Duckie gives dilution lines but I ignore those and do what the bottle says (1 part shampoo to 8 parts water and 1 part conditioner to 16 parts water) although I do do the conditioner a tad strongerhttps://www.amazon.com/Coat-Handler-Undercoat-deShedding-Conditioner/dp/B0B5VYGX2G
Don’t skip the conditioner!!! It’s important! Also don’t skip duckie! Without it is more expensive because it doesn’t dilute as well
