Five Samoyed puppies were allegedly stolen from their owner's backyard in Carlingford, early Wednesday last week.
Police said thieves entered the yard on Parkland Road and broke the padlock of the dogs' enclosure between 10pm on Tuesday and 7am the next day.
The five-week-old puppies, three males and two females, and their parents, Ricky and Lucky, were then taken.
However, the older dogs were later found.
"I got a call from an Epping vet who said there were two dogs there, microchipped in my name," said their owner, Richard Demarco.
"I'm very lucky to have Lucky and Ricky back — there were no injuries on them either. But they look really scared."
He said he first noticed something wrong on Wednesday morning.
"The dogs usually start barking around 7am but it was that time and there was no noise," Mr Demarco said.
"I looked in the backyard and saw nothing except the side gate was open."
He said he was still distressed about losing the puppies and wanted them back as soon as possible.
"It's very important because their mother is moaning every night which is sad and also disturbs the neighbours.
"The other thing is some other people have already paid for the puppies."
He said the dogs weren't microchipped yet but he believes if they are found he can prove ownership.
On Monday Mr Demarco told Hills News the puppies were still missing and he was still worried.
He appealed to anyone looking to buy Samoyed pups to carefully check any offered for sale.
