A curly coat holds onto knots the way straight fur does not, so a shampoo aimed at that coat type is really being asked to do two jobs at once — clean, and leave the coat easier to brush through afterwards.

Animology's Curly Coat is enriched with oatmeal and shea butter alongside conditioners, and it's built to be diluted rather than used neat: at a 20:1 ratio, so the 5-litre bottle is meant to be mixed down into a much larger volume of usable shampoo rather than used neat. It's suitable for all coat and skin types, including sensitive skin, and for dogs from 6 weeks old.

• 5-litre concentrate, diluted at a 20:1 ratio
• Contains oatmeal, shea butter and conditioners, plus Pro-Vitamin B5
• Suitable for all coat and skin types, including sensitive skin
• For dogs from 6 weeks of age
• A mild, deep-cleaning action described as not stripping the coat's essential oils

On the size. This is a 5-litre trade-size bottle, not a small pump bottle for the bathroom shelf — it's diluted before use, so you'll need a container to mix it in and somewhere to store the rest. It's the better buy if you groom more than one dog, or one dog often; it's a lot of shampoo for a single occasional bath.

Who it's for: owners or groomers with a curly-coated dog — poodles, cockapoos and similar — who bathe often enough that a concentrate makes sense, and want something built for detangling rather than a generic all-coats shampoo.
