Border Collies are some of the most intelligent dogs in the world, and they need a lot of physical and mental activity. They are medium sized dogs with an alert personality and huge sense of loyalty. They can be a challenge for even the most experienced dog owner. Border Collies will be tempted to herd anything that moves- including children, cars, people on bikes, cats, and squirrels, so a securely fenced yard is essential. Despite their high strung personality, they absolutely love people and make wonderful family dogs.
- Under-stimulated Collies are prone to ill-mannered and destructive behavior such as chewing, biting, barking, excessive digging, and aggression.
- Grey collie syndrome is a disorder characterized by an abnormally low concentration of neutrophils in the blood, resulting in a weakened immune system and creating a severely negative impact on the dog’s overall health.
- Another minor illness that Border Collies are prone to is osteochondritis dissecans. The abnormal growth of the bones can cause inflammation in the cartilages of the joints leading to severe pain and difficulty to walk.
