So, no answer yet on who the owner is/was, and without that, we can't have him neutered, vaccinated, or anything. Its frustrating to say the least.
On the other hand, our efforts ended well with placing "Oscar" into a loving foster home. This family was a dog family, but lost their beloved companion to aggressive Cancer last Christmas. So, now until we find a "forever home" for "Oscar", these great people will nurse him back to health for whoever eventually winds up with this great soul.
Its almost like "Oscar" knows he is in good hands now, too. While he didn't seem too enthusiastic when I picked him up at the Vet's, when we got to the foster family, he brightened right up. He started to act almost like a puppy, albeit one that is still severely malnourished and living in an adult dog's body
Here is a picture of Stephanie and Oscar at their first meeting. Doesn't it look like they've been together forever?
