Merle French Bulldogs – Everything You Need to Know

The Merle French Bulldogs are one of the most popular varieties of French Bulldogs. The characteristic features that differentiate these dogs from French Bulldogs’ pure breed include their unique coat pattern and saliant blue eyes. These features occur due to the presence of a gene called merle. In a merle French bulldog, these genes lighten the base coat and create dark patches. Although these dogs can have several different markings on their coat, they include dark brown or black. The dominant color is usually white, cream, or fawn, all mixed with dark colors.

Additionally, this gene may cause random pigment dilution, which lightens their eye color. For this reason, they are rare to find and are the most preferred dog breeds. Physically, they resemble French Bulldogs with their stout bodies and bat-shaped ears. In addition, they have a cordial and faithful nature which makes them a popular choice of pet.

Merle French Bulldog Health:

Merle is the gene responsible for the particular coat in Merle French Bulldogs. Unfortunately, the presence of this gene also leads to significant health defects related to the ears and eyes. Additionally, these dogs develop a bunch of complications as they are crossbreeds. When a merle is crossed with another merle, the offspring carries two merle genes. These animals are called Double merles. The double merle breeds have a greater chance of developing deformations, so they suffer from serious health issues. Therefore, it is always best to buy a puppy that carries a single merle gene. Some of the possible complications include:

Eye Defects 

  • Deformed Eyes (Small Microphthalmia): Animals suffering from this deformation develop smaller eyes as the nictitating membranes cover their eye socket or sockets. For this reason, they may be confined to an eye or both.  
  • Missing Eye or Eyes (Anophthalmia): This congenital disability occurs when one or both eyes are missing. At times, the eyes may have been formed but exist very deep inside the eye socket that the nictitating membrane covers them.  
  • Wandering Eye: This condition is characterized by eye degeneration which causes the lens to be liquefied. 
  • Cataracts: The condition causes cloudiness on the eye lens, which can lead to blindness. 
  • Starburst Pupil (Coloboma): This deformation may be associated with deafness and blindness. It is similar to an eye cleft. This condition may also lead to cataracts in dogs.  
  • Jagged Pupils: Dogs suffering from this defect are sensitive to light as their pupils have irregular edges.  
  • Blindness: Lack of eyesight in one or both the eyes 
  • Orectipia: This condition doesn’t affect the dogs severely but may get associated with other issues. In this condition, the pupils of the eye droop below their normal position.  
  • Cherry Eye: When the glands under your canine’s eyelid protrude, it appears like cherry and has to be removed surgically.
  • Dry Eye:  This painful condition dries the affected eye or creates a blue haze due to the insufficient production of tears. It can be treated with proper medication or tear drops.
  • Entropion: Entropion is when the eyelids are positioned inwards, disturbing the eye and causing eye irritation. Treatment involves correcting the eyelids surgically.

Deafness:   

  •  The merle genes affect the part of the ear responsible for hearing the speech sounds. As a result, they are unable to perceive sound that causes deafness in dogs. It is the most common among double merle Frenchies.  

Some of the other complications include:  

  • Intertrigo: When the skin folds of these dogs rub together, they result in skin inflammation or bacterial overgrowth. 
  • Brachycephalic Obstructive Syndrome (BOS): This syndrome occurs due to the skull’s small size, which leads to breathing difficulty.  
  • Perineal Hernia: The displacement of the pelvic, abdominal organs leads to this condition.  
  • Luxating Patella: A dislocated patella (kneecap) 
  • Atopic Dermatitis (Atopy): This condition occurs when your canine is exposed to a substance present in the environment, leading to an allergic reaction.
  • Epilepsy: Reoccurring seizures 

Hip Dysplasia: Hip dysplasia is hereditary. It occurs when the hip joints don’t fit into the socket of the hip bones properly. This condition causes defect or injury to the hip bones, joints and worsens without treatment.

Symptoms of hip dysplasia in dogs include:

  • Reduced activity and movements
  • Reluctance to rise, jump, run or climb
  • Lameness in the hind limbs
  • Reducing thigh muscle mass
  • Swaying, “bunny hopping” gait
  • Grating in the joint during movement
  • Enlarging shoulders
  • Pain
  • Stiffness 

Juvenile Renal Dysplasia: A genetically inherited disorder in which the kidneys dysfunction. Although there are no tests to determine this condition, it can be identified with the below symptoms:

Symptoms of Juvenile Renal Dysplasia:

  •  vomiting
  • excessive thirst
  • frequent urination
  • weight loss
  • lethargy

Merle French Bulldog Diet and Nutrition

As Merle French Bulldogs are prone to diseases, feed them a healthy and balanced diet. For this reason, you may prefer a diet consisting of organically sourced ingredients. Additionally, their diet can be supplemented with multivitamins that fuel their immunity and coat health. You can also opt for supplements like chondroitin, glucosamine, and MSM to help deal with arthritis and spinal problems. 

Merle French Bulldog Living Condition

The Merle French Bulldogs have short coats, so they need protection against cold weather conditions. For this reason, you may have to keep them covered with jackets or sweaters while taking walks during the colder months. Similarly, their smaller snouts make it difficult for them to adjust to hot weather. Additionally, these dogs are prone to separation anxiety; hence they shouldn’t be left alone for long.  

Things to Remember Before Breeding

It is vital to consider the health issues that may occur due to the cross between the breeds. Additionally, no two Merle dogs should mate, resulting in double merle offspring, which are quite unhealthy. As these dogs have narrow hips, the probability of a complicated delivery is high. Therefore, these dogs generally deliver their puppies through C-section. This situation calls for the availability of high-quality food and clean drinking water. So, check their parent’s lineage and health records from a responsible breeder to avoid ending up with a weak pet.

Cost of a Merle French Bulldog Puppy  

On average, a Merle French Bulldog mix puppy may cost around $6,000 to $8,000. The rarest Lilac Merle has been spotted at close to $30,000. This entirely depends on the sex of the puppy you chose, the breeder’s location, the show record of the parent dogs.

Check for the puppy’s parents’ health clearances before buying. Also, it is suggested to visit the breeder’s place to view the puppy’s parents’ lively and estimate how your dog may look in the future.
