Of all the dog breeds on the planet, this one is known as being most prone to deafness, a congenital condition.
They Can Have a Big Heart
Dalmatians often have a disorder known as ventricular enlargement, also known as an enlarged heart.
Bronzed Fur
Known as a syndrome, Dalmatians whose fur takes on a bronze tinge was once thought to be caused by an irregularity in the animal's uric acid metabolism. Today, however, dermatologists believe it to be allergic dermatitis.
Waardenburg-Klein Syndrome
This genetic disorder in Dalmatians affects their pigmentation, evidenced by dogs having pale, usually blue, eyes, often two different colors (heterochromia irides) and amelanotic skin, meaning their skin isn't normally pigmented.
Urate Uroliths (Bladder Stones)
This condition is associated with the same genetic predisposition of the absence of white hairs in spots. Dogs with this "high urate excretion" are often chosen to breed with Dalmatians with lots of dark spots.
