many thanks for your reply. I did try cayenne pepper one day, and she licked it but just drank some water afterwards. I will try this again for longer, as I wasn't sure if it was harmful to her. She is on CSJ puppy champ food, which she loves, but eats so fast, and I just wanted to ask you what I could do to slow her down. Somebody online suggested putting large stones mixed with it, but I don't like the sound of that, as she eats small stones from the garden sometimes anyway, which we are trying to stop. Any ideas please?
