The beagle was 90 pounds when his owners dumped him at the city pound. They didn't want him anymore because he'd gained so much weight. They also thought he was also "too old," even though the dog was only 7 or 8.
He stayed at the shelter in Van Nuys, California, for a month. If he'd stayed any longer, he probably would have been put down - an obese dog like him needs extra care and has a hard time getting adopted.
