Ohio dog law for people who want a protection dog
Two sections of Ohio Revised Code do most of the work. Read them yourself and then ask an Ohio attorney about your situation.

Confine it and control it
Ohio Revised Code 955.22 requires an owner to keep a dog physically confined or restrained on the premises, using a leash, tether, adequate fence, supervision or secure enclosure, and to keep it under the reasonable control of some person.
For anyone buying a dog with protection training, that wording is the baseline. A dog that gets over a low fence or slips a gate is your legal problem as much as a practical one.
Nuisance, dangerous and vicious
The same section sets different consequences for nuisance, dangerous and vicious dog acts, and the penalties rise with the label. Negligently failing to prevent a vicious dog from injuring or killing a person can be a felony, according to the statute text.
The statute also lets a court order destruction of a dog after certain acts. Read the full section before assuming that a protection title shields you.
If a dog is declared dangerous
The statute lists extra duties for a dangerous dog owner, including locked, covered confinement on the property, a short leash or tether away from home, and notice to the dog warden if the dog gets loose. See Ohio Revised Code 955.22 for the exact list and any updates.
Civil liability for bites and damage
Ohio Revised Code 955.28 makes the owner, keeper or harborer liable in damages for injury, death or loss caused by a dog. It lists situations where liability does not apply, such as a person committing a criminal trespass or tormenting the dog on the owner's property.
That is liability without a requirement to prove carelessness on your part. It is one reason the checklist insists on seeing the dog under control.
County licenses and the dog warden
The Union County dog registration FAQ says all dogs older than three months must be licensed and should wear a valid tag indoors or out. It describes a yearly renewal window from December 1 to January 31, a late penalty, and a prompt-purchase rule for people moving in from another state. Other counties publish their own forms and fees, so use it as an example and look up your own auditor.
A rabies tag is a separate item from the license. Keep both current. If a dog is designated dangerous, the statute above also tells the owner to notify the local dog warden when it gets loose, so learn your warden's number early.
