Loulou has new knees thanks to the generosity of Hamilton News readers.
Hamilton News reported last month that Paws 4 Life founder Rachael Maher was trying to raise money for Loulou and another dog to have surgery on their knees.
The dogs were rescued from a puppy mill north of Hamilton.
Loulou, a little brown poodle, had surgery on one knee last week and was speyed at the same time.
She will have her second knee operated on soon.
Rachael said people had donated about $1000 since the story appeared in Hamilton News.
Non-profit organisation Paws 4 Life takes in unwanted, abused and neglected animals and took possession of 20 dogs in August from a puppy mill operating north of Hamilton. None of the dogs was registered or microchipped.
Two of the dogs were so sick they had to be euthanased.
Rachael said all the dogs were in "shocking condition". Most of the remaining 18 had severe dental issues and as such had to have the teeth they had left removed.
Rachael said the dogs that were rescued from the puppy mill were not socialised, were terrified of men and didn't know how to behave around children.
However, they have been rehabilitated and all 18 have been rehomed.
