A Koolie is a breed of dog that originated in Australia. They are known for their high energy and intelligence.
Koolies are generally a healthy breed, but they may be prone to hip dysplasia and eye problems. Regular vet check-ups can help prevent and manage any health issues.
Koolies can be great with children if they are socialized properly and trained to interact with them. However, their high energy levels may be too much for some children.
