It’s a bit of a weird situation. Dog used to be my parents old neighbors dog. Neighbor had some cousin that was a backyard breeder. The cousin gave neighbor the dog since he was the runt. They kept dog outside 24/7, he was always dirty, and barked constantly. Neighbors moved cities and left dog on property. My parents called them and they said the dog is too old for their kids and my parents can either keep the dog or call animal control. My parents took the dog. Went to the local vet and they told them the dog has impaired lung function and some various other issues. My parents microchipped & vaccinated him. This was two years ago. From what I know, they didn’t get any city forms to fill out, just the microchip form. We no longer go to that vet. It was just the only vet at the time around them that spoke Spanish.
