The complaint does not expressly charge that the defendant was guilty of negligence in the care or keeping of his vicious dogs, and this omission is the ground of the demurrer to it. The plaintiff claims that tlie keeping of a dog known to its owner to he vicious and accustomed to attack and bite mankind is a nuisance, and that it is unnecessary to charge negligence.
A vicious dog running at large is a nuisance, because dangerous to mankind.
It follows that whoever keeps such a dog and allows him to be at large maintains the nuisance. Stated as above, it would seem to follow that in order to charge the master of the vicious dog with liability, the complaint should state that he allowed the dog to run at large.
But the authorities authorize the proposition to be stated in such way as to put the burden upon the master of showing that lie-securely kept his vicious dog.
Thus, a vicious dog is a nuisance except when securely kept from biting mankind.
If a vicious dog bites a person the presumption is that he was not securely kept. (Brice v. Bauer, 108 N. Y. 428.)
If these propositions are correctly stated, then the complaint need not negative the exception, but it must be alleged in the answer.
We think the clear weight of authority in this State is in favor of the sufficiency of this complaint. (Kelly v. Tilton, 3 Keyes, 263; Muller v. McKesson, 73 N. Y. 195; Lynch v. McNally, Id. 347.) It is true that in none of these cases did the question arise upon the sufficiency of the pleadings, and that in each one of them it affirmatively appeared that the owner of the vicious dog failed to securely keep him. But in these cases, and the cases therein cited, the grounds of the liability of the owner for injuries done by his vicious dog are very fully examined, and from them we deduce the above propositions.
*606There is usually an element of negligence in such cases; thus, the master of a vicious dog is ordinarily not liable to the person bitten, the dog not trespassing upon the latter’s premises, unless the master had notice of the vicious propensity of his dog. Of course the knowledge of the master is not an essential of the nuisance, but of his liability for it. It is not the usual habit of dogs to be vicious, especially in the presence of their masters, and notice is necessary in order to charge the master with the duty of suppressing or abating the nuisance, i. e., the dog. The burden of showing this notice is upon the plaintiff, and hence he must plead it ; the plaintiff has done so in the case before us. In May v. Burdett (9 Adol. & El. [N. S.] 101), cited in Earl v. Van Alstine (8 Barb. 630), the declaration alleged that the defendant wrongfully kept a monkey, well knowing that it was of a mischievous and ferocious nature and accustomed to bite mankind, and that the said monkey did bite the plaintiff’s wife, but the declaration did not aver that the defendant was guilty of negligence. The plaintiff had a verdict and a motion to set it aside was denied, partly because made after verdict, but the court also held that negligence was proved by proving the facts alleged.
Under our system of pleading the complaint is a statement of the facts constituting the cause of action. If proof of the facts alleged is proof of negligence, then the facts alleged constitute a sufficient charge of negligence.
We think the complaint sufficiently charges that the defendant knowingly maintained a nuisance by which the plaintiff was damnified. That so far as negligence of the defendant is an essential to his liability, it is implied in the statement of the complaint, and that it remains with the defendant to answer the charge.
