Missing dog, Perth (WA)

Hi there my name is Blaize teoh, I’m posting for help about my mastiff puppy , his name is GHOST, he went missing early hours on Monday 1 st may , someone has jumped the neighbours fence and stole him 😡 I am deeply upset and appalled of this doing .. Me and the partner are so upset , lacking of sleep , stress and and jus depressed in general ? I was in hospital while it happened ? And the partner Kyla Rourke left him outside late at night so he can go to the toilet .Next thing some boof head has jumped the fence and stolen him ? I got a call the next morning first thing ? We are lost , and are asking for any help or information ? We have tried Facebook pages,pounds , shelters we have him microchipped , Kyla made police report It’s not fair it’s nearly been a whole week 🥺I am offering a reward coz no amount of money can buy happiness and our family member back of 1000 hope and prayer he is safe and well
