CET dental chews with hextra

[Sally, Echo and Emmi]

Hi! These were suggested to me to use with my doodle who now has his permanent teeth. Does anyone have anything positive or negative to say about these chews? I did a search, especially on the hextra part but most things out there seem to be put out there by the company. I would love some input before I attempt to give these to my precious pup!! Thanks so much!
