Blackdog Shark Cartilage is a single-ingredient dog treat made from the cartilage of shark spine. It suits adult dogs of all breeds and sizes, and is often chosen by owners of older dogs or larger breeds prone to joint stiffness. The 100g pack is a chewy, low-processed treat with nothing added.

Shark spine cartilage is a natural source of glucosamine and chondroitin — the two compounds most commonly associated with joint and cartilage support. Because the treat is minimally processed with no additives, flavourings or preservatives, what you see on the ingredient panel is what your dog is eating. The chewy texture also gives dogs something to work on, which most enjoy.

Owners tend to reach for these when they want a functional treat rather than a training reward — something that does a job while their dog chews. The single-ingredient format also makes it a safer option for dogs with sensitive stomachs or known food intolerances.
