Collies are a popular breed of dog known for their intelligence, loyalty, and striking appearance. They originated in Scotland and were bred to herd sheep and other livestock.
One of the most distinctive features of collies is their coat, which can be either rough or smooth. Collies are highly intelligent and trainable, making them a great choice for first-time dog owners.
Collies are generally medium-sized dogs, with males weighing between 50-75 pounds. They are known for their strong herding instincts and can be prone to nipping at heels if not properly trained.
Collies are highly social dogs that thrive on interaction with their human family members. They require regular exercise and mental stimulation to prevent boredom and destructive behavior.

Appearance
Collies come in two coat types: Long-Haired Collie (Rough) and Short-Haired Collie (Smooth), and four main coat colors: Sable & White, Tri color, Blue Merle, and White.
Their size varies slightly depending on the country and breed standards, with American Collies typically being larger than their European counterparts.
Female Collies should weigh 50-65 pounds and stand 22-24 inches tall at the shoulders, while males should weigh 60-75 pounds and stand 24-26 inches at the shoulders, according to the American Kennel Club.
However, UK and FCI standards call for a smaller dog with a wither height of 51-56 centimeters for females and 56-61 centimeters for males.
Collies also have distinct regional characteristics, with American Collies often having longer muzzles and erect ears, while European Collies tend to have luxurious coats.
South American Collies have larger eyes, reminiscent of the classic "Lassie" type, and Australian Collies have a unique look of their own.
It's worth noting that outcrossing to Borzois may have introduced the "white" coat pattern, which is still recognized in the US but no longer in the UK.

Coat Color and Grooming

Collies come in two coat types: Rough (long hair) and Smooth (short hair). The Rough Collie has an abundant, straight outer coat that is harsh to the touch, and a soft, furry undercoat.
Both varieties shed moderately, but the amount of grooming necessary depends on the variety. The Rough Collie needs thorough brushing twice a week, while the Smooth Collie can get by with brushing once a week.
The Collie comes in four colors: sable, tricolor, blue merle, and white. Sable Collies often have a distinctive "Lassie-like" look, with a luxurious coat.
Brushing once a week is sufficient for the Smooth Collie, but daily brushing is even better to prevent gum disease and bad breath. Regular brushing also helps to prevent matting and tangling.
The Collie's coat will most often mat behind the ears and elbows, if at all. Daily brushing is recommended to keep it healthy and clean, while also giving you the opportunity to look for any ticks, fleas, lumps, bumps, or cuts.
Bathe your Collie as needed, usually every six to eight weeks, and trim their nails once a month. Regular grooming also helps to prevent ear infections, so be sure to check their ears once a week for dirt, redness, or a bad odor.

Smooth and Rough

Smooth Collies have a double coat, but their hair is much shorter than that of Rough Collies. They shed seasonally, but their short hair is easier to care for.
Rough Collies, on the other hand, have a long double coat that's perfect for herding sheep in Scotland. They were originally bred for this purpose.
The Smooth Collie's short hair was actually a result of being bred to help take animals to market, where they didn't need extra-long fur to protect them from the weather.
Both Smooth and Rough Collies have a double coat, but the key difference lies in their length.

