Out of 204 Yorkshire terriers found in a squalid windowless 40ft (12m) garden shed in West Sussex a year ago, only two are still looking for a home.
Dermot and Lynn had escaped from the carrier boxes in the shed
The pair, Dermot and Lynn, are still traumatised, Celia Hammond, founder of the Celia Hammond Animal Trust, said.
The starving terriers and six dead dogs were found in small carrier boxes full of excrement after their owner died.
Dermot and Lynn had escaped from boxes and were running around in the dark when they were found, said Ms Hammond.
She said: "If there's a bang or a noise they freak out. They can't be anywhere where they'll see a car. We couldn't get a lead on them for ages.
"They can go on a lead now, but they need to go to someone who is very patient - an experienced dog owner."
Ms Hammond wants to find an owner in Sussex or Kent for Dermot and Lynn, who are now about two years old, so that her charity is nearby to help with any problems.
"They were feral, but they are definitely much better," she said.
"They had probably never been touched."
And she added: "We have got them as far as we can, but now they need a permanent home."
So far, Dermot and Lynn have not been allowed to roam across the charity's 12 acres (4.8 hectares) in case they never come back, and it would be better if their new owner had an enclosed garden, she said.
The Celia Hammond Animal Trust was one of several Sussex charities to help the animals - it took in 86 of the 204 terriers.
Many had skin infections and disabilities, but are now healthy, happy and settled.
