Nasty Critter! Dog Conditioner - Deep Clean & Detangle (1 Gal)

In this review of NASTY CRITTER! dog conditioner the bottom line is simple: it is best for owners and professional groomers who want a reliable, economical deep cleaning and detangling conditioner for pets 8 weeks and older. The reviewer found the formula effective at moisturizing and revitalizing dull coats while loosening tough mats and tangles, and appreciated that it can be used as a leave-in between baths. The product is framed as a practical grooming staple rather than a luxury treatment, and its dilution ratio makes the gallon size especially useful for frequent use.

Key Features

• Trusted professional formula: Used by Girl With The Dogs, this conditioner provides a groomer-grade balance of cleansing and conditioning for routine salon work or home grooming.
• Moisturize and revitalize: The formula restores sheen and helps alleviate dry, flaky skin when used as part of a regular care routine.
• Loosens mats and tangles: Lightweight detangling action reduces brushing time and makes removing stubborn mats easier without weighing the coat down.
• Static-free silky softness: The additive-free application minimizes static and leaves fur feeling soft and manageable after rinse or leave-in use.
• Versatile leave-in use: Can be diluted for rinse or applied sparingly as a leave-in refresher between baths for ongoing coat maintenance.
• Economical dilution: Mix 16 parts water to 1 part conditioner to stretch the gallon for multiple grooming sessions while maintaining effectiveness.

Who It's For

NASTY CRITTER! suits pet owners who regularly bathe medium to large dogs, breeders, and professional groomers who need a cost-effective, multi-use conditioner that performs in both rinse and leave-in roles. It is particularly useful for breeds that mat or develop static, such as long-coated retrievers and poodles, and for households that want a single product for both dogs and cats aged 8 weeks and up.

Owners seeking a scented salon fragrance or a highly foaming lather may prefer alternatives, as customer feedback shows mixed notes on lather while praising cleanliness and softness. If a medicated or specialized skin treatment is required for severe dermatological conditions, a veterinary product should be chosen instead.
