I purchased this for emergencies, but it has been stored unused. It's 91cm wide, so it's large enough for big dogs. I think it would comfortably fit two small dogs. It can be used both indoors and outdoors. I think it can also be used for outings. It is compatible with seatbelts. It folds up small, so it doesn't take up much storage space. It is unopened, so please check the photos for the overall condition. Please understand that this is based on a personal opinion and storage condition. #PetSupplies #LargeDog #SmallDog #ForEmergencies #ForCamping #ForTravel #Foldable #Outing
