"Most of the dogs go to homes out of the district. Some go as far as the South Island. I sent a wirehaired German pointer to Picton recently."
She also uses her contacts in the animal welfare movement, such as the Tokoroa Animal Rescue, taking up to eight dogs at a time.
Others go to people who adopted dogs from the Bay of Islands SPCA when she managed its kennels for 13 years.
"A lot of people remember me. When their dog passes away, they contact me to see what I've got."
Council field services operations manager Andrew Dowdle said shifting the pound from Kaikohe to Ms Dennis' place in 2008 was a good move.
"The facility at council headquarters had become unsuitable. It was too small and the sound of dogs barking bothered neighbours and council staff."
The council was delighted to have secured her services and impressed with the results she had achieved on its behalf.
"Her knowledge of dogs and their nature is second-to-none. She'll only ever home the right dog to the right home."
Auckland construction company owner Ben Price is thrilled with the beardie-collie-huntaway cross female he adopted a month ago after seeing an ad on Trade Me.
Mr Price said he had been looking for a dog for months but was disappointed with the selection at the SPCA's Mangere dog pound. Many had been ill-treated or were staffie or pitbull crosses.
He was happy to drive 250km to collect the dog, which is now a much-loved member of his family.
"You're going to have it for at least 12 years, so you want to be able to meet it and see what it's like. A three-hour drive is well worth it."
