A dachshund named "Obie" has lost an astounding 50 pounds after more than a year of dieting, a tummy tuck procedure and many long walks.

Obie used to weigh 77 pounds, but is now at a normal weight of 27 pounds.

The 5-year-old pooch and his owner, Nora Vanatta, live in Portland, Ore.

The dachshund has a website that tracks his weight loss and his own Facebook page where Vanatta has posted several pictures (below).

Obie went viral on the web last year when pictures of his huge belly, dragging on the ground, were posted on social media sites, reports the Daily Mail.

According to The Huffington Post, the dog used to belong to an elderly couple that overfed him and gave the canine little exercise. Thankfully, Vanatta adopted Obie and put him on a training schedule to lose weight.

However, Oregon Dachshund Rescue owner Jenell Rangan has accused Vanatta of exploiting Obie on TV shows and the web for "sensationalistic promotional value."

Vanatta did set up a Paypal page for people to donate money to pay for Obie's care and collected thousands of dollars, but insists the money is spent for the dog's benefit.

"I feel tremendously blessed to be involved in his rehabilitation and I am amazed at the outpouring of love and support that I have received," Vanatta wrote on Obie's website. "My hope is that he can be an inspiration to any person or animal trying to lose weight. It is so important to introduce pups and kids to a healthy lifestyle and food choices as early as possible."
