In Which I Dither Over Doggies... Yes, Doggies, Plural

For 'tis a truth well known: a single girl
Who owns a house and has a single dog
Must need another one. So do unfurl
The arguments in favor. Lost in fog,
As far as all my friends would be concerned
Are any thoughts of feeding, walking or
Transporting two dogs in my car. I've learned
That border collies like each other more
Than they like anybody else. And yes,
The dog proposed to join us is one, too.
My Molly is a sweetheart. I confess
To guilty feelings that the times are few
When she has company. My hours are long
At work; I often feel I've done her wrong.
