Can ivory satin/silk fabric dress shoes be repaired from being chewed up by a dog? - dress up shoes

I have bought recently, precious ivory dress shoes in a shiny fabric. Dog of a friend went to one of them. The most damage is the back of a heel. If I do not comply with any fabric to fit the structure of the article and again. Someone said that if the repair of footwear, leather, but otherwise could be fixed, nobody can fix it. Suggestions?
