The former Auckland taxi driver said when the SPCA closes he will have no reason to get up in the mornings again.
He has, over the past three years, walked 82 different dogs. One dog he had taken on 140 walks and two dogs had been on 70.
The dedicated volunteer was going to miss meeting the people he had become familiar with over the past few years, after establishing a route "up and down" High St.
"I get people going past in cars tooting and waving at me, I don't even know who they are, but it's easier just to smile and wave."
He said walking the dogs on the High St was was an opportunity for people to see the dogs, which he hoped would lead to the animals being adopted.
Mr Anderson said besides all the ruckus going on at SPCA Wairarapa over the past two years, the centre had seen a lot of good people coming through.
"I want to see SPCA Wairarapa open again as soon as possible."
Mr Anderson's wife and carer, Kay, said the dog-walking gives her husband a purpose in life. "And it helps me because he's in a good mood because he's gone out and walked his dogs."
She anticipates "a period of depression just beyond the horizon if we can't get the SPCA to stay open".
Mrs Anderson said the SPCA was good for people with disabilities, who sometimes related better to animals than people.
She said the SPCA also helps people struggling financially to have their pets de-sexed.
She said Wairarapa was a big area and they needed the SPCA to stay open.
The couple said 200 businesses donating $100 a month would keep the SPCA going.
"I'm sure there's people out there who can help," she added.
