Curtail dog

Cur´tail dog`

    (dǒg`; 115)
1.A dog with a docked tail; formerly, the dog of a person not qualified to course, which, by the forest laws, must have its tail cut short, partly as a mark, and partly from a notion that the tail is necessary to a dog in running; hence, a dog not fit for sporting.
Hope is a curtail dog in some affairs.
- Shak.
