WIBTA if I stole/rescued my neighbors dog?

NTA, when I was a kid I lived on a farm with some livestock farms around the area. My dad who is a major animal disliker but this one summer a GR dog kept appearing for weeks at the farm and eventually he just started sticking around. He’d wait outside all night for us to come out and he would just be happy and excited. He was dirty, starving and had no collar or markings or anything so we kept him for a couple of months and slowly my dad got attached to him. By the 4th month the dog was pretty much family and my dad grew pretty attached, the dog was super sweet and basically was just glued to the hip of my dad and was just a big baby. Eventually someone convinced dad to find the owners who turned out to be like 20 acres away. We brought the dog back to the owners farm and I remember being so horrified at the conditions since it was basically just a big junkyard. My dad returned the dog and then found out about a week later that the original owners had the dog “put down” for wandering. I might be a little bias when I say take the dog.
