apply to veterinary clinics or hospitals, government-run animal shelters, nonprofit rescue centers or people who sell animals from family-owned litters.

The board voted 4-3 to adopt the new rules.

Trustees Dawn Abernathy, Holly Kim and Ray Semple were for the plan, while trustees Holly Kim, Dakotah Norton and Kerston Russell were against it. Mayor Steve Lentz broke the tie.

The vote followed comments from more than a dozen audience members on both sides of the issue.

“We don’t want to support businesses that support cruelty,” said Mundelein resident Claire O’Dea, who favored stricter rules than what were adopted.

Conversely, former trustee and veterinarian Ed Sullivan said most breeders sell healthy puppies and called the ordinance “an effective compromise.”

Norton said a local ban on the sale of pets from large-scale breeders would have been a “small step” toward the better treatment of animals.

Abernathy said puppy mills are a federal issue because the animals often cross state lines. She urged the activists in the audience to pursue congressional legislation.

A local ban, Abernathy said, “isn’t going to solve your problem.”
