This could never be more true in this day and age of the so-called “Designer Dogs” or “Hybrid Breeds.”
While Sheltie mixes are showing up in the form of Sheltie-Poo -Sheltiedoodle (Sheltie + Poodle), Border-Sheltie, Sheltie Inu (Sheltie + Inu), Poshies (Pomeranians + Sheltie), to name a few, they are not as popular as the Pug, Beagle, Labrador Retriever, Golden Retriever, and Poodle mixes. However, seeing one litter of these Sheltie mixes is one too many. I as many of the other responsible breeders would like to caution you in buying into this fad of designer dogs as they are no more than HIGH-PRICED mutts.
We often hear that mixed breed dogs are healthier than purebred dogs. Any ethical, responsible breeder of purebred dogs can tell you this simply is not true. When you combine two totally separate breeds, you run the risk of inheriting problems from either or both breeds. We (Reputable Breeders) medical clear our dogs of as many of the "issues" within the breed as we can before breeding. We will not breed dogs that have health issues.
If you want to experience the pleasure of owning a Shetland Sheepdog or Sheltie and all the breed has to offer, visit the American Shetland Sheepdog Association as well as other reputable breeder web sites and educate yourself on the breed's health and temperament, and buy from a reputable breeder or adopt from sheltie rescue If you want a sheltie mix, visit your local animal shelter and give a needy dog a loving home.
