We have a nine month old puppy (Catahoula/Mastiff mix) who for the most part is fairly well behaved. However lately she has started chewing on blankets... nothing else just blankets (well blankets/sheets/comforters). She has now chewed up a sheet and our comforter. She doesn't chew the stuffing at all (*knock on wood*) so it is basically all the same fabric, so I don't know if that could have something to do with it? It is at night when she is in our room, she has toys in there as well so it isn't just that she is bored (I don't think anyway??). Does anyone have any advice??
