"If you have him, please make sure he is warm at night and he LOVES his food, and like to have cuddles, I really want him back, no questions asked, even bring him back anonymously and say you found him."
McNeilly adopted the Dalmatian-staffy cross from the SPCA 12 months ago.
Buster had been left on a five-metre lead in the backyard of McNeilly's Ohaupo home on Friday while he went to the gym.
When he arrived home around 4.40pm, Buster was nowhere to be seen.
He realised Buster hadn't just slipped off his lead and escaped because his collar was gone and the lead was still intact.
There had been one reported sighting of a dog like Buster with a group of teenagers around 5pm near Tomlin and Ohaupo Rd. Police were following the sighting up.
Anyone who has seen Buster is asked to call the Hamilton Police Station on 07 858 6200.
