Piebald appears to be the allele responsible for color-headed whites. (Sable & White, Tri-Color, & Blue Merle) We are a short driving distance from the states of Ohio, Indiana, Wisconsin, and Pennsylvania. If you have to ask this question, chances are you’ve never met a collie in person! The AKC standards dictate that a male collie should stand between 24 and 26 in. First is the sable and white color, or the “Lassie” color. The rough collie is a member of the herding group because Scottish shepherds originally used the dogs to herd their sheep. Imagine my surprise when Leigh Anne called one day a few years ago to say that my tri rough Wiggy has a merle gene. When your collie is shedding, you want to make sure that you groom them properly to prevent matting and tangles in their coats. A typical illustration you might see in a book about collies. In fact, learning new behaviors is a great way to make sure your dog is getting all the mental stimulation that they possibly can. The brown gene’s phenotype (appearance) is expressed, so it is epistatic while the suppressed black gene is hypostatic, and simply darkens the brown. These dogs originate from Scotland, where shepherds bred them for herding sheep and other livestock. They love to please, and in doing so, love to play! Though exceptions do exist, collies are usually loving, family-oriented dogs. This breed is proud and incredibly intelligent. Harlequin in Danes is located on a separate chromosome than the merle gene. In testing the DNA from several different normal grays, she discovered that these Collies are actually blue merles with an additional mutation that eliminates the visible spots and produces a nearly solid grey coat. There is a story behind this new logo, a story about a Collie we bred and had the extreme privilege of knowing – A Collie by the name of Noah…Read More! According to the Collie Club of America, most collies live between 10 and 14 years. Epistasis means that the black recessive gene in a tri-factored sable is suppressed by the dominant brown gene that we call sable. With that said, for the most part this breed is friendly and outgoing with other dogs. Many people are surprised to learn Collies actually come in a variety of colours and people are often even more surprised to learn that Collies actually come in two distinct coats - the Rough-coated Collie and the Smooth-coated Collie. Harlequin is not a color gene but rather a coat pattern. Some other members of the herding group include the Australian Shepherd, Bearded Collie, German Shepherd, Border Collie, Old English Sheepdog, Pembroke Welsh Corgi, Shetland Sheepdog, and more.

Queen Victoria first discovered the dogs while staying in the Scottish Highlands, and soon after became quite enamored with them. The fourth and final collie color is the white. Another high point to this breed’s reputation is their loving and social nature. However, you should always approach a dog with caution, no matter what the breed, and never pet a dog or allow your child to pet a dog without asking first. While this breed is overall quite healthy, they do have two primary health issues that you should watch out for. If a hair follicle does not receive melanosomes, the hair strand it forms is un-pigmented, white, as in the majority coat of a white Collie or the neck region of colored collies (from the Irish pattern gene). The merle gene turns some parts of a black coat to grey by not allowing the black color to come through completely. They often have tan near their face and on their legs like the tri-colored color does. The Furminator Grooming Rake has wide, rotating teeth that work much more efficiently in your collie’s dense coat. Therefore, if a collie inherits a dominant brown gene from each parent, he/she is a “pure for sable” (homozygous for brown). The unwanted effects of doubling up on merle in one individual need explanation. Many collies still retain these herding traits today, and some people still use collies to herd livestock. Also, no health related problems are associated with the mutated merle gene that produces solid greys than with any other Collies. Most of us know that in our breed brown is dominant and black recessive. Some of these links are affiliate links where we may earn commissions on purchases. It turns out that mutations occur in this string of “A’S” quite often as cells divide, decreasing the length of the stretch of “A’s”. while female collies should weigh between 50 and 65 lbs. Dr. Clark was able to sort out the mystery of normal grey Collie coat color (no relationship to  lethal greys). Conversely, you should avoid using punishment with any animal. As is the case with height, the AKC standards dictate that female collies should weigh slightly less than their male counterparts. At that time, Dr. Clark et.al had mapped the merle gene in all breeds adding significantly to knowledge of merle genetics. For more information about fixing problem behaviors, click here. They have a lot of hair, and they shed their dense undercoat twice per year. When you next look at a blue merle Collie, look at the spots of black and grey on its body which give it its beautiful coat and think that you are literally looking at mutations. So while eye size, shape and set are genetically controllable through selective breeding, the presence of blue in the eyes of merles is not. If you can maintain its physical needs, you should also ensure that you are giving your dog all the mental exercise you can. I asked for a recheck! This breed is well known for their outstanding temperament. Eye problems, and ivermectin sensitivity. A puppy inherits one color gene from each parent.

Because the merle gene is apparently in close proximity on the strand containing genes for normal eye and ear development, doubling the merle gene reduces pigmentation necessary for proper development. 12 Things Dog Owners Can Do With Carabiners That Will Blow Your Mind, The Red Fox Labrador – Your Ultimate Breed Information Guide, 10 Rottweiler Mixes We Can’t Get Enough Of, 15 Things You Should Know Before Getting A Chihuahua Terrier Mix, The Pharaoh Hound – Your Ultimate Breed Information Guide.
