On an invalid's benefit, she is unable to raise the $1000 needed for a dog wheelchair.
"He's slowly losing power in his back legs. Eventually his legs will go," she said.
Bear, who is thought to be between 10 and 13 years old, was taken in by Ms Miller after he was found wandering with a matted coat and overgrown claws.
It took two weeks of grooming to return him to his former glory.
"He came fully trained. He's had a good life and something went wrong," she said.
Well known around the neighbourhood, Bear, who wears leather boots to protect his sensitive feet, is taken on a daily walk to Kulim Park.
"He loves kids and everybody and he likes cats," Ms Miller said.
He has also accompanied Ms Miller when she has collected for various charities.
"On Christmas Day he usually goes to the park in a Santa hat," she said.
She hopes that with a wheelchair the pair can continue their walks and their lives together.
"If his legs eventually go on him that's it."
