Dr Yang’s Shark Chondroitin
Calcium Tablets for Dogs

Most joint supplements rely on cheap plant-based fillers. Ours don’t. Sourced from deep-sea shark cartilage from Australia and combined with bioavailable calcium and Indian Turmeric, this vet-formulated tablet rebuilds cartilage, cushions joints, and restores the mobility your dog deserves.

  • Rebuild worn cartilage & restore comfortable movement
  • Marine-grade chondroitin absorbs up to 3x faster than plant alternatives
  • Strengthen bones with bioavailable calcium for lifelong skeletal health
  • Vet formulated, increased potency — pure ingredients sourced from Australia & India

My 9-year-old lab was really struggling to get up in the mornings — we thought it was just age. Three weeks on Dr Yang’s and he’s back to meeting me at the door. His vet actually asked what we changed. This is the real deal, not another useless supplement.

Sourced from sustainably harvested deep-sea shark cartilage — the gold standard of chondroitin bioavailability. Unlike cheaper bovine or synthetic alternatives, marine chondroitin is naturally small-molecule, meaning it crosses the gut lining faster and reaches joints where it’s needed most. Paired with highly bioavailable calcium to support bone density and skeletal strength. Vet formulated with zero binders, zero artificial flavours, and zero compromise.

The Science of Sourcing

RuffDay sources every ingredient with precision engineering — hunting the globe for regions where compounds are chemically richest, then refining them to pharmaceutical purity for your pet.

Joint Support Complex

Australian Shark Chondroitin

Responsibly harvested from the pristine waters of southern Australia, our shark-derived chondroitin sulphate delivers one of the highest-density cartilage compounds available. Cold-extracted and purified to 95%+ chondroitin sulphate content, it actively cushions joints, slows cartilage breakdown, and restores mobility — especially critical for ageing dogs and larger breeds prone to joint stress.

Paired with a natural bioavailability enhancer, it delivers powerful anti-inflammatory and antioxidant action directly to joints and tissues, supporting comfort and recovery with every dose.

"I'll be honest — I was skeptical at first. There are so many dog supplements out there claiming to be 'premium' that I assumed this would just be another one… After a few weeks, I noticed my dog had more energy on walks and wasn't struggling as much getting up after sleeping."

"Super easy to add to his routine. No hassle, just something simple that actually helps. Within weeks, his coat looked healthier and shinier. That alone made it worth it."

"My dog used to slow down halfway through walks. Now he keeps up the whole time again. I just wish I started sooner. You don't realize how much these small changes matter."
