28 pups have been recovered from a pick up truck on a roadside near Larne Port.
The Cockapoos and Cocker Spaniel pups were taken into council’s care after PSNI stopped the vehicle following a tip-off by a member of the public.
They will now be looked at by vets and rehomed with the assistance of local charities.
The dogs have been distributed to a number of local charities for rehoming – Mid Antrim Sanctuary, USPCA, Almost Home, Cavaliers in Need, Chance of a Lifetime.
The Larne discovery comes just weeks after another operation rescued 17 pups in time for Christmas.
Council has also been working with DAERA in recent weeks to detect more illegal movement of dogs at ports across Northern Ireland.
Mrs Patricia Allen, head of council’s Public Protection, Health and Wellbeing said: “We’ve been working closely with statutory organisations in recent months and it’s great to see that with this level of collaboration, almost 40 pups have been recovered.
“A special thanks goes to the member of the public who called in. Without their help we don’t know what would have happened to these dogs.”
