The Best Dog's Friend | final version

Look, a dog lies on the couch
Texting Master thus to grouch:
"I am now extremely slow
Cats gave me in football blow.
So I'd like to munch a brunch
Bring my bowl with food to crunch".
Master gets up from his bed
Wanting his dog to be fed
He works for his pet to thrive
For his pet dog he does strive
This pet cost him quite a lot
Neither shout to dog nor swat
He fulfills pet's every wish
Bringing himself on a dish.
