NATASHA Smith knows the value of her Dogue de Bordeaux dogs, so she keeps her property secure and is hesitant to advertise her address.
However, one of her greatest fears came true on Thursday, when puppy Orange was stolen through no fault of her own.
The 10 week-old Dogue de Bordeaux, or French Mastiff, was snatched in a bizarre incident from a Redbank Plains vet clinic.
Ms Smith said Orange had been receiving treatment for a suspected virus when someone broke into one of Greencross Vets' outdoor runs and grabbed the pup.
"She was very sick and had been at the clinic for a while. She wasn't in good shape," she said.
"Her snatching could've been a silly act, or it could've been calculated with a plan in place for her - either way, it's a decision that's put her life at risk.
"I've spent seven years breeding and showing these dogs and this is a huge shock; I feel terrible."
Ms Smith said the puppy needed to continue her treatment.
She urged the person who stole Orange to return her.
"The Dogue de Bordeaux might be a valuable breed, but a sick puppy with a life-threatening illness is of no value to anybody," she said.
"She's also just been desexed; she has no breeding value.
"I hope whoever took her realises it was a mistake - if they have a heart they should give her to a pet shelter, a pound or a vet. I just want her home safe."
Greencross Vets Redbank Plains' Jacque Pollitt said her team were also concerned for the puppy's safety.
"Our primary concern is for the puppy's well-being and safe return," Ms Pollitt said.
"(She) requires urgent and ongoing veterinary care."
