At one point, "Obie" the dachshund mix was up to 77 pounds. Now he's on a strict diet to get him back to a normal size of about 40 pounds.
Foster mom Nora Vanatta volunteered to take on the meaty dog after reading about him on a dachshund rescue Facebook page.
"I just read the story, and I was like, 'I'll take him, he can lose weight, how hard can it be?' I hadn't seen a picture or anything," said Vanatta.
Obie's foster mom says she gets letters and e-mails from people who watch the dog and have become inspired to lose weight too.
