Long-haired dogs bring serious shedding drama into your home. The constant battle against tumbleweeds of fur and matted tangles makes bath time a strategic event rather than a simple chore. A shampoo formulated specifically for long coats targets the undercoat without stripping the protective topcoat, reducing loose hair at the source while keeping strands silky and knot-free.
I’m Mohammad Maruf — the founder and writer behind WellFizz. I’ve logged hundreds of hours studying grooming chemistry, reading through customer experiences across coat types, and cross-referencing formulations to find what actually controls shedding.
If you own a double-coated breed, a silk-coated pooch, or any pup whose fur seems to multiply, you need the right bottle. This guide breaks down the five best contenders to help you find the best dog shampoo for long hair that matches your dog’s specific coat needs and your grooming routine.
How To Choose The Best Dog Shampoo For Long Hair
Not all dog shampoos treat a flowing coat the same way. Long hair requires a specific balance: enough cleansing power to reach the undercoat and remove trapped dander, plus enough conditioning to prevent the outer coat from turning into a matted mess. Look for formulas that use natural oils to loosen dead fur rather than harsh detergents that strip natural moisture.
Omega Fatty Acids vs. Harsh Surfactants
A quality deshedding shampoo for long hair relies on Omega-3 and Omega-6 fatty acids to strengthen hair follicles at the root. This reduces shedding from the inside out. Avoid formulas heavy on sulfates—they create big lather but leave long coats brittle and prone to breakage.
Concentration and Dilution Ratios
Concentrated shampoos give you control over how much cleaning power you apply. A 32:1 or 16:1 dilution ratio allows you to customize the wash for your dog’s coat thickness. Ultra-concentrated options stretch further per ounce, which matters when you’re bathing a large breed with a full double coat.
Conditioning Agents and Detangling Help
Long hair tangles easily during a bath if the formula leaves strands dry. Look for added conditioners like panthenol (Vitamin B5), aloe vera, or shea butter. These ingredients smooth the hair shaft, making post-bath brushing far easier and reducing the risk of painful mats.

In‑Depth Reviews
1. Earth Rated Deshedding Dog Shampoo
Earth Rated earns the top spot thanks to its smart 3-in-1 formula that cleans, conditions, and deodorizes in a single step. The jojoba oil component actively loosens dead undercoat during the wash, making it particularly effective for double-coated breeds like German Shepherds, Huskies, and Corgis. The precision nozzle design is a thoughtful touch—it applies product directly under dense fur, reaching the skin where shedding starts.
The ingredient profile stands out as hypoallergenic and free from alcohol, parabens, and sulfates, making this a safe choice for dogs with skin allergies. Customers report that their dogs stopped itching and scratching after switching to this wash. The White Tea and Basil scent is mild and fades quickly after rinsing, which owners of scent-sensitive dogs will appreciate.
One minor complaint involves product separation after extended storage—the formula can harden if not shaken thoroughly before each use. But for a mid-range option that delivers groomer-quality results without irritation, this is the most balanced pick for long-haired dogs.
Why it’s great
- Hypoallergenic and gentle enough for daily use on sensitive skin
- Jojoba oil penetrates the undercoat to loosen dead fur
- Precision nozzle reaches skin under thick, long hair
Good to know
- Formula may separate over time and requires vigorous shaking
- Scent is very light—not ideal if you want strong fragrance
2. The Coat Handler Undercoat Control deShedding Shampoo
The Coat Handler is a professional-grade, ultra-concentrated formula that requires a 32:1 water-to-shampoo ratio. This dilution means one 16 oz bottle yields over 4 gallons of usable wash, making it one of the most economical options for owners of large, heavy-shedding breeds. The Omega-3 and Omega-6 fatty acid blend strengthens hair follicles at the root, which customers report dramatically reduces shedding after just two baths.
Real owners of Akitas, Australian Shepherds, Border Collies, and German Shepherds confirm that this shampoo loosens the undercoat enough to brush out huge clumps of dead fur. The coconut scent is pleasant without being overpowering. It also works well on cats, which is a nice bonus for multi-pet households.
The formula is soap-free, biodegradable, and won’t wash off topical flea and tick treatments when used as directed. However, because it’s so concentrated, you need to be precise with dilution—using it at full strength can be wasteful and harder to rinse from thick, long coats.
