Red Merle Dog: Understanding the Genetics and Risks

The Red Merle dog is a beautiful breed known for its distinctive coat pattern. It's created by a specific genetic combination that affects the production of two types of melanin: eumelanin and pheomelanin.

Red Merle dogs have a higher risk of deafness due to the genetic mutation that causes their coat pattern. This is because the mutation can affect the development of the auditory nerve.

The genetics behind the Red Merle coat pattern are complex, but essentially, it involves a dominant gene that codes for the production of eumelanin. This gene is responsible for the black and blue pigmentation in the dog's coat.

The risk of deafness in Red Merle dogs is higher than in other breeds, with studies showing that up to 30% of them may be affected.

Red merle dogs can be found in a variety of breeds, each with their own unique characteristics.

The Australian Shepherd, for example, is a popular breed that carries the merle gene, resulting in a beautiful red merle coat.

Merle is also accepted in the Pyrenean Shepherd breed, where it adds a striking touch to their coats.

Here's a list of some breeds that carry the merle gene and are recognized by the AKC:

Blue merles are actually grey, and they can appear like a tri-color dog with black, white, and tan patches, but with the black patches looking faded.

The two most commonly seen types of merle are blue merles and red merles.

Red merles have faded patches of red and can look more mottled than blue merles.

Only certain breeds produce red merles, and the strength of the other colors in the dog's coat can vary.

Some merles can have extremely pale coloring all over, while others can have quite strong patches of color.

Blue merles with no tan markings at all are known as bi-blues.

The world of dog breeds is incredibly diverse, with many different types and varieties to choose from.

Some breeds are recognized by the AKC as having merle as an acceptable color.

If you're considering bringing a merle-colored dog into your family, it's essential to choose a breed that's known to carry this color.

The following breeds are recognized by the AKC as carrying merle and are considered acceptable:

The red merle pattern is caused by a specific genetic combination. All merle dogs have the genotype Mm, meaning they have one allele for merle and one for non-merle.

To understand why merle dogs have this pattern, we need to look at their genetics. If you breed a merle (Mm) to a non-merle (mm), you'll get a litter with half merle and half non-merle puppies.

Merle dogs get their distinctive pattern from the interaction of two alleles - one for merle and one for non-merle. This combination creates the characteristic patches of color on a merle dog's coat.

Breeding two merles together (Mm X Mm) produces a quarter of non-merle (mm), half merle (Mm), and a quarter double-merle (MM). Double merles don't look like typical merles, instead they're mostly white with merle patches.

Red merle dogs can be prone to certain health issues due to the merle gene. These issues can range from mild to severe and may affect various aspects of a dog's health.

One of the most significant concerns is hearing problems, with studies showing that 36.8% of dogs with the merle coat pattern (Mm) suffer from hearing issues, including mild to complete deafness.

Dogs with the merle gene are also more likely to experience eye abnormalities, with one study finding a significantly greater frequency of eye problems compared to non-merle dogs.

In addition to ocular and auditory issues, merle dogs may also be at higher risk for skeletal, cardiac, and reproductive abnormalities.

Here's a breakdown of some of the potential health issues associated with the merle gene:

Australian Shepherds are highly intelligent dogs that are easy to train, making them a popular choice for active families. They were first formally recognized by the United Kennel Club in 1979 and by the American Kennel Club in 1991.

Their popularity can be attributed to their intelligence, capability, and their involvement in rodeos, where they would help keep bulls in order and entertain the audience with tricks. Famous Australian Shepherd owners include Steven Spielberg, Steve Jobs, and Amanda Seyfried.

Australian Shepherds are loyal, energetic, playful, and fun-loving dogs that require an hour or two of exercise on a daily basis. They shed heavily during shedding season, so be prepared for a lot of undercoat raking during these periods.

Australian Shepherds have gained popularity over the years, thanks to their intelligence and trainability. They're highly sought after as herding and ranch dogs.

The American Kennel Club (AKC) first formally recognized the breed in 1991.

This is relatively late, considering the breed's long history.

The United Kennel Club recognized the breed as early as 1979, a full 12 years before the AKC.

Australian Shepherds must meet specific height requirements, with males ranging from 20 to 23 inches and females from 18 to 20 inches.

They should also be slightly longer than they are tall.

Australian Shepherds are known for being loyal, energetic, playful, and fun-loving dogs.

They require an hour or two of exercise on a daily basis, so they're not suited for those without an active lifestyle.

If you have small children or other pets, be aware that some Australian Shepherds may try to "herd" them due to their natural instinct, but this can be trained out of them.

Their coat patterns and colors can vary, but the merle pattern is a key characteristic.

Staffordshire Bull Terrier breeding motivations are often driven by misguided reasons. Some breeders think that merle dogs are where the money's at, but it's simply not true.

The decision to breed merle dogs is often based on short-term gains, rather than long-term health and well-being of the dogs. Quality, fully health tested Staffords meeting the breed standard will always produce healthier dogs.

Merle breeders may also believe that there's higher demand for "unique and rare" colors in the Staffordshire Bull Terrier breed. However, color can be added without merle and the issues that come with it.

Staffords already come in many wonderful colors, piebalds and brindles, so there's no need to sacrifice structure, health, temperament for a short-term fad.

Australian Shepherds make great pets for active families, especially those who enjoy spending time outdoors. They're loyal, energetic, playful, and fun-loving, making them perfect companions for a lively lifestyle.

If you're thinking of bringing an Aussie into your home, be aware that they can have a strong herding instinct. This might lead them to accidentally knock over small children or disturb other pets, but it's not a sign of aggression and can be trained out of them.

Australian Shepherds require a lot of exercise - at least an hour or two per day. They're not suited for families who don't have an active lifestyle or who prefer low-energy dogs.

During shedding season, Australian Shepherds shed heavily, so be prepared for regular undercoat raking.
