Chris Christensen Big G vs FURminator (2026): Which Brush?

The Chris Christensen Big G and FURminator Undercoat deShedding Tool are different kinds of dog grooming tools: one is a long-pin slicker brush, and the other is an undercoat-removal tool. Both can collect loose hair, but their main jobs—and the coats they suit—are not the same.

This Chris Christensen Big G vs FURminator comparison addresses tangles, shedding, and coat safety. The reviewed product is Big G Medium; the comparison model is FURminator Large Dog Long Hair.

Verified Specifications & Buyer Implications

These specifications come from the manufacturers’ published information. The FURminator details below refer specifically to the Large Dog Long Hair undercoat tool, not every product carrying that brand name.

Design, Build & Setup

The Big G uses a cushioned bed of closely spaced bent pins rather than a single metal grooming edge. Chris Christensen states that the Big G has 30% more pins than its Big K counterpart, reflecting its denser brushing pattern.

The FURminator combines a steel edge, curved guard, handle, and hair-release button to prioritize loose-undercoat removal.

• Before the Big G: Inspect the coat; gently loosen accessible tangles and work in small sections.
• Before the FURminator: Remove mats and tangles first; the maker specifically warns against using its edge through them.
• During either: Work gently, follow coat direction where appropriate, and stop when the dog resists or skin becomes red.

How This Review Was Researched

Category-Specific Performance

Tangles and Mat Prevention

The Big G is the more relevant tool for a long coat that traps shed hairs and develops small tangles. Its bent pins are designed to reach into dense hair, separate it, and help create a smooth, lifted finish.

Never force it through compacted, painful mats; consult a professional.

Loose Undercoat and Seasonal Shedding

The FURminator addresses a different problem: removing loose undercoat before it falls onto floors and furniture. Its manufacturer describes the edge as reaching beneath the topcoat without cutting it when used as directed.

The company’s claim of reducing loose shedding hair by up to 90% is a manufacturer claim, not a result independently reproduced for this review. Coat type, existing tangles, technique, and the amount of naturally loose hair all affect practical results.

Coat Finish and Styling

For a Poodle-type coat, the Big G’s fluffing and shaping function matters because grooming involves keeping hair separated for combing or trimming. The FURminator’s undercoat edge has no corresponding styling purpose.

A dog with a long shedding double coat might need a gentle brush or rake first, then occasional focused undercoat removal. Use both only if the coat genuinely requires both.

Comfort and Skin Safety

Neither brand’s ergonomic design makes rough grooming safe. The Big G’s uncoated metal pin ends call for careful pressure, while FURminator warns that excessive strokes or pressure can irritate skin even with its Skin Guard.

Stop for redness, flinching, or repeated pulling away. For context, read this guide to preventing dog coat damage during deshedding.

Key Features Explained

Big G’s Long, Dense Bent Pins

Chris Christensen specifies 27 mm stainless-steel pins and a densely populated head. This arrangement can be particularly helpful on longer, curly coats where loose hair stays caught among existing strands.

Big G’s Curved, Cushioned Head

The flexible cushion allows some pin movement, while the curved brush back supports varied stroke directions. Good design still requires gentle technique.

FURminator’s FURejector and Skin Guard

The FURejector button pushes collected hair away from the grooming edge, simplifying cleanup. The curved Skin Guard is designed to limit digging at the edge, but FURminator still instructs users to avoid repetitive, forceful passes.

Real-World Usability & Maintenance

Remove trapped hair from the Big G, check for damaged pins, and store it dry; there is no specified hair-release mechanism.

FURminator recommends cleaning its edge with warm water and mild soap when necessary, then drying it completely before storage. Its Edge Guard provides storage protection, and the FURejector makes removing a gathered layer of hair easier.

Pros & Cons of the Big G

Common Issues & Fixes

What to Know Before You Buy

First identify whether your dog’s main problem is tangling or loose undercoat. A curly, low-shedding Poodle often needs systematic slicker brushing and metal-comb checks, while a shedding Labrador-type coat presents a different task.

Second, choose the correct size: Chris Christensen recommends the Medium Big G for smaller grooming areas and the Large for the body. FURminator has dog-size and hair-length variants; the Large Long Hair model discussed here is intended for dogs over 50 lb.

Third, assess skin sensitivity and coat condition before buying an undercoat edge. FURminator specifically advises against using its undercoat deShedding tool on non-shedding breeds or pets with particularly sensitive skin; see which dogs should avoid conventional deshedding.

Finally, check the current retailer listing, variant selection, and total cost rather than relying on a fixed price quoted in an older review. Chris Christensen lists a six-month warranty; confirm local terms.

Who Should Consider It / Who Should Look Elsewhere

Alternatives to Consider

Is It Worth It?

The Big G may justify its cost for routinely maintaining dense, longer coats. Its specialized design adds less value when knots are rare.

The FURminator undercoat tool is a more targeted purchase for an appropriately coated heavy shedder, especially if loose hair collects throughout the home. It still requires prior detangling, correct sizing, and restrained use; review safe deshedding frequency before establishing a schedule.

Final Verdict

For Poodles, many Doodles, and other longer coats where knots and fluffing are the primary concerns, the Chris Christensen Big G is the more logical starting tool. Its dense pins and curved cushion support detailed brushing, although the price and pressure-sensitive metal pins are real trade-offs.

For a healthy, shedding double coat, choose a correctly sized FURminator undercoat tool if loose undercoat is the main problem. Neither option should be treated as an all-purpose grooming solution, and both may be inappropriate for sensitive or damaged skin.

Frequently Asked Questions

Is Chris Christensen Big G better than FURminator?

For routine detangling and fluffing of a longer coat, the Big G is better suited. For collecting loose undercoat on a shedding dog, a correctly matched FURminator is more directly designed for that task.

Should I use a FURminator on a Poodle or Doodle?

A traditional undercoat deShedding edge is generally a poor default for a typical low-shedding Poodle coat. Mixed-breed Doodle coats vary, so assess the actual coat and ask a professional groomer when unsure.

Can the Big G remove a dog’s undercoat?

Yes, Chris Christensen states that its long pins can remove loose undercoat in dense coats. That does not make the slicker identical to a specialist FURminator deShedding edge.

How often should I use the FURminator?

The manufacturer generally recommends one or two sessions weekly, about 10–20 minutes each. Shorten or stop a session according to your dog’s coat condition and comfort.

Which Big G brush size should I choose?

Chris Christensen positions Large for the body, Medium for legs and shaped areas, and Baby for difficult-to-reach spots. Match head size to the dog’s dimensions and where you need control.

Can I use both tools on the same dog?

Sometimes, if the dog has a suitable shedding coat that also needs careful brushing. Detangle first and avoid unnecessary repeated passes; never use an undercoat tool on a coat that is not suited to it.
