the dog's character: "he loves not him that loves not you"

In an 1804 miscellany on the dog, the mysterious "Another Author" speaks eloquently on all good things fido.

THE DOG'S CHARACTER,
by ANOTHER AUTHOR, IN VERSE.

The Dog, of all the quadrupeds,
For sport and faithfulness exceeds;
Of all the beasts, he best attends,
His master, and with care defends;
Does what he's bid, and tho' he's beat,
Submissive lays him at his feet,
So soon he can his wrongs forget.
Nay, tho' he's driv'n away with spurns,
With wagging tail he still returns
When you his excellence display,
He's sensible of what you say,
And in dumb show his thanks will pay.
Whene'er you fail, he goes on board,
And when you swim, he takes the ford:
Pursues you thro' the boist'rous waves,
Nor in the horrid tempest leaves.
With you o'er rugged mounts he goes,
.And guards you thro' a host of foes,
But to your friends due fondness shews.
Still all the day he keeps in view,
Nor is he in the dark less true,
He loves not him that loves not you.
Thro' all the labours of the wood,
He toils to make your pastime good;
Runs down for you the nimble hare,
And in his mouth untorn does bear;
Pursues all game, thro' brush and brake,
Not for his own, but master's sake.
When you repose, he couches by,
Or bears his chain contentedly:
Your house's and your poultry's guard,
Drives thieves and foxes from your yard,
In sleep secure your household store,
He barks all treachery from the door.
He asks no dainty bit, or cup
Profuse, to keep his spirits up.
Content the humblest food to lick,
A crust to gnaw, or bone to pick;
Whom would not such cheap servants please!
Who would not love such friends as these?
