Cosheltie Breed History

The Cosheltie is too new to have a history so the histories of the parent breeds are used for this purpose. The Collie has two varieties, which are the rough-coated and the smooth-coated. The rough-coated is the more popular and commonly seen variety and is the breed of the famous dog from the television show, Lassie. This breed is believed to have originated in 1800s as a descendent of herding dogs from Wales and Scotland. The Scottish variety was known to be the more aggressive and large breed that they used to herd highland sheep, while the Welsh variety was smaller and more friendly. The Welsh Collie was used for herding goats as well as sheep. These were bred with different varieties of Sheepdogs and produced the two varieties. The first Collies showed up in dog shows in 1860 in Birmingham, England as a Scotch Sheep Dog. In 1879, the Collie was imported to America and was registered with the American Kennel Club (AKC) in 1885 where it is the 37th most popular breed of dog in the United States. The Collie Club of America was formed in 1886 and was one of the oldest specialty dog clubs in the United States. The Shetland Sheepdog is also known as a Sheltie and is actually related to the Collie. The breed was thought to be a descendent of the Scottish Collie and King Charles Spaniel, which is why it is so much smaller than the Collie. In the 19th century, these dogs were commonly used to herd small Shetland sheep, which is where they got the name Shetland Sheepdog. The breed was registered with the AKC in 1911 and is the 24th most popular breed of dog in the United States.

Cosheltie Breed Appearance

The Cosheltie is a medium-sized dog that has a medium to long coat that is rough, thick, and usually tricolored. The most common colors are black, brown, and white; brown, white, and tan; gold, brown, and black; red, black, and white; and blue merle. This breed can range from 13 to 22 inches high and may weigh anywhere from 18 to 30 pounds or more. They have a long muzzle, erect, pointed ears, and a long, furry tail. The Cosheltie actually looks like a medium sized Shetland Sheepdog or a small sized Rough Collie because they are both descendants of the same Collie and Sheepdog breed.

Cosheltie Breed Maintenance

Due to the Cosheltie’s long and rough fur, you have to brush them thoroughly on a regular basis. The best way to brush them is with a long toothed, hard bristle brush and metal comb. Many owners take their Cosheltie to get professionally groomed every four to six months to make it easier to brush them. In addition, you have to clean their ears at least once a week and check for mites, waxy buildup, and other debris to prevent irritation and infection. It is recommended that you trim her nails when needed and brush her teeth a few times a week to prevent dental problems.

Cosheltie Temperament

Your Cosheltie loves to run and herding is in her blood so she will try to herd anything that will let her. You may even find her trying to herd small children so do not leave them unattended. They are eager to please you and will go out of their way to learn what you are trying to teach them. They also share the protective nature of the Collie so they are great watchdogs and bark loudly when they want your attention. They are very intelligent and may even seem to understand you more than you think. The Collie parent breed was the star of an old television show called Lassie where the dog was able to communicate with people and saved people from all kinds of situations.

Cosheltie Activity Requirements

The Cosheltie needs at least 60 to 90 minutes of high intensity exercise every day to keep her from getting bored and out of shape. This breed enjoys herding but is also great at agility and discipline competitions, Frisbee, and flyball. Other activities they may enjoy are swimming, jogging, hiking, and going to the dog park. If you have a fenced yard, letting her run in the yard for a couple hours a day is acceptable but she also needs to spend a lot of time with her family to keep from becoming bored. Behavior problems can be avoided by making sure your dog gets plenty of exercise and attention each day.
