Looking for my best friend (N/A)

I know this is a long shot but I’m looking for a dog I was forced to give up late 2023. To cut to the chase, I had to move back in with my parents and they always hated my dog. Always. While I was at work I came home to an empty dogbed. My sister said my mom called animal control and got him taken as a stray. I called every shelter i could in and out of Portland. No luck anywhere. I was, am still am extremely heartbroken and angry- I want my big baby back. I still have all his things, hoping I can find him. His name is Champ- or champchamp. I’m crying writing this out and I’m hoping someone knows something. Please help me find him
