Criminal Penalties for Owners of Dangerous Dogs

Dog owners could face fines or jail time for violating legal restrictions on keeping dangerous dogs. They may also be charged with serious crimes if their animals attack and severely injure people.

It's every dog owner's nightmare: Your pet mauls someone, seriously hurting or even killing them. Although dog bites are fairly common, they rarely result in severe injuries or death. When they do, there's generally evidence that the owner failed to take precautions despite knowing that the animal presented a grave danger—usually because it was trained to fight or had already attacked or menaced people. In situations like that, dog owners will probably be liable to the injured people in civil lawsuits. They may also face criminal charges, under laws aimed at dangerous dogs or general criminal statutes.

Penalties Under Dangerous Dog Laws

At least 39 states have "dangerous-dog laws" laws that are intended to protect the public from dogs that are dangerous or vicious. In order to save the animals from being euthanized, owners must generally meet certain conditions, ranging from keeping the dog confined or muzzled to buying liability insurance or a special license. In many states, it's a crime to violate these restrictions, particularly if the dog hurts someone. Penalties range from fines to prison time for a felony. For example:

  • In Michigan, if a dog that's been declared dangerous is found at large or injures someone, the owner will be guilty of a misdemeanor. However, it will be a felony, if the injury is serious, or involuntary manslaughter, if the dog kills someone. (Mich. Comp. Laws § 287.321.)
  • Illinois makes it a misdemeanor to violate any restriction in the dangerous-dog law. If the dog hasn't been kept in an enclosure and seriously injures someone, the owner will be guilty of a felony. (510 Ill. Comp. Stat. § 5/26.)

Even when dogs haven't been declared dangerous, their owners may face criminal charges if their animals attack someone. In Washington, for instance, if a dog aggressively attacks someone and causes serious injury or death, the prosecutor can charge the owner with a felony. (Wash. Rev. Code § 16.08.100(3).)

And while it's unusual, some local laws subject owners to criminal penalties when their dogs bite or injure. An appellate court in Nebraska upheld a conviction for violating an Omaha ordinance against harboring a dangerous dog, after the defendant's dog seriously injured a guest in his house. The court held that the ordinance didn't violate the owner's constitutional due process rights, even though it didn't require that the owner knew about the animal's dangerous tendencies. (State v. Ruisi, 616 N.W.2d 19 (Neb. Ct. App. 2000).) Similarly, an appellate court in Kansas upheld the conviction of a woman in Topeka for violating a city ordinance making it a crime to permit a dog to attack someone. The animal had rushed from the woman's garage and bitten a mail carrier. (City of Topeka v. Mayer, 826 P.2d 527 (1992).)

Dogs as Dangerous Weapons

When there's evidence that a dog owner gave a command or encouraged the animal to attack someone, courts may find the owner guilty of using the dog as a dangerous weapon to commit a crime like assault. Some examples:

  • In an Indiana case, a dog owner let her pit bull out of the house and said things like "Get'er," "Sic," and "Kill that b*tch," as the animal attacked a relative who had come by to drop off some medication. The appellate court upheld her conviction for using the dog as a dangerous weapon to commit aggravated battery. (Gilbert v. State, 874 N.E.2d 1015 (Ind. Ct. App. 2007).)
  • Similarly, a Georgia man ordered his dog to sic and bite a police officer who was trying to arrest him, and the dog attacked. The Georgia appeals court found there was plenty of evidence to support the dog owner's conviction for aggravated assault on a peace officer with a deadly weapon. (Braziel v. State, 739 S.E.2d 13 (Ga. Ct. App. 2013).)
  • After a landlord confronted a strange man with a dog in her apartment building, she heard the man say something "stern" to the dog and saw him release or unravel the leash. The dog immediately lunged and bit her. The appeals court found enough evidence existed to support the man's conviction for assault and battery with a dangerous weapon. The state didn't have to prove that the dog had been trained to attack or what the owner specifically said to the animal. (Commonwealth v. Fettes, 835 N.E.2d 639 (Mass. Ct. App. 2005).)

Negligent Homicide or Murder With a Dog?

In extreme cases, an owner may be charged with negligent homicide when a dog kills someone because the owner's failure to control the animal was reckless or criminally negligent. In Louisiana, the negligent homicide law states this explicitly (La. Rev. Stat. § 14:32.)

In a California case that made headlines at the time, a woman was initially convicted of negligent homicide and second-degree murder after her huge Presa Canario dogs attacked and killed a woman in the hallway of their apartment building. Evidence showed that the dogs had a history of threatening people and that the owner had trouble controlling them. The California Supreme Court overturned the murder conviction (because it required proof that the owner had acted with a conscious disregard of danger to human life), but she didn't appeal her conviction for negligent homicide. (People v. Knoller, 158 P.3d 731 (Cal. 2007).)

In another second-degree murder case, the Kansas Supreme Court found that the state didn't have to prove that a dog owner knew her Rottweilers would attack and kill a child, only that she acted recklessly in a way that showed her extreme indifference to the value of human life. The evidence showed that the dogs had a history of menacing behavior, that the woman had "fostered" their aggressiveness by failing to train them properly, and that she had ignored the predictable consequences. (State v. Davidson, 987 P.2d 335 (Kan. 1999).)