Bearded
Bearded Collies have a distinctive appearance that's just as charming as their personality. Their shaggy mane requires daily brushing to keep it free of mats and dirt.
Beardies are known for their bouncy, carefree attitude and are very affectionate. They get along well with other pets.
Their coat is a key part of their physical characteristics, and it's not just for show - it's also a sign of their rugged heritage.
Personality and Behavior
Collies are known for their sweet, friendly, and gentle nature, making them a great fit for families with kids.
They're highly intelligent and learn quickly, which means they can pick up commands and behaviors in no time.
Collies thrive on attention and affection, and they'll often follow their owners around the house to be part of the action.
If you're considering bringing a Collie into your family, it's essential to socialize them from an early age to ensure they grow up to be well-rounded dogs.
Puppies with nice temperaments are curious and playful, and they'll often approach people and be held by them.
Collies need at least an hour of physical activity and mental stimulation each day to prevent destructive behavior and excessive barking.
They're best suited for agility classes, obedience training, herding, or as therapy dogs, which can help channel their high energy levels.
Collies are not typically aggressive dogs, but they may nip at ankles and heels when excited, a trait reminiscent of their herding days.
If you're planning to let your Collie off-leash, make sure they're in a fenced area or otherwise contained to prevent injury or loss.
Collies are loyal and affectionate, with few negative behavioral traits, and they'll often bond with the entire family.
Health and Care
Collies require regular grooming to keep their coat healthy and beautiful-looking. Aim to brush both smooth and rough collies at least once a week, paying special attention to the area behind a rough collie's ears and elbows.
Grooming during the shedding season will require more time and effort. You may also need to bathe your collie weekly to every 3 to 4 weeks, depending on their activity level and how often they get dirty.
To keep your collie's teeth healthy, brush their teeth daily and consider using dental chews and toys. Regular ear cleaning and nail trimming are also essential. It's also crucial to manage fleas, heartworms, and ticks by using preventative products and regularly checking your dog for ticks and removing them early.
Here's a quick rundown of your collie's dental care needs:
- Brush their teeth daily
- Use dental chews and toys to prevent dental problems
- Ask your vet for the best dental care options for your collie
Regular veterinary checkups are also vital to catch any potential health issues early on. Your vet can help you understand your collie's specific needs and provide guidance on managing potential health problems like Collie Eye Anomaly, Progressive Retinal Atrophy, and multidrug sensitivity.

Coat Care

Coat Care is a crucial aspect of Collie health and well-being. Regular brushing is essential to prevent matting and keep the coat healthy and clean.
Daily brushing is recommended to prevent matting behind the ears and elbows. It's also an opportunity to check for ticks, fleas, lumps, bumps, or cuts. Brushing will help remove dirt and stray hairs from the undercoat, which sheds twice a year.
During shedding season, Collies require extra care to remove their extensive fur. In some cases, a professional groomer may be needed to help bathe and strip the second coat. Bathing frequency depends on the Collie's activity level, time spent outdoors, and how well their coats are maintained.
The frequency of bathing can range from weekly to every 3-4 weeks, depending on the individual Collie's needs. It's essential to keep their coats clean and healthy to prevent skin problems.
Here's a brief guide to Collie coat care:
Bathe your Collie every 6-8 weeks, or as needed. Regular nail trimming and ear cleaning are also essential to prevent problems.
Health

Collies are generally healthy dogs, but like all breeds, they can be prone to certain health issues. One of the most common health problems in Collies is Collie Eye Anomaly (CEA), a condition that affects the deep structures of the eye and can lead to blindness.
Genetic testing can diagnose CEA in Collies as young as 5-6 weeks old. There is no treatment for CEA, but genetic testing can help breeders identify affected dogs and prevent the condition from being passed on to their puppies.
Collies can also develop Progressive Retinal Atrophy (PRA), a group of eye diseases that cause damage to the retina and can lead to blindness. Clinical signs of PRA can appear in Collies as young as 6 weeks old, and genetic testing is recommended for all breeders.
In addition to CEA and PRA, Collies can be at risk for other health issues, including seizures, allergies, and thyroid conditions. They can also develop conditions such as hip dysplasia and gastric dilatation and volvulus (GDV), which can be life-threatening if left untreated.

