The Border Collie is an athletic, medium-sized herding dog that stands 18 to 22 inches at the shoulder and weighs 30 to 55 pounds. The build is muscular but nimble, made for fast, sharp movements, and the almond eyes carry an alert, intelligent expression. That intense gaze, the famous herding eye, is a breed hallmark.
The breed comes in two coat types, both medium in length. Colors range widely, including black and white, all-black, red, lilac, and blue.
Border Collies were bred to herd livestock on British farms, and many still herd today. The breed was recognized in 1995 and now ranks among the most popular family dogs as well. They are friendly with people they know and can be reserved with strangers.
Border Collies pair high intelligence with high energy. They suit active singles and families who can give them a job to do, and they make good teammates for Frisbee, hiking, and other games.

Care
The routines that matter most for this breed. Open one at a time.
Nutrition
A Border Collie should do well on a high-quality dog food, whether commercially made or home-prepared under your veterinarian's supervision. Match the diet to the dog's life stage (puppy, adult, or senior), and consider a formula built for active breeds. Keep clean, fresh water available at all times.
Feed adult Border Collies twice a day. Puppies need three meals a day on a regular schedule to help prevent hypoglycemia, or low blood sugar. Every food has a different caloric value, so follow the manufacturer's feeding guide and your vet's advice rather than assuming one bowl portion fits all. If you switch brands or flavors, transition slowly and confirm the new amount with your vet.
These high-energy dogs rarely become overweight, but portioning still matters. Measure meals with a cup and keep treats to no more than 10 percent of daily calories. Treats help with training, so account for them in the daily total.
Border Collies get their nutrients from a complete dog food, and some benefit from supplements at a vet's recommendation. Because the breed is so smart, puzzle feeders and interactive toys can slow down meals and add mental work.
Grooming
Border Collies have a dense, weather-resistant double coat that comes in two types: a medium-length rough coat that is feathered, and a shorter, coarser smooth coat. Both are groomed the same way. Go over the dog with a pin brush once or twice a week to keep the coat free of mats, tangles, and debris, and brush more often as needed.
During shedding season, brush daily and reach for an undercoat rake several times a week when they blow their coats. For routine bathing, a monthly oatmeal shampoo plus brushing two to three times a week keeps the coat clean and mat-free, and you can do it at home. Brush and bathe more often if your dog gets muddy.
Check the ears regularly for wax or debris that builds up from outdoor activity, and clean any buildup with a veterinary-approved cleanser. If you see inflammation, head shaking, or pawing at the ears, call your vet. Watch the eyes too, and talk to your vet if you notice discharge, inflammation, or injury.
Because they stay so active, Border Collies often wear their nails down and need less trimming than other breeds. Check every few weeks, and trim when you hear clicking on the floor. Provide regular dental care with at-home brushing and professional cleanings.
Exercise
The Border Collie is a high-drive, athletic breed that needs daily exercise well beyond a walk around the block or a quick romp in the yard. Plan on at least one to two hours a day, especially when young. Seniors may need only about 30 minutes a day if they start developing mobility issues.
They thrive with a job and space to run, and they make strong running companions who also enjoy brisk walks, hiking, swimming, and trips to the dog park. The breed often competes, and excels, in herding events, obedience, agility, rally, tracking, flying disc, and flyball.
Mental work matters just as much as physical activity. Puzzle toys and games keep their minds engaged, and keeping an appropriate activity ready helps a busy mind stay settled.
This is a breed for an active home. A Border Collie with too little to do may turn to chewing, digging, or excessive barking, so a steady outlet for that energy is essential.
Training
Border Collies are highly intelligent and trainable. They are keen to learn, pick up basic commands easily, and thrive in advanced work, which makes them excellent students. Focus on positive reinforcement and reward-based training, and avoid repetitive drills, which make them lose interest.
Early socialization is especially important. Give positive exposure to a wide variety of people and situations from early puppyhood through about seven months, and start as soon as you bring your puppy home. Obedience training that begins early and continues for life keeps them happy and supplies needed mental work.
They love their families but can be somewhat reserved with strangers. Because they tend to herd animals and people, they do best with older, well-behaved children, and they may try to herd other pets. Gentle redirection helps channel that instinct in positive ways.
The defining trait is nonstop energy paired with a working mind. Without enough mental work, Border Collies are prone to problem behaviors. Consistent training and steady mental challenges channel that drive.
