If Dr. Seuss were a vet

I was recently sent this poem. I have tried to find who the author is but to no avail; however, it is practically perfect.












I won't dispense it, Sam I am....
I won't dispense without exam.

I won't dispense it to your dog,
Although you'll bash me in a blog.

I won't dispense it to your friend,
Who yells at me without an end.

I won't dispense it for the ear,
For the eyes, or for the rear.

I won't dispense it though you yell,
How mean I am - the world you'll tell.

I won't dispense it to your cat,
To your bird, or to your rat.

I won't give in - I'm standing tell,
Although you'll whine and cry and call.

I won't dispense it, Sam I am,
You can't have meds without exams!
