Three dogs by E. C. Brereton poem

I know a dog called Isaac,
Who begs for cake at tea;
He's fat and white and most polite,
And belongs to Timothy.

I know a dog who carries
His master's walking-stick;
He's old and slow, and his name is Joe,
And he belongs to Dick.

I know a dog called Jacob,
The best of all the three,
Sedate and wise, with nice brown eyes,
And he belongs to Me!
