The Collie is a medium, lithe herding dog standing 22 to 26 inches tall and weighing 50 to 75 pounds, with a typical lifespan of 12 to 14 years. It comes in two coat varieties, rough and smooth, both seen in sable and white, tricolor, blue merle, or white.

An elegant wedge-shaped head, mobile ears, and almond eyes give the Collie a wide range of expressions. The breed is devoted, proud, and graceful, swift and athletic, and famously fond of children.

Collies belong to the Herding Group and were recognized as a breed in 1885. Bred in the United Kingdom, they have long been prized for their loyalty, intelligence, and steady character.

Care

The routines that matter most for this breed. Open one at a time.

Nutrition

Good nutrition supports a Collie's skin, coat, and general well-being. Collies do well on a quality dog food formulated for their life stage, whether puppy, adult, or senior. Diets labeled for all life stages are not always the right fit, so check with your veterinarian before settling on one and before deciding when to transition by age and health.

The right amount depends on weight, activity, age, and any existing conditions, so use the bag's calorie count per cup and your vet's guidance to set portions. As a rough guide, a 60-pound dog typically needs 1,000 to 1,200 calories a day. Less active dogs may need under 1,000, while very active dogs may need over 2,000. Measure meals to avoid overfeeding, and keep treats to no more than 10% of daily calories.

Most Collies do well on two meals a day, usually breakfast and dinner. Feeding smaller meals through the day rather than one or two large ones, and avoiding intense exercise around mealtimes, supports a comfortable belly. Some Collies bolt their food without chewing, so a slow-feed bowl can help them slow down.

Talk to your veterinarian before starting any supplement. Omega-3 fatty acids help keep the skin and coat soft and shiny and also support the heart, immune system, brain, and vision. Glucosamine supplements can support joint health.

Grooming

Both smooth and rough Collies need regular grooming for their double coat. Smooth Collies will not mat, but the undercoat still needs brushing out, and a weekly brushing removes cast-off hair. Rough Collies need more attention to avoid matting, especially behind the ears, around the elbows, on the legs, and on the undersides; brush down to the skin weekly and use a pin brush to lift loose undercoat.

Collies shed their undercoat about twice a year and need extra grooming, often nearly daily, during those heavy sheds. Spayed females tend to have one big shed a year; intact females shed about three months after a heat cycle and males around their birthday. A professional groomer can help with bathing and stripping out the second coat.

Beyond routine brushing and bathing, the coat needs no special care. General over-the-counter shampoos work fine, and conditioner can smooth and soften the coat. Trim nails about every other week depending on wear, and make ear cleaning and teeth brushing part of the routine.

Clean the ears at bath time and look in the ear canals while grooming, since some Collies produce more wax and need it more often. Contact your veterinarian if you see excessive discharge, a bad smell, redness, or itching. Brushing is also a good moment to check for ticks, fleas, lumps, bumps, or cuts.

Exercise

Collies are active dogs that need regular exercise, though energy varies by individual and family. They want aerobic activity and room to run and play, so a fenced yard plus daily walks suits them well. Avoid leaving them alone in the backyard for long stretches, since boredom brings barking.

Long walks on leash, swimming, hiking, and trips to the dog park all help tire a Collie out, and fetch in a fenced yard is another good option. They enjoy dog sports such as obedience, agility, and lure coursing, which let them show their speed and stamina while spending time with you. Keep a Collie contained or on leash in open areas, since they can be independent and curious.

These are people dogs that bond strongly with the whole family and do not do well left alone for eight or more hours a day. A Collie that gets enough activity is ready to go when it is time to go and able to settle when it is time to settle.

Collies are smart and need both mental and physical work, so an ideal home has time for enrichment, training, and play alongside the couch time they also love. Without enough to do they can grow bored, vocal, and destructive, so plan for variety and rotate activities, toys, and locations.

Training

Collies are very smart and easy to train, picking up basic commands and new tricks well when sessions are short, upbeat, and varied. Collies often enjoy training with their owners. Treats and favorite toys make good motivators, and positive reinforcement usually works best, kept consistent while you change up the challenges.

Like all breeds, Collies benefit from early socialization. Starting in puppyhood, introduce yours to new people, pets, and places to help them grow into a well-adjusted dog; puppy classes are a good start, and learning should continue for life. Collies are generally devoted and affectionate, rarely aggressive, and seldom growl or bite, though they may become watchful around strangers and alert you with intense barking.

With their herding background, Collies take well to positive-method work like herding and barn hunt, which give that instinct an outlet. A holdover from that work is a tendency to nip at ankles and heels when excited, so teach yours not to nip even in play.

These are gentle, patient companions, especially good with young children.
