History of Collies

Originating in Scotland, collies were popularized by Queen Victoria, who stayed at the Balmoral Castle in the Scottish Highlands and fell in love with the breed. This was a local herding breed that was transformed from a common shepherd dog to a symbol of nobility. Historians believe that collies existed in Scotland thousands of years before that, however.

Written records of collies date back to the early 1800s, and the breed became popular in America in the 1900s. The American Kennel Club recognized the collie as a dog breed in 1885, and the Collie Club of America was formed in 1886. Authors have featured collies in books, and filmmakers have included collies in their shows and movies. The famous television show, Lassie, was about a collie and made the breed a favorite companion among children.

Caring for Collies

Collies have very showy coats that require a little extra care for grooming. They also have an elegant shape and are athletic as long as pet parents keep up with regular exercise. Yet these are well-balanced dogs that like their active time and their chill time too. Unlike some other breeds, collies are not one-person dogs and will bond with multiple people in a family and even new friends too.

Here are some general tips for taking the best care of a collie:

  • Houses with fenced yards

  • Rough collies may require extra grooming compared to smooth collies

  • Spayed females do a big shed once per year

Common Health Problems of Collies

Collies have a moderately long life span and typically live between 12 and 14 years. The Collie Health Foundation has researched various ways to improve the health of this breed. The national breed club for collies recommends that dogs get a PRA Optigen DNA test and MDR1 DNA test to verify if any serious health conditions are present. You can avoid many health issues with your collie if you get your dog from a responsible breeder who has done the recommended health checks and clearances. Skin, eye, and joint issues are common with collies, as well as allergies and sensitivities to medications.

These are some of the most common health issues that arise with collies:

  • Nasal solar dermatitis (skin that peels and oozes, may lead to cancer)
  • Collie eye anomaly (inherited condition that can cause blindness)
  • Dermatomyositis (autoimmune skin disorder)
  • Progressive retinal atrophy (eye disease)
  • Nodular granulomatous episclerokeratitis (immune disorder)
  • Hip dysplasia
  • Allergies to food and environmental conditions
  • Sensitivity to anesthesia, insecticides, and some heartworm medications with ivermectin

Diet and Nutrition for Collies

Collies need two to three cups of dry dog food per day, divided into two meals. It can be difficult to recognize whether a collie is overweight or underweight because of their thick coat. As a general rule, adult collies need between 990 and 1280 calories per day. A few recommended dog foods for collies are Royal Canin Large Adult Dry Dog Food, Purina Pro Plan Adult Complete Essentials Shredded Blend Lamb & Rice, and Hill’s Science Diet Adult Large Breed Light Chicken Meal & Barley Dog Food.
