Okla. Stat. tit. 4, § 4-46: Muzzle and restraint of certain dogs required - Local

regulation of dangerous dogs - Dogs not to be declared dangerous.

A. It is unlawful for an owner of a dangerous dog to permit the

dog to be outside the proper enclosure as defined by Section 44 of

this title, unless the dog is muzzled and restrained by a

substantial chain or leash and remains under the physical restraint

of a responsible person over sixteen (16) years of age. The muzzle

shall be made in a manner that will not cause injury to the dog or

interfere with its vision or respiration but shall prevent it from

biting any person or animal.

B. Potentially dangerous or dangerous dogs may be regulated

through local, municipal and county authorities, provided the

regulations are not breed specific. Nothing in this act shall

prohibit such local governments from enforcing penalties for

violation of such local laws.

C. Dogs shall not be declared dangerous if the threat, injury,

or damage was sustained by a person who, at the time, was committing

a willful trespass or other tort upon the premises occupied by the

owner of the dog, or was tormenting, abusing, or assaulting the dog

or has, in the past, been observed or reported to have tormented,

abused, or assaulted the dog or was committing or attempting to

commit a crime.
