Oh Arthur – Shampoo Bars for Dogs

At Mason Grant, we believe our furry companions deserve to smell good too, and what use is it having a beautifully scented home if there’s a hint of doggy smell lingering?
Vegan Shampoo Bars For Dogs – Yes, they really do work!
Our Oh Arthur shampoo bars are a gentle, planet-friendly alternative to liquid shampoos. Each bar is packed with natural, dog-safe ingredients chosen to nourish the skin, clean the coat, and leave your pup smelling fresh without overpowering perfumes. They’re mess-free, long-lasting, and perfect for travel, or just keeping bath time simple. No plastic bottles, no waste, just a compact, effective clean. Plus, with our reusable tins and refill options, you can reduce your environmental pawprint while keeping your dog looking their best.
Finding the Right Oh Arthur Shampoo Bar
Every dog is different, and Oh Arthur has a bar to suit every coat and character. Delicate Dog is lightly scented and ideal for sensitive skin, with calming chamomile and lavender. Sleek Dog is our conditioning blend, perfect for adding softness and shine to coats that need a little extra love. Swamp Dog is made for the muckiest mutts; deep cleansing and deodorising for dogs who love dirt and smells. And coming soon, Diamond Dog will gently brighten light coats and lift dull tones, giving your dog a show-stopping shine. One bar, one happy pup!
How to Use Your Oh Arthur Shampoo Bar & Refill
- Get Your Dog Wet
Gently wet your dog’s coat with warm (not hot) water. Make sure they’re soaked through, this helps the shampoo lather up nicely. - Lather Up
Take your Oh Arthur shampoo bar out of its aluminium tin. Either rub the bar directly onto your dog’s coat, or lather it up in your hands or with a sponge first. - Massage In
Work the lather into your dog’s coat using your hands or a soft brush. Take your time around particularly grubby areas, think paws, belly, and back end. - Rinse Thoroughly
Rinse off all the suds with warm water until the water runs clear. Make sure no shampoo is left behind, especially around the ears and underarms. - Dry & Praise
Towel-dry your dog, give lots of praise (and maybe a treat), then stand back and admire that freshly washed fluffball. - Store the Bar
Pop your shampoo bar back in its Oh Arthur tin to keep it clean, dry, and ready for next time. Refills are available to help you reduce waste and save money..
How to Get the Best From Our Shampoo Bars
To keep your Oh Arthur bar at its best, let it dry between washes. Our handy aluminium tin is perfect for storing it between uses. Use warm water to create a rich, creamy lather, and don’t rush—massaging it into your dog’s coat helps lift dirt and makes bath time a bonding time too. A little goes a long way, especially on shorter coats. For long-haired dogs, lather in sections for better coverage. And when you’re done, pop your bar back in its tin or on a draining soap dish, ready to go again. Refill bars are available to keep your routine low-waste and wallet-friendly.
