This is a love song for people, dogs, dogs who love people, and people who love dogs. The singer is ambiguous as either the dog or the man singing to his mistress.
Lyrics
Why do you treat me like a dog You make me fetch you this an fetch you that You exercise me so I don't get fat Sometimes you treat me like a dog
Why do you treat me like a pup You scratch behind my ears and pat my nose You pour me water from a garden hose Sometimes youn treat me like a pup
I always hang around worship the ground you walk I'm always at your feet you give me treats Sometimes you let me talk
Why don you treat me like a pet You brush and comb my hair so lovingly ou trim my whiskers and you pamper me Sometimes you treat me like a pet