Why it’s great
- 32:1 concentration provides excellent value per wash
- Omega fatty acids strengthen hair follicles to reduce shedding long-term
- Safe for use on cats and won’t strip topical flea treatments
Good to know
- Requires careful dilution—using full strength is inefficient
- Coconut scent may not appeal to all owners
3. We Love Doodles Deshedding Shampoo
This eco-friendly option from We Love Doodles is crafted without parabens, sulfates, formaldehyde, alcohol, or synthetic dyes, making it a top contender for dogs with allergies and sensitive skin. The gel-like thickness prevents the shampoo from running all over the place during application, which is especially helpful when washing a long-haired dog that twists and turns.
Owners of white-coated breeds like Bichons, Maltese, and Bolognese report that this shampoo restores bright white fur and leaves it soft and shiny. The formula effectively controls dander and neutralizes “dog smell” between baths without leaving heavy residue that tangles long hair. It’s also safe for cats and small animals.
The lack of strong fragrance is a double-edged sword—it’s great for dogs with respiratory sensitivities, but if you want a noticeable scent that lingers, this isn’t it. Some users noted that multiple washes were needed to fully whiten stained white fur.
Why it’s great
- Gel-like consistency stays put during messy baths
- Brightens white coats without harsh bleach
- Free from common irritants—safe for allergy-prone dogs
Good to know
- Very mild scent—may not satisfy owners who prefer fragrance
- Requires multiple applications for deep whitening
4. Nature’s Specialties EZ Out Ultra Concentrated Deshedding Shampoo
Nature’s Specialties EZ Out is the choice of professional groomers for a reason—one 16 oz bottle dilutes to up to 2 gallons of usable shampoo. The proprietary mild shampoo base is pH-balanced and includes aloe vera, conditioning panthenol, and Vitamins A, D, and E. The formula is non-toxic and biodegradable, so it’s environmentally responsible for frequent grooming.
Real-world reports confirm that this shampoo pulls out the undercoat in clumps, making it ideal for heavy shedders like Huskies and Golden Retrievers. A pro tip from users: apply the shampoo, let it sit for a few minutes before rinsing, and brush the undercoat while the conditioner is still in to maximize hair removal. The rosemary scent is pleasant and can last over a week on the coat.
The biggest caution is that a small number of dogs have had allergic reactions to this formula, including blisters and sores. Always perform a spot test before the first full bath. The ultra-concentration also means you should only dilute what you plan to use immediately—pre-diluted batches may lose efficacy.
Why it’s great
- Ultra-concentrated formulation yields up to 2 gallons per bottle
- Aloe vera and panthenol condition long hair without residue
- Rosemary scent lasts over a week on the coat
Good to know
- Spot testing required—some dogs may develop allergic reactions
- Must be diluted fresh each bath; pre-diluted batches may separate
5. Hempz Petz 2-in-1 Dog Shampoo & Conditioner
Hempz Petz combines shampoo and conditioner into a single bottle, cutting down bath time for owners of wiggly, long-haired dogs who hate long wash sessions. The citrus and raspberry scent is fresh and summery, and customers consistently praise how the smell lingers on the coat between baths. The hemp seed oil and shea butter base moisturizes the skin while cleaning, reducing dryness and itchiness.
The 2-in-1 formula lathers thickly and rinses clean without leaving behind sticky residue that can trap dirt or cause tangles in long hair. Owners of Poodles and other curly-coated breeds report softer, more manageable coats after switching. The 17 oz flip-top bottle is larger than standard shampoo bottles, offering good value for the price point.
The formula is vegan, gluten-free, and paraben-free, but the scent strength may be too intense for dogs with very sensitive noses or owners who prefer unscented products. For a quick, effective wash that conditions and deodorizes in one step, this is a solid budget-friendly choice.
Why it’s great
- 2-in-1 shampoo and conditioner saves bath time
- Hemp seed oil and shea butter moisturize without greasiness
- Pleasant citrus-raspberry scent that lasts between baths
Good to know
- Strong scent may be overwhelming for sensitive dogs
- Not concentrated—bottle may be used up faster than concentrates
