My Dog Subtraction

You should meet,
My dog,

The main attraction,
Not named Minus,
Not today,
Never called
Take Away,
2 snouts,
3 ears,
3 eyes,
Filled with tears,
5 legs,
2 tails too,
Subtraction dog,
What did he do?
Took away,
One of each,
At least the things,
Within his reach...
Now my dog,
Looks real fine,
2 eyes, 2 ears,
Just like mine...
Subtraction sit!
Here's your treat,

Hold them with,
5 dog feet...
