I can remember when at my MIL house my Heidi got to one of the other dogs food and totally pigged out on it! she would swallow it as quickly as she could before i could get to her! even after just having her own meal!

  I noticed that she had blown up..she literally could hardly walk her tummy was soooo tight!

 i didn't know what to do...she ended up throwing alot of it back up..and she went to the toilet the next day too and i hardly fed her the following day to give her tummy a rest! she was such a piggy i had to watch her like a hawk if the other dogs were being fed.
