Characteristics of Blue Merle Australian Shepherd Dogs

Breed Standard

Blue Merle Australian Shepherd Dogs are a unique and popular variation of the Australian Shepherd breed. According to the breed standard, the desirable traits for Australian Shepherds are as follows: they should exhibit strong herding and guarding instincts and be highly intelligent, with a deep connection and love for their human families. These dogs are also known for their energy, agility, and willingness to please. Blue Merle Aussies share these characteristics with other color variations of the breed.

Coat and Coloring

The most distinguishing feature of Blue Merle Australian Shepherds is their coat color. The term “merle” refers to a genetic pattern that creates a patchy or marbled appearance on the dog’s coat. In the case of Blue Merles, this pattern causes the black pigment to appear diluted, resulting in a combination of blue, gray, black, and white hues.

The beautiful and unique coloring of Blue Merle Aussies makes them highly sought after. However, it’s important to note that their coat color does not have any influence on their temperament or health when compared with other Australian Shepherds.

Eye Color Variations

Another captivating trait of Blue Merle Australian Shepherds is the variation in their eye colors. These dogs may have blue, brown, hazel, green, or amber eyes, or any combination of these colors. Some even have heterochromia, which refers to having two different colored eyes. This phenomenon is fairly common in merle-colored dogs due to the same genetic factors that cause their coat patterns.

Size and Weight

Regarding their size and weight, Blue Merle Australian Shepherds are similar to other Australian Shepherds. Males typically stand between 20 to 23 inches (51 to 58 cm) tall and weigh around 50 to 65 pounds (23 to 29 kg). Females are slightly smaller, with heights ranging from 18 to 21 inches (46 to 53 cm) and weights between 40 to 55 pounds (18 to 25 kg).

Health and Lifespan

Common Health Issues

As a knowledgeable dog enthusiast, I can confidently share that Blue Merle Australian Shepherds, like any other dog breed, face certain common health issues. First on the list is hip dysplasia, a genetic condition that affects the hip joint. Additionally, they are prone to eye disorders such as cataracts, progressive retinal atrophy (PRA), and collie eye anomaly (CEA). These conditions can lead to vision loss if not properly treated.

Another concern for Blue Merle Australian Shepherds is MDR1 (Multi-Drug Resistance 1) gene mutation, which can cause sensitivity to certain medications. It’s important to consult your veterinarian about the necessary precautions if your Aussie carries this mutation.


Blue Merle Australian Shepherds have a lifespan of 13 to 15 years. To maintain their health and prolong their life, it’s crucial to provide them with regular veterinary care, proper nutrition, and adequate exercise. Engaging in mental stimulation activities can also contribute to their overall well-being.

Here are some general tips to keep your Blue Merle Aussie in peak condition:

  • Regular veterinary check-ups: Early detection of potential health issues is crucial for effective treatment and prevention.
  • Balanced diet: High-quality food that is appropriate for their age, size, and activity level will help maintain their health.
  • Exercise: As a high-energy breed, Blue Merle Australian Shepherds require regular physical activity to prevent obesity and stay in shape.
  • Mental stimulation: Engaging their minds through training, puzzle toys, and interactive games contributes to their overall well-being.

By following these guidelines, you can optimize the health and happiness of your beloved Blue Merle Australian Shepherd throughout their lifetime.



Temperament and Lifestyle


Blue Merle Australian Shepherds are known for their friendly, loyal, and affectionate nature. They are intelligent dogs that enjoy being around their human family members. This breed, like other Aussie varieties, thrives on human interaction and develops strong bonds with their owners. They are also known for their playful behavior, which makes them an excellent choice for families with children or other pets at home. Blue Merles are social animals and enjoy spending time with their family, making them well-suited for a variety of households.

Activity Level

Being an active and energetic breed, the Blue Merle Australian Shepherd requires a high level of physical exercise and mental stimulation. Daily outdoor activities such as walks, runs, and playtime are essential for their well-being. The following list highlights some suggested activities for your Blue Merle Aussie:

  • Playing fetch: Aussies love to chase after balls and other toys, so playing fetch is an excellent way to engage their active minds.
  • Agility training: Australian Shepherds excel in agility courses, making this a fun and challenging activity for your dog.
  • Hiking: If you’re an outdoor enthusiast, bringing your Blue Merle Aussie on hikes can provide a great bonding experience and a good workout.

It’s important to keep in mind that these dogs are not suited for apartment living, as they require ample space to roam and play.


Training your Blue Merle Australian Shepherd should begin early, as their intelligence and eagerness to please make them fast learners. Positive reinforcement techniques such as treats and praise work well with this breed, helping to establish a strong bond and mutual understanding between you and your dog. As a highly trainable breed, you can teach them a wide range of commands and tricks.

Due to their herding heritage, these dogs have a strong instinct to nip at heels or chase smaller animals. Therefore, it’s essential to teach your Blue Merle Aussie proper manners and boundaries, especially when interacting with other pets or children.

Remember, regular socialization with other dogs and people is crucial for developing a well-rounded and confident Blue Merle Australian Shepherd. By understanding their temperament and catering to their lifestyle needs, you can ensure a happy and healthy life for your Aussie companion.

Care and Maintenance


As a Blue Merle Australian Shepherd owner, I can tell you that grooming is an essential aspect of their care. These dogs have a beautiful, thick double coat that requires regular brushing to prevent matting and keep it healthy. I usually brush my dog’s coat at least once or twice a week using a slicker brush and an undercoat rake. During shedding seasons, I increase the brushing frequency to manage the loose hair. It’s also important to trim their nails monthly and check their ears for any signs of infection. Regular grooming sessions also provide a fantastic opportunity for bonding with your dog.


Blue Merle Australian Shepherds are highly energetic and intelligent dogs. In my experience, they need daily physical and mental stimulation to keep them happy and healthy. I take my Aussie for a long walk or a run every day, and we also engage in various activities such as:

  • Playing fetch
  • Agility training
  • Herding exercises
  • Obedience training

Remember that these dogs excel in various dog sports, and participating in such activities can be a great way to channel their energy and keep them mentally challenged.

Nutritional Needs

To ensure the health and well-being of my Blue Merle Aussie, I pay close attention to their nutritional needs. I feed my dog a high-quality, well-balanced diet, rich in proteins, healthy fats, and essential nutrients. It’s vital to be mindful of your dog’s age, size, activity level, and any health concerns when determining the appropriate diet and portion size.

As a starting point, I suggest:

  • Puppies: 3-4 small meals per day
  • Adults: 2 meals per day
  • Seniors: 2 meals per day, with adjustments for reduced activity

Always consult your veterinarian if you have concerns or questions about your dog’s dietary requirements.

Weather Tolerance

One of my favorite things about Blue Merle Australian Shepherds is their impressive weather tolerance. Their double coats offer protection against both hot and cold conditions, which is why they can adapt well to different climates. However, it’s essential to monitor your dog and provide appropriate care during extreme weather conditions. In hot climates, ensure they have access to shade and fresh water, and avoid exercising during the hottest times of the day. In colder climates, a well-insulated dog house or shelter is crucial if your dog spends extended time outdoors. Overall, taking these weather precautions ensures a comfortable and safe environment for your Aussie.
