Authorities have revealed the six-month-old French Bulldog is a therapy dog for an eight-year-old boy in New South Wales who has a medical condition.
Dominic Yule told 9News: "I loved her into my heart. Please give me my dog back."
The boy was given the dog, named Kamia, to help regulate his emotions and he's devastated that someone would steal a puppy.
Dominic's mum Monique added: "I was horrified and lost for words. The lock on the gate had been removed, then it came to the realisation that she had been taken.
"I can't afford another puppy like her. It breaks my heart to see his little face every day asking questions.
"If you can drop her back off in the backyard, nothing else will be said. It would be amazing."
New South Wales Police have released a statement saying the dog was last seen 'between the hours of 7.30pm Thursday 16 January 2020 and 7.00am Friday 17 January 2020'.
The statement adds: "The puppy is believed to have been stolen from a residence on Minerva Street, Kirrawee."
Therapy dogs do an amazing job helping people like Dominic live with his condition.
According to Assistance Dogs Australia, the animals can provide 'remarkable improvement across their social, verbal and cognitive skills, as well as the ability to learn routines and structures that aid development, communication and community interaction'.
The organisation adds: "One of the most rewarding elements of this kind of placement is the impact our dogs have on the entire family.
"Often siblings of children with disabilities undergo stress and isolation from other family members, but our very special dogs have a habit of bringing families back together - providing assistance for kids in need, but also companionship, improved sleep, peace of mind and stability for the entire household."
If you have any information on the whereabouts of Kamia, please contact Sutherland police on 9542 0899 or Crime Stoppers on 1800 333 000.
