I thought our dog was a sheltie but just took her to the vet and at 1year and 4months she is 18 inches tall and roughly 38 lbs..very lean though the vet said. We rescued her and thought she was a sheltie and she has stopped growing but hasn't filled out yet of course..extemely hyper ..gallops the back yard like a "bat out of hell" so to speak and barks non stop outside. Could she still be a large sheltie? Can they get that tall? her head reminds of a fox and she is sable in color
