The poor dog I can't believe your aunt and uncle can't see for themselves that she needs to go on a serious diet..

But yeah, I do understand where you're coming from when you just can't get it into their heads that dogs are NOT hungry just because they beg at the dinner table.
When I still lived with my dad he was constantly feeding Tiki table scraps and I don't know how many days I have spent not talking to him because I got so angry at him.

..But still.. This dog needs serious help. Please keep on trying to talk sense into them.
