| Colours are brindle & white (brownish with black stripes), black & white, blue merle (mottled blue-gray-black), sable, red or tri-colour (black & white with tan or brindle markings). Eyes must be brown except in blue merles which may have blue eyes. |
| Cardigans are prone to very few health problems, but care must be taken with young puppies to avoid back injury due to jumping from heights or being carried incorrectly by children. |
