I don't think there is such thing as a tough toy for Gracie. She destroys everything! I ordered an Octopus from Tuffie toys. It was rated a 10. She tore a hole in it within the first 15 minutes. I originally got this toy for her six month old little brother and she took it from him. Dyson doesn't destroy things like she does. Unbelievable! Are you Corgis this destructive? She wouldn't let Dyson near it. It is funny to watch them interact. She is definitely the bossy one! I guess it is a female thing. My husband said that she has "anger issues." Iol!
