Three-year-old Brutus is slowly getting used to his new leg.
The American bulldog is one of only a few dogs in Australia to get a prosthetic limb.
Made to measure by Belmont-based TLC Unlimbited, the leg has been crafted to the standards expected by the company's human patients.
Brutus was last month struck down with osteosarcoma, a cancerous bone tumour that forced his Ocean Keys vet to amputate his leg.
He was fitted with his prosthesis only yesterday but according to owner Honi Connell he's never looked happier with his tail wagging with each baby step.
"It's all happened so quickly," she said.
"It feels good, he's been so strong and I can tell he's really happy now."
Helke Miller, who made the prosthesis, said Brutus was taking to his new leg well.
"He kept it on longer than most children we fit," she said.
"They throw the limbs across the room or even at you at their first fitting."
Using pictures and information from US websites specialising in limbs for animals as a guide, TLC Unlimbited created its first animal prosthesis for Brutus in about two weeks.
"The socket has been specially designed for Brutus and the materials are the same that we would use for humans," Mrs Miller said.
She said there was a growing market for prosthetic limbs for animals.
It has been a hard road for Brutus.
He was saved from euthanasia about 18 months ago by Ms Connell, who is his fourth owner.
"He's such an adaptable dog, he's got a good spirit and he's lucky because I'd do anything for him," Ms Connell said.
The prosthesis cost $1500, with additional vet bills approaching $2800.
Ms Connell hopes to raise money to help pay for Brutus' limb.
Any additional funds collected will go to Saving Animals From Euthanasia.
