Collies, like most dogs, typically begin to lose their baby teeth around 4 to 6 months of age, and their adult teeth should fully emerge by about 6 months to 8 months. This process includes the replacement of baby incisors, canines, and premolars with permanent teeth. By the time they are around 8 months old, most collies will have a complete set of permanent teeth. Regular dental care is important during this time to ensure healthy development.
