Okla. Stat. tit. 4, § 4-394

relating to impoundment and scientific research.

A. Except as otherwise provided by municipal ordinance, it

shall be the duty of the pound supervisor to deliver from among the

available impounded animals on the demand of an institution

possessing a license, such number of animals as the institution may

demand and be reasonably required effectively to carry on its

activities, subject to the following conditions:

1. Such animals shall have been impounded at least fifteen (15)

days for dogs without a license, and at least thirty (30) days for

dogs with license and remained unclaimed and unredeemed by their

owners or by any other person desiring the animal as a pet and

willing to pay applicable license fees and the reasonable expenses

incurred in the dog's detention; and

2. Any owner of an animal who voluntarily delivers the

possession of it to a public pound shall have a right to specify

that it shall not be used for scientific research, and if an owner

so specifies, it shall be the duty of the pound superintendent to

tag such animal properly and to make certain that such animal is not

delivered to an institution for scientific purposes; and

3. If a demand is made on a pound supervisor for a greater

number of dogs than he has available for release to the institution,

the supervisor shall withhold thereafter from execution all

unclaimed and unredeemed dogs until the demand has been met; and

4. Any animal in the pound to which an identification tag is

attached may not be disposed of until the owner has been notified.

B. Any city may adopt an ordinance setting the number of days

an animal must be impounded and setting restrictions or prohibitions

on the delivery of animals for scientific research.
