Question 1

How do French Bulldog colors work genetically?

Accepted Answer

French Bulldog coat color is determined by 6 main genes: D (dilution→blue), B (brown→chocolate), E (extension→cream), K (dominant black→brindle), M (merle pattern), and L (long hair→fluffy). Each puppy inherits one copy from each parent.

Question 2

What is a Double Merle and why is it dangerous?

Accepted Answer

Double Merle (M/M) occurs when both parents carry the merle gene and a puppy inherits two copies. This causes deafness, blindness, and other serious health issues. Never breed two merle dogs together. Our calculator warns you about this risk.

Question 3

Can two standard-colored dogs produce exotic puppies?

Accepted Answer

Yes! If both parents are carriers of recessive genes (D/d, B/b, L/l), they can produce exotic-colored puppies. For example, two standard-looking dogs that are both D/d carriers have a 25% chance of producing Blue (d/d) puppies.
