How Rare Are Blue Merle Shetland Sheepdogs? (2025)

Blue Merle Shetland Sheepdogs are a rare coat variation, making up less than 10% of the breed. Their blue-gray marbled coat comes from the merle gene, which requires careful breeding to avoid health issues. To prevent blindness and deafness, ethical breeders avoid double merle pairings. Their rarity and striking appearance make them highly valued.

📖 According to the American Kennel Club (AKC), Sheltie color genetics follow strict breeding guidelines to ensure healthy puppies.

Shelties were developed in the 1800s in the Shetland Islands of Scotland for herding livestock. Their ancestors include Rough Collies, Border Collies, Icelandic Sheepdogs, and King Charles Spaniels, giving them intelligence, agility, and a strong work ethic. Blue Merle Shelties have the same temperament and abilities as other Shelties.

Their herding ability and temperament align with the breed standards recognized by the United Kennel Club (UKC).

Yes, Blue Merle Shelties need a high-protein diet with essential fatty acids and antioxidants to support their energy levels, brain function, and coat health. They thrive on lean proteins like chicken, fish, and lamb, which provide the muscle-building amino acids needed for their active lifestyle. Their double-layered coat benefits from Omega-3 and Omega-6 fatty acids, which help maintain a shiny, soft coat and hydrated skin.

Key Nutrients for a Blue Merle Sheltie’s Diet

🥩 High-Quality Protein – Chicken, fish, and lamb provide the amino acids needed for muscle growth and sustained energy. Always choose real meat over by-products.

🐟 Healthy Fats (Omega-3 & Omega-6) – Found in salmon, flaxseed, and fish oil, these support a soft coat, reduce inflammation, and promote brain health.

🥦 Antioxidant-Rich Vegetables & Fruits – Blueberries, carrots, and spinach boost immunity, improve vision, and aid digestion.

🥔 Complex Carbohydrates – Brown rice, sweet potatoes, and oatmeal provide slow-burning energy, keeping Shelties active and full longer.

🐾 Joint & Bone Support – Glucosamine from green-lipped mussels or bone broth helps protect joints and prevent arthritis in active Shelties.

Yes, Blue Merle Shelties have a thick double coat that requires consistent maintenance. Their outer coat repels dirt, while their dense undercoat sheds heavily twice a year, requiring frequent brushing to prevent matting and tangles. Owners should use a slicker brush and an undercoat rake to manage loose fur and reduce shedding.

Grooming Routine for Blue Merle Shelties

🖌️ Brushing (3-4 times per week) – Use a slicker brush and undercoat rake to remove loose fur, prevent matting, and control shedding. Increase brushing to daily during seasonal shedding.

🛁 Bathing (Every 4-6 weeks) – Use a mild, dog-friendly shampoo to keep their coat clean and soft. Avoid over-bathing, as it can strip natural oils and cause dry skin.

✂️ Trimming (As needed) – Trim fur around the paws, ears, and sanitary areas to prevent dirt buildup and matting. Regular trimming keeps them neat and comfortable.

🦷 Teeth Cleaning (2-3 times per week) – Brush their teeth using dog-specific toothpaste to prevent plaque buildup and bad breath. Dental chews can also help maintain oral hygiene.

👂 Ear Cleaning (Weekly) – Check their ears for wax buildup, dirt, or signs of infection. Use a vet-approved ear cleaner to keep their ears healthy and odor-free.

✂️ Nail Trimming (Every 3-4 weeks) – Trim their nails to prevent painful overgrowth and posture issues. If you hear clicking sounds on the floor, it's time for a trim.

🏥 Professional Grooming (Every 2-3 months) – While regular home grooming is essential, a professional groomer can help with thorough coat maintenance, trimming, and deep cleaning.

Since their long coat is prone to tangles, daily grooming sessions help maintain a clean, healthy, and mat-free coat. With proper care, their luxurious fur remains soft, shiny, and manageable.
