Tina’s thoughts. Obviously, she is having a good time as she hasn’t lost her lover or anything. We often say ‘as deep as a river’ and ‘as high as a mountain’ to reckon the measure of an emotion that we truly feel in the most poignant manner and, since the idea is the very title of the song, we can safely assume that Tina is underlining the profundity of her emotions for her man, by placing the issue on the title of the song where it is very noticeable.
In the first stanza, Tina uses the imagery of a rag doll which means that she used to be a poor girll and her only toy was the rag doll, but it being a useless rag doll did not prevent her from cherishing it. By this she implies that she’d cherish her lover even if he is poor and unlucky. Now that she is grown up and her love is no longer simple like childhood love but has grown stronger and more complicated. The second imagery that she uses is that of a puppy which always follows its master, a boy, faithfully. Here it means that she’d always follow him through life loyally and faithfully like a dog, no matter what happens, even if it might seem blind and foolish to others.
Like every person who is head over heels in love, the fear of losing her lover looms high in the horizon. Here, Tina is confident that her man wouldn’t jilt her, but the probability is always there dangling before her, to be feared
