Missing Maltese x Shih Tzu Dog: Help Find Kobe!

My Maltese x Shih tzu male dog went missing at around 11 am on 9th July 2023 in Coolaroo 3048. He has white fur and he is chubby for a small dog. He went missing along with our 2 other dogs from our backyard, and how they manage to get out is still in question. One of our dogs was founded by a good samaritan at a progress reserve park in Coolaroo at 11:30 am, while the other dog was picked up at Craigieburn Road at Craigieburn at around 11:30 am-12 pm. While Kobe remains missing, I, unfortunately, do not have proof that Kobe was stolen from our house. But it is weird how we manage to find the other two dogs in different locations while Kobe still remains missing. Our family and relevant parties are still investigating how this happened and so far we have no leads. Kobe is microchipped and not desexed. We are offering a reward ($$$$) to someone who can give out information or just return him to us, no questions asked. Please share and keep an eye out.
