Some dogs' skin reacts to more or less any shampoo going, which is part of why a growing number of grooming products lean on prebiotic and postbiotic ingredients rather than fragrance to do the work.

This one contains Inulin as a prebiotic alongside a Bifida/Lactococcus/Lactobacillus Ferment Lysate as a pro- and postbiotic blend, alongside oat kernel flour, linseed oil, pumpkin seed oil, aloe vera leaf juice powder and blueberry fruit extract. It's manufactured in the UK by Lakeland Cosmetics Ltd in Workington, Cumbria, and is for external use on dogs from 8 weeks old.

One thing worth knowing. Bugalugs don't publish how much to use, how long to leave it on, or how often to bathe with it — there's no dilution ratio or bathing frequency on the card, so use your usual bathing routine and go by how the dog's coat and skin respond. Discontinue use and see a vet if any irritation develops.

Who it's for: owners of dogs with reactive or sensitive skin who want a shampoo built around prebiotic and postbiotic ingredients rather than fragrance, suitable from 8 weeks old.
