2. A dog is said at common law to have no intrinsic value, and he cannot therefore be the subject of larceny. 4 Bl. Com. 236; 8 Serg. & Rawle, 571. But the owner has such property in him, that he may maintain trespass for an injury to his dog; "for a man may have property in some things which are of so base nature that no felony can be committed of them, as of a bloodhound or mastiff." 12 H.

4. When a dog, in consequence of his vicious habits, becomes a common nuisance, the owner may be indicted. And when he commits an injury, if the owner had a knowledge of his mischievous propensity, he is liable to an action on the case. Bull. N. P. 77; 2 Str. 1264; Lord Raym. 110. 1 B. & A. 620; 4 Camp.

5. A man has a right to keep a dog to guard his premises, but not to put him at the entrance of his house, because a person coming there on lawful business may be injured by him, and this, though there may be another entrance to the house. 4 C. & P. 297; 6 C. & P. 1.
