Blue and lilac French bulldogs are far more expensive than other colors. While they seem very similar at first glance, the key difference between lilac French bulldogs and blue French bulldogs is that the brown gene is absent in lilac French bulldog puppies, giving them a more purple hue.  

They are both one-of-a-kind and leave many breathless. In this article, we uncover their differences, no matter how small. Let’s dig in!


French Bulldog Coat Colors

Lilac French bulldogs are typically a grayish color with a lilac hue.



Some may argue that one of the benefits of any type of lilac Frenchie is that it is a perfect companion dog because it is small and easy to care for. Blue French bulldogs are tiny, reaching up to 13 inches in height, and the lilac rarely exceeds 12 inches.


This should be considered while creating a diet and activity plan for their French bulldog, as it has a significant impact on the dog’s weight. A lilac French bulldog is similar in size and weight to a typical French bulldog, standing approximately a foot tall at the shoulder and weighing around 20 pounds. A blue French bulldog can weigh up to 28 pounds.

Coat Type

Lilac French Bulldog

Lilac French bulldogs have a lovely coat that’s more muted compared to a blue French bulldog.


There are now lilac Frenchies in existence because of selective breeding amongst dogs that have a characteristic purple or blue shine to their coat. This dog’s coat may look like that of a blue French bulldog when it’s born. However, its coat lightens and develops a characteristic lilac hue as it ages. The coat of lilac French bulldogs is less dense than that of the standard breed.


Due to their scarcity, both the lilac and blue bulldogs are currently in high demand. Blue and lilac coat colors, on the other hand, were traditionally thought to be unpleasant. The coat of the lilac French bulldog is a lovely shade of lilac. This disorder is caused by the same diluting gene that causes blue hair. The coat’s color is a pale greyish brown, according to some. Their eyes and lips have delicate pink markings, and their noses are usually light pink or greyish brown in color. The most obvious distinction is that the blue French bulldog has a short blue coat that distinguishes it.

The blue French bulldog is a small, friendly dog with a relaxed demeanor. The temperament of the lilac French bulldog is like that of another Frenchie’s; it enjoys being handled and played with! It will approach humans in the hopes of receiving affection. Lilac dogs are usually laid-back and uninterested in rigorous effort.


French bulldog breeds are smart dogs so most of the time training them is not hard. The key is to keep it fun and easy. Because of their particularly small size, the lilac French bulldogs should not be encouraged to participate in high-intensity training or agility courses.

The blue French bulldog is not particularly athletic, it’s best to avoid any obstacles that require jumping, twisting, or climbing unless they’re explicitly marked as being suitable for a little breed. Lilac French bulldogs only need one daily exercise session.

Are Lilac French Bulldogs Rare?

The lilac coat color in French bulldogs is just one among several variations.

Nevertheless, it stands out as one of the rarest. In fact, it’s so uncommon that only experienced breeders can attain it without resorting to any harmful inbreeding practices.

A plain lilac French Bulldog puppy might cost about $7,000, while a lilac merle can be pricier, going up to $8,000. The rarest and most expensive colors, such as platinum and fluffy, are extremely valuable to breeders, which is why their prices range from $6,000 to as high as $12,000.

Health Factors

Life Expectancy

French bulldogs are notorious for having a range of health problems and are not known to live for extended periods of time. The average lifespan of a lilac French bulldog is roughly 12 years. Blue French bulldogs can live up to 14 years on average if they stay healthy.

Health Problems

The French bulldog isn’t known for being an extremely healthy breed. They are prone to allergies, intervertebral disk disease, hemivertebrae, hip dysplasia, brachycephalic airway syndrome, cleft palate, and other ailments. The blue French bulldog is known for having the most health issues. “Blue dog alopecia,” which also affects other dog breeds, is the source of the skin coloration in a sizable percentage of blue French bulldogs.

Regrettably, many of the brachycephalic issues come from the breeding of these animals to produce the shortened snout and flattened faces that they are so commonly known for. While these aesthetics make them adorable, they don’t do the lilac, or the blue French bulldogs any health favors. Another associated issue from the airway issues is that the dogs overheat quicker than most breeds without ideal respiration.