To stay on top of your Collie's health, it's essential to work closely with a veterinarian who can help identify potential issues early on. Regular check-ups and genetic testing can help ensure your Collie stays healthy and happy.
Here are some common health issues to watch out for in Collies:
- Collie Eye Anomaly (CEA)
- Progressive Retinal Atrophy (PRA)
- Seizures (epilepsy)
- Allergies
- Thyroid conditions
- Hip dysplasia
- Gastric dilatation and volvulus (GDV)
By being aware of these potential health issues, you can take steps to prevent them and ensure your Collie lives a long and healthy life.
Feeding and Nutrition
Collies typically do well on a diet of large-breed dry dog food from pet food companies such as Hill's, Purina Pro Plan, and Royal Canin.
You should feed your Collie 2 to 3 cups of high-quality dry food a day, divided into two meals. The amount may vary depending on your dog's size, age, build, metabolism, and activity level.
Dogs are individuals, just like people, and they don't all need the same amount of food. A highly active dog will need more than a couch potato dog.
Suggestion: Dog Breeds That Don't Need Grooming
The quality of dog food you buy also makes a difference - the better the dog food, the further it will go toward nourishing your dog and the less of it you'll need to shake into your dog's bowl.
For a 60-pound dog, a typical daily caloric intake is 1,000-1,200 calories. However, this may vary dramatically depending on energy levels.
Couch potatoes may require less than 1,000 calories, while canine athletes may need over 2,000 calories per day.
Always refer to the food bag and your veterinarian to determine the appropriate amount to feed your Collie, depending on their weight and activity level.
Your veterinarian will also take into account your Collie's age and pre-existing conditions when making a recommendation on caloric intake.
To prevent stomach upset and other serious stomach conditions, like bloat, you can use a slow-feed bowl to slow down your Collie's mealtime.
Some Collies may be over-enthusiastic at feeding time, causing them to rush their meal and not fully chew their kibble.
You can also consider adding supplements like omega-3 fatty acids to help keep your Collie's skin and coat soft, shiny, and healthy.

Care and Considerations
Collies are intelligent dogs that require regular exercise and mental stimulation to prevent boredom and excessive barking. A daily walk and yard play are sufficient, but they also benefit from ongoing obedience training or dog sports.
To keep your Collie happy and healthy, provide a moderate amount of physical activity, but also make sure they have time to spend with their family. Collies form strong bonds with family members and don't do well being left alone for long periods.
Here are some essential care considerations for Collies:
- Grooming: Brush your Collie at least once a week, and bathe them weekly to monthly depending on their activity level and coat length.
- Dental care: Brush your Collie's teeth daily, and use dental chews and toys to prevent dental problems.
- Veterinary care: Follow a vaccination schedule with your vet, and administer heartworm medication all year long.

To keep your Collie's coat healthy and clean, daily brushing is essential. This also gives you the opportunity to check for ticks, fleas, lumps, bumps, or cuts.
Collies shed their second coat, the undercoat, about twice a year. This is a moderate shedding breed, and they will blow their undercoat twice a year. They require extra grooming during blow-outs and may do best with a professional groomer during these times.
A different take: Bearded Collie Grooming
You'll need to bathe your Collie anywhere from weekly to once every 3 to 4 weeks, depending on their activity level, how much time they spend outdoors, and how well you maintain their coats. The longer their coat, the more often you may need to bathe them.
A Collie's diet should consist of high-quality meals, whether commercially available dog food or a recipe approved by a veterinary nutritionist. It's essential to provide a complete and balanced diet, and to avoid human food, which can cause problems for your dog's health.
Collies are intelligent and active dogs, requiring regular exercise and plenty of playtime. If they don't get enough activity, they may get bored and start barking more often. Games like fetch can be enjoyable for both you and your Collie.
Collies are prone to dental problems, so it's crucial to brush their teeth daily. You can also use dental chews and toys to prevent dental issues. Ask your vet for the best dental care options for your Collie.
To keep your Collie's ears clean and healthy, wipe them out weekly with a cotton ball dampened with gentle, pH-balanced ear cleaner. You should also trim their nails once a month, and check their ears and eyes regularly for signs of infection.

Smooth vs Rough Uses
Smooth Collies are generally preferred over Rough Collies as guide dogs for the blind due to their shorter fur and easier upkeep.
Both Smooth and Rough Collies can excel as companions and have been used as assistance dogs. In fact, Rough Collies can be used as PTSD, Mobility Assistance dogs, and Seizure Alert Dogs.

Some Collies are still used as general-purpose farm dogs, particularly those who value their gentler approach to guiding livestock.
The Smooth Collie's short hair makes them easier to groom, but Rough Collies can also make great farm dogs if you're willing to put in the extra grooming time.
In modern times, most Collies' main function is as a companion, and they have proven to excel in this role.
