Senate approves livestock amendments that classify guardian dogs as livestock while with herds and raises penalties for livestock destruction

Senators debated House Bill 166 across an extended exchange before approving the measure on the floor by a roll-call of 21 yeas, 6 nays and 2 absent (SEG 1579–1633). The sponsor described two primary components: prohibiting issuance of certain wildlife permits to those prosecuted for livestock destruction and treating guardian dogs that live with and guard livestock as livestock for statutory purposes while they remain with the herd (SEG 953–981).

Floor questioning focused on practical and legal implications. Senators asked how a guardian dog’s status would change if it left the herd or entered private property, how the statute operates on open-range and public lands (BLM), whether the bill could inadvertently criminalize hunters defending themselves, and whether the bill’s new dollar thresholds for felony classifications (discussed as over $1,500 in the floor exchange) aligned with other property statutes (SEG 998–1316, 1390–1430). The sponsor and other supporters said that once a guardian dog breaches the herd perimeter and enters another person’s property it would be treated as a stray or aggressive dog, losing statutory livestock protections; the sponsor also agreed to work with the House sponsor to clarify the relevant statutory language (SEG 1079–1090; SEG 1520–1572).

Senator Winterton and several supporters emphasized recurring losses of livestock to misidentification or unlawful shootings and argued for stronger penalties to deter those acts (SEG 1326–1336). Opponents on the floor asked the sponsor to clarify precise statutory language and the scope of application, and several senators said they would support the bill only if the definitions were tightened before final enactment (SEG 1456–1516). The Senate passed HB166 and the sponsor committed to follow up on definitions and comparative penalty thresholds with the House sponsor.
