I have been ordering the Trachea (and pizzles) now for months and my 2 miniature Dachshunds love them, my German Shepherd puppy (10 weeks old) has also started having cut offs of Trachea and it is the only thing I can give her to stop her following me everywhere. Really good size and we split a full large Trachea down into about 4 or 5 cut offs. No impact or effect on my dogs faeces/stomachs. A very happy man with 3 very happy dogs.
