DNA/Genetic testing on breeding stock is something that the BTCC doesn't take lightly. The best way to produce healthy, happy puppies is to ensure that their parents are genetically sound. Nothing is ever 100% guaranteed in nature, but DNA testing of breeding prospects assists breeders in making informed decisions on breeding pairs.

CONGENITAL OR DEVELOPMENTAL DISORDER
Patellar Luxation is a condition in which the kneecap is displaced or dislocated from the knee joint where it belongs. Unilateral (only one kneecap is out of place) or Bilateral (both kneecaps are our of place) cases can be presented. This condition is common in all toy breeds, and may be a condition the dog was born with (congenital) or may it develop later in life (developmental).
