Please, kijiji is not the most effective way to rehome a loved dog.
Try contacting the Kitchener/Waterloo Humane Society and see if they have any foster homes or if there is any way they may be able to help Skipper. If they are unable to, ask them for a list of Rescues in and surrounding your area. Then ask your grandmother to be patient...that you're trying to do the responsible thing here.
