My old dog basically lived a half-life from my fat parents overfeeding him garbage from the table. His diet was basically chips, bacon rind, whipped cream, bread, crackers, the grisly bits of meat, lamb bones... And his health problems were countless: IBS, hernias, cushings, and ultimately cancer. Cost us thousands in vet bills and by the end he just wasn't a dog anymore. He was a dog shaped body stuffed with drugs to keep him alive.
