Yes — any liquid dog shampoo works. Twist open the top, pour it in, click shut. For thicker formulas, add a splash of water for an even richer foam. One tip: stick to shampoo made for dogs, not human shampoo — a dog's skin has a different pH and is only 3–5 cell layers thick, so human products can dry it out and cause irritation.

Yes. The bristles are soft, flexible silicone — no metal pins, no hard edges — so they massage rather than scratch. That's why most dogs lean into it instead of squirming away. Gentle enough for a puppy's first bath or a short-haired cat.

Yes. The bristles are long enough to reach through the topcoat down to the skin, where dirt and loose undercoat actually sit. For heavy shedders and double coats, use slow circular strokes — it lifts loose fur as it lathers, so the hair ends up in the brush instead of your drain.

Rinse the bristles under warm water, empty any leftover shampoo, and leave the cap open to air-dry — about 30 seconds of effort. The chamber seals shut for storage, so nothing drips in the cabinet. Just don't leave shampoo sitting inside for weeks; fill it fresh per bath or two.

Then it's free. Every FurFoam comes with our 30-day sudsy-dog guarantee — try it on the muddiest, most bath-resistant dog you know, and if it doesn't make bath time easier, you get a full refund. Most owners notice the difference on the first bath: shorter, calmer, one hand on the dog the whole time.
