The American Bully Merle is a unique and captivating breed that has gained popularity worldwide.

One thing to note about the American Bully Merle is its genetic makeup, specifically the merle gene mutation that gives it distinctive coat patterns.

This mutation can come with some health risks, including deafness and vision problems in both parents and offspring.

American Bully Merle Health

Unfortunately, there are health problems associated with the merle gene mutation that you should know about if you're considering getting an American Bully puppy.

The merle coat pattern is popular because it's unusual and unique, but it can lead to eye or ear deformities in double merles, which are dogs that have two copies of the merle gene. This can result in complete blindness and deafness.

It's essential to understand that breeding two merle-coated American Bullies together increases the risk of producing a disabled puppy, so it's crucial to do your research before bringing home a new furry friend.

Gene Mutation Health Risks

The merle gene mutation can cause significant health problems in dogs. Unfortunately, this is especially true when two merle-coated dogs are bred together.

Double merles, which occur when both parents have the merle gene, are highly likely to suffer from eye or ear deformities, and at worst, complete blindness and deafness. This is a serious concern that has led some organizations, like the Kennel Club in the UK, to ban breeding double merles altogether.

The health risks associated with the merle mutation can be devastating for dogs and their owners. It's essential to understand these risks before deciding to breed or purchase a dog with this coat pattern.

Detailed Summary

The American Bully Merle coat color is determined by a genetic test that checks for the M (merle insertion variant) Allele of the PMEL gene.

This test can also determine the approximate size of the M allele(s), which has been associated with different merle coat colors and patterns. The size of the M allele(s) present in a dog can impact the expression of the PMEL gene, affecting eumelanin (black pigment) areas but not phaeomelanin (yellow/red) pigmented areas.

The Merle gene is inherited in a dominant fashion, meaning that only one copy of an M allele is necessary for a dog to display some variation of the merle coat color or pattern. This can result in random dilution of eumelanin leaving patches of normal coat color within areas of diluted pigmentation.

Two copies of the large M allele are thought to cause significant white areas of the coat, eye abnormalities, and deafness due to the death of skin melanocytes, retinal pigment cells, and melanocytes of the inner ear. This is a serious health concern for American Bully Merle dogs.

Breed Standards and Testing

The American Bully Merle breed has a unique genetic makeup that affects its appearance and characteristics.

To ensure consistency with breed standards, responsible breeders test their dogs for certain genetic traits, including merle pattern genetics.

This testing helps identify potential health risks associated with the merle gene in American Bully Merles, such as deafness or vision impairment.

Standard

The standard for a breed is set by its governing body, such as the American Kennel Club (AKC) or The Kennel Club (KC).

In most cases, these standards are based on specific physical and behavioral characteristics that have been established over time through careful consideration of the breed's history, purpose, and typical traits.

The AKC, for example, has a detailed description of the ideal Poodle, including its size, coat type, and temperament.

Breed standards typically include information about the dog's body structure, such as its height, weight, and skeletal proportions.

In addition to physical characteristics, breed standards often address the dog's behavior, including its level of energy, trainability, and potential for herding or guarding instincts.

Testing Summary

The M Locus (Merle) coat color test is a reliable way to determine if a dog carries the M allele of the PMEL gene.

This test will also give you an approximate size of the M allele(s), which can help you understand the potential merle coat colors and patterns your dog may display.

Merle is inherited in a dominant fashion, meaning that only one copy of an M allele is necessary for a dog to show some variation of the merle coat color/pattern.

The M allele impacts canine coat color by altering the expression of the PMEL gene, which affects eumelanin (black pigment) but not phaeomelanin (yellow/red) pigmented areas.

Dogs with two copies of the M allele large enough to produce the merle coat color may also experience significant white areas of the coat, eye abnormalities, and deafness.

Care and Veterinary Advice

American Bully care tips are essential for a happy and healthy life. American Bullies have short coats that are fairly low-maintenance.

Regular grooming is necessary to keep them clean and healthy. Schedule regular veterinary check-ups to ensure your American Bully remains healthy.

Tom Novo, an enthusiastic owner of an eight-year-old American Bully named Rocky, recommends keeping up with vaccinations, parasite control, and other recommended healthcare measures.
