Shetland Sheepdog

The Shelillion is an intentional hybrid between the Shetland Sheepdog, a small, active dog with a distinctive coat that was developed on the Shetland islands, and an extremely bright and popular companion animal from Europe known as the Papillon. They require a little more brushing than average due to their long coats, although those that inherit the silky, single layer coat of the Papillon will require less maintenance than those with the copious double layer coat of the Sheltie. They are generally lively towards  both people and other animals of all ages if properly socialized and trained, although a few may tend towards timidity and standoffishness with strangers. These little dogs are quite versatile and they can thrive in either a larger home with a yard or in an apartment setting if their tendency to bark can be curbed.

Shelillon Breed History

The Shelillon is a very small designer dog, a deliberate crossbreed between the Shetland Sheepdog, a small and sturdy farm dog from the Shetland islands off the coast of Scotland, and the Papillon, one of the oldest European toy breeds, and a companion to countless royal and noble personages through the ages. The Shetland Sheepdog is a small dog with an uncertain ancestry that was developed in a part of Scotland known as the Shetland Islands. Although this dog breed resembles the rough coated Collies we are most familiar with enough to have been referred to as both the Miniature Collie and the Shetland Collie, the Shetland Sheepdog is a distinct breed that was developed by combining many different dogs breeds.  Experts speculate that many of the breeds that contributed to the Shetland Sheepdog are still in existence today, including breeds such as the Scotch Collie, the Border Collie, the King Charles Spaniel, and the Icelandic Sheepdog, but that at least one ancestor, the mysterious Greenland Yakki, has gone extinct. In the 1800s increases in tourism brought with it an interest in these little dogs as companion animals and in order to reduce their size islanders introduced additional genetics which may include Corgis, Pomeranians, and Papillons, but when their overall size became unsuitably small, breeders reinfused the Shetland Sheepdog with Collie genetics. Although the Papillon breed has been a popular companion animal in Europe since at least the 1300s, they have an equally mysterious past, with various experts placing their origins in differing countries, most commonly Belgium, France, Italy, and Spain. Through most of their history, these little Spaniels were known by many names, including Continental Spaniels, Little Squirrel dogs, and Belgian Spaniels and were characterized by drop ears. At some point during the 1800s they developed the large erect ears that we frequently see today, and were given the name Papillon, the French word for butterfly, and those that retained the drop ears were given the label of Phalene, another French word, this time meaning moth, although they are still considered the same breed in both the United States and in the United Kingdom. 

Shelillon Breed Appearance

The Shelillon is a very small canine, with a back that is slightly longer than the dog is tall, with a fine bone structure. Papillon breed dogs typically have a fairly rounded skull with a fox-like face and a thin muzzle that is slightly shorter than average, while Shetland Sheepdogs tend to have flat, wedge-shaped heads with longer, more substantial muzzles. While these crossbreeds may closely resemble one or the other of the parent breeds, they usually fall somewhere in between the two, with a slightly rounded head and a well-balanced but slightly narrow muzzle. Their eyes may be either round or almond in shape and are most commonly a dark brown, although blue and parti-color eyes do occur on occasion and they will have medium to large ears that are well furred and typically stand erect, although the ears of some Shelillon’s may be carried only three-quarters erect, and a few may inherit the drop ears of the Phalene variety of Papillon.

Shelillon Breed Maintenance

The coat for this hybrid is universally fairly long but can vary quite a bit between dogs when it comes to the density, texture, and the amount that is shed. The Sheltie has a thick, double-layer coat. Neither coat requires frequent bathing as they are naturally dirt resistant and have low odor, but both require brushing at least several times a week. Those Shelillons that inherit the silky, single layer coat of the Papillon generally are not prone to much in the way of shedding or matting, but brushing is needed both to remove dirt and debris from the coat and to prevent minor tangles, while those that have the double-layer coat of the Shetland Sheepdog shed more heavily and are more likely to develop mats, which can be particularly troublesome when they develop near the skin in the undercoat and may require brushing on a more frequent basis.

Shelillon Temperament

The Shelillon is the product of two breeds that are known to spirited, friendly, and outgoing, and is likely to inherit these traits as well, although they can be prone to separation anxiety and may become destructive if they are left alone for long periods of time or if they are not provided enough mental stimulation to keep them busy. They are quite good with children and make excellent family pets who are tolerant even with small children, but a few may be hyper-reactive to touch, loud sounds, or quick movements, making supervision very important, and they may be prone to chasing or herding other animals. Socialization and training are extremely important for this small canine to prevent negative traits such as timidness and obsessive barking from developing and to encourage positive mental growth. This hybrid is typically very bright and extremely trainable, often easily picking up tricks and excelling at competitive obedience, although they may occasionally exhibit a rebellious streak from their Papillon heritage and those that take after the Sheltie can become defensive if treated too harshly. 

Shelillon Activity Requirements

This crossbreed requires a moderate amount of exercise per day and will typically be quite content with just 45 minutes a day of vigorous activity, split up into two or three shorter sessions. However, if you are looking for a partner for slightly longer walks, the Shelillon is likely to come along gladly and do quite a respectable job at keeping up. These dogs may also enjoy other activities, such as agility training, herding exercises, mental puzzles, and games of fetch, indoors or out. It is important to take weather conditions into consideration when exercising outdoors, particularly with dogs that have the thick double coat that is most commonly seen on the Shetland Sheepdog, as they may be slightly more susceptible to high temperatures.

She is such a baby. Loves to play with the kids and cuddle with Mom. She is very scared of new things, mops, brooms, balloons, etc. She loves to hide her face in your elbow when frightened. She loves attention, but also tends to prefer space now and then.

Question - My pet

Hi. Our Shellion is 6 months old and weighs 10 1/2 lbs. I know that's average for this 'breed' but his weight hasn't changed in 3-4 weeks. He's active and we don't notice anything that would indicate a health issue. He has lost a few of his baby teeth in the last few weeks.

Hello, Many dogs will reach their adult weight around 6 months of age and really not grow or gain much weight. I think this is a normal weight for his breed. He may gain a little bit more weight but not get much bigger.
