The financial penalty was made after a Kent Police investigation into two linked incidents near Maidstone last year, which led to the death of livestock.
The first incident happened on 22 October 2022 at a field close to Chart Hill Road, when three dogs chased and attacked several ewes which fell into a river and drowned. The dogs also mauled and seriously injured a number of other sheep. On 24 October, the dogs returned to the same location, where they killed another four sheep.
